Relay Output blocks provide 16 output circuits in four independent groups of four relay type outputs each. The block power may be either 115V or 230V AC. There are two types of Relay Output blocks: Relay Output Block (IC660BBR100), Relays Normally closed. Relay Output Block (IC660BBR101), Relays Normally open. Features Each group of four outputs on a Relay Block can be powered by a separate AC or DC source. Group to group isolation is 1500 volts. Relay blocks are compatible with a wide range of low power control and indicating devices such as relays, contactors, and lamps. Output devices may operate in the range of 5V to 250VAC or 5V to 220VDC, and switch up to 60 Watts or 125 VA. Configurable features of these blocks include: Output powerup defaults Output Hold Last State or default CPU Redundancy type Bus Switching Module control Block LEDs indicate proper block operation and CPU communications. Individual LEDS show the commanded output state of each coil. Compatibility These blocks can be used with any type of GE Fanuc Genius bus interface module. They can also be used with any PCIM or QBIM module. They are compatible with a Hand held Monitor identified by catalog number IC660HHM501 GEK-90486D-2 Chapter 7 Relay Output Blocks 7-3 Block Operation All of a Relay Output block s 16 relay type outputs are either normally open or normally closed (depending on the block version). Outputs are grouped into four groups of four relays. Each group of four shares a common input terminal. 7 GEK-90486D-2 Chapter 7 Relay Output Blocks 7-5 Field Wiring Field devices are wired to terminals 5 32, which accept AWG #22 through AWG #12 wires. Do not overtorque the terminal screws. Block Power Relay Output blocks require a 115 VAC or 230 VAC power source. Voltage selection is made by jumpers on the Terminal Assembly. When shipped from the factory, the power selection jumpers are set for 115 VAC operation. For 230 volt AC power, change the jumpers as shown below. Care must be taken to ensure correct jumper placement. Incorrect jumper placement may result in damage to the block. Connect an appropriate power source to the H and N terminals (5 and 8). Note If Class 1 Division 2 conditions must be met for Factory Mutual, install an external 250 volt 1/8 amp slow blow fuse in series with the Hot AC power connector as shown below. With the external fuse indicated, this block meets FM Class 1 Division 2 requirements. Wiring for Output Devices Power for AC loads may come from the block AC power supply or other AC source(s). Power for DC loads may come from one or more DC sources. Each group may use a separate AC or DC source. External Fuses and Snubbers Relay blocks have no internal fuses. Following normal practices, external fuses of 2 amps or less can be installed in series to protect loads. External snubbers are not necessary for correct operation of the block. However, the use of snubbers is recommended. Snubbers will protect loads from switching transient pulses and lengthen the contact life of the relays. Use a diode connected in parallel with a DC inductive ~ OR ~ load or an R C network across the contacts. 7 7-6 Genius I/O Discrete and Analog Blocks User s Manual September 1993 GEK-90486D-2 Using a Relay Block as a BSM Controller Both types of Relay Block (IC660BBR100 and BBR101) can be used to control a Bus Switching Module. There are two different BSM versions available. It is important to match the BSM to the type of voltage that will power the block s outputs. If this voltage will be 24/48 VDC, BSM version IC660BSM021 is required. If the voltage will be 115 VAC or 125 VDC, IC660BSM120 is needed instead. Connect the BSM to the block as shown below. Block and Points Powered by 115 VAC If the block and points are powered by 115 VAC, connect one wire of BSM version IC660BSM120 to point 1 and connect the other BSM wire to N. Jumpering terminal J1 to COM as shown below allows the points to operate on the same 115 VAC source that powers the block. Block Powered by 230 VAC, Points Powered by 24 48 VDC If the block is powered by 230 VAC and the points are powered by a 24 48 VDC source, connect one wire of BSM version IC660BSM021 to point 1 and the other to DC (24 48VDC). Block Powered by 230 VAC, Points Powered by 115 VAC or 125 VDC If the block is powered by 230 VAC and the points are powered by either a 115 VAC source or a 125 VDC source, use BSM version BSM120. Connect one wire of the BSM to point 1. For a 125 VDC source, connect the other BSM wire to DC . For a 115 VAC source, connect the other BSM wire to the neutral side of the power supply. 7 GEK-90486D-2 Chapter 7 Relay Output Blocks 7-7 Block Configuration The configurable features of a Relay Output Block are listed below. For many, the factory setting will not need to be changed. Features marked with an asterisk in the table are configured from the Program Block ID screen of the Hand held Monitor, as explained in chapter 3. 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 block s features should be decided on and recorded on a copy of the Configuration Worksheet printed on the next page. |
