Two 32 circuit DC blocks are available: 32 Circuit 12/24 VDC Source block (IC660BBD024), which provides current to field output devices. 32 Circuit 5/12/24 VDC Sink block (IC660BBD025), which receives current from field output devices. Both blocks operate at a nominal 12 to 24 volts DC. The Sink version is also +5 volt TTL compatible. Features 32 Circuit DC I/O Blocks interface to a wide range of input devices, including both 2 wire and 3 wire electronic proximity switches. Outputs may be low power control and indicating devices such as relays, contactors, and lamps. These blocks have 32 identical discrete I/O circuits, each easily configured to be an input or an output. Output circuits can be directly connected to input circuits without the use of other components or inversion of logic states. This flexibility provides maximum design and application efficiency. Each circuit contains built in protection when used as an output, protecting the driver while allowing short time surges. It also protects against shorted loads caused by wiring errors. Block LEDs indicate proper block operation and CPU communications. Fault reporting can be enabled or disabled circuit by circuit. Additional configurable features include: Output Pulse Test capability Selectable Input Filter Time from 1mS to 100mS Output powerup defaults Output Hold Last State or default CPU Redundancy type Bus Switching Module control* Compatibility These blocks are compatible with a phase B Hand held Monitor (IC660HHM501) only. For the Series Six PLC, a phase B Bus Controller (IC660CBB902 or 903) or a phase A Bus Controller (IC660CBB900 or 901) version 1.3 or later is required. They are compatible with all other GE Fanuc Genius bus controllers, PCIM, and QBIM modules. * If used to control operation of a Bus Switching Module, BSM IC660BSM021 is required. The block must operate at 18 volts or above. .5A Max/Pt 16A Max Total a44486 5/12/24 VDC Sink In/Out GENIUS GE Fanuc 9 9-2 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Specifications Block Type: Catalog Numbers: 32 Circuit 12/24 VDC Source: I/O Block Terminal Assembly Electronics Assembly 32 Circuit 5/12/24 VDC TTL Sink: I/O Block Terminal Assembly Electronics Assembly DC 32-circuit discrete input and output IC660BBD024 IC660TBD024 IC660EBD024 IC660BBD025 IC660TBD025 IC660EBD025 Size (height x width x depth): Weight LEDs (I/O Block) LEDs (each circuit) Block to Block Isolation Heat Dissipation 8.83 (22.44cm) x 3.56 (9.05cm) x 4.42 (11.23cm) 4 lbs.

If the block is configured as a combination block, output feedback is provided in the corresponding input references. 32 Circuit DC Source I/O Block A 32 Circuit DC Source I/O Block has all output devices connected to the negative ( ) side of the power supply. Inputs control the positive (+) side of the power supply. For outputs, an ON condition is logic 1 and an OFF condition is a logic 0.

Inputs control the negative ( ) side of the power supply. For outputs, an ON condition is logic 0 and an OFF condition is a logic 1. When outputs in a sink type block are connected to inputs in a sink type block, a logic 1 command to the output will turn the output ON and produce a logic 1 to the PLC. .1 F Configured as an Input Configured as an Output * a42315 I/O Smart Switch Control Logic Electronics Assembly Terminal Assembly Field Connections 3.3K DC+ DC DC DC+ To/From Other Circuits * 39V Zener Diode Input Device Output Device Circuit LEDs Each circuit has its own LED. If the circuit is configured as an input, the LED indicates the presence of threshold voltage at the input terminal. If the circuit is configured as an output, the LED indicates the actual state of the load. 9 9-4 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Inputs and Outputs The block can be configured as an inputs only, outputs only, or combination block. Regardless, the block always sends 4 bytes of data each bus scan, and accepts 4 bytes of data each bus scan. If the block is configured as an inputs only block, all circuits must be inputs. The block will use 32 input references and NO output references. If the block is configured as an outputs only block, all circuits must be regular outputs; no feedback analysis can be performed. The block will use 32 output references and NO input references. If the block is configured as a combination block, it can have any mix of input and/or output circuits. The block will use 32 input references and 32 output references. The actual state of each output circuit will be returned to the CPU in the corresponding input reference location. The CPU can monitor the feedback state to verify (after an appropriate delay) that the output switching device has operated properly and that the load has the proper voltage and current applied. Appendix B shows reference usage for a Series 90, Series Six, or Series Five PLC. Input Data Format A 32 Circuit DC I/O Block broadcasts 4 bytes of input data each bus scan.

Press a function key to see the next 16 circuits. REF 17 32IO 9 GEK-90486D-2 Chapter 9 32 Circuit DC Input/Output Blocks 9-5 Diagnostics The block monitors outputs for overload conditions, and checks the actual state of each output switch against its commanded state. The block reports all faults to the Hand held Monitor. Individual circuits can be configured not to report faults to the CPU. Short Circuit diagnostic If the output is commanded to go on and current exceeds 5 amps for 1mS, the block automatically turns the circuit off and sends a FAILED SWITCH message. The circuit must be reset by cycling power to the block, or by sending a Clear Faults command from the Hand held Monitor or the CPU. Surge Current Protection These blocks handle steady state loads of 0.5 amps during normal operation. They will safely switch loads between 0.5 amps and 4 amps, as shown below. To protect the block, surge currents should not exceed these levels. For example, a surge current of 4 amps should not be more than 10mS in duration. A surge current of 1 amp should not exceed 30mS. 0.5 1.0 2.0 3.0 10 20 30 CURRENT (AMPS) TIME (mS) a44135 4.0 5.0 Caution Failure to operate a circuit within these limits may result in thermal overload and damage to the block. The electronic protection will not turn the load off until the current reaches 5 amps. Overcurrent Protection If an output is commanded to go on and the load exceeds 5 amps for 1mS, the block automatically turns off the circuit, and sends the FAILED SWITCH message. The circuit must be reset by cycling power to the block, or by sending a Clear Faults command to the block. 9 9-6 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Field Wiring Field devices are wired to terminals 5 32, which accept two#14 solid wires, or two #16 stranded wires. Do not overtorque the terminal screws. Sink Block Any circuit can be an input or output. Connect one terminal of a field device to DC power and the other to the block (terminals 10 41). All I/O devices must return to the same power circuit. Connect outputs to the positive side of the power supply and inputs to the negative side. For block power, connect a DC source to the DC+ terminals (6 9) and the return to the DC terminals (42 46). Depending on layout and current loads, positive and negative connections can be bussed and made by single wires to the block or power source. Do not apply more than 5.25 volts to the +5V terminal. Damage to the block might result. For 5 volt Sink applications only, jumper the +5V terminal to any DC+ terminal. For 12 or 24 volt sink applications, do not jumper the +5V terminal to DC+. It will damage the block. Leave the +5V terminal open. DC Sink Block, Power Disconnects Since block power is the same as circuit power, it is important to wire block power disconnects so that block power and input power will be removed at the same time. If circuit power is not removed at the same time as block power, the block may power up when multiple inputs are activated, even though one leg of power has been removed from the block. Caution -90486D-2 Chapter 9 32 Circuit DC Input/Output Blocks 9-7 Field Wiring: Source Block For a Source block, connect outputs to the negative side of the power supply and inputs to the positive side. Caution If circuit power is not removed at the same time as block power, the block may power up when multiple inputs are activated, even though one leg of power has been removed from the block. Wiring for a Bus Switching Module If the block will be used as a BSM Controller, connect the Bus Switching Module like a load to circuit 1. Connect either of the BSM s pigtail wires to terminal 10. For a DC Sink block, connect the other BSM wire to DC+. For a DC Source block, connect the other BSM wire to DC . Block Power Disconnects Since block power is the same as circuit power, it is important to wire block power disconnects so that block power and input power will be removed at the same time. 9 9-8 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Block Configuration The configurable features of a 32 Circuit DC Input/Output Block are listed below.

The rest of the features can be configured either using a Hand held Monitor, or by sending a Write Configuration datagram to the block from the host. Before configuration begins, the features of each 32 Circuit DC Input/Output block should be decided upon, then recorded on a copy of the Configuration Worksheet printed on the next page. |
