GE Manufacturing IS200TRLYH2C Policy Series Mark VI/VIe Function Module

Part Number IS200TRLYH2C Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS200TRLYH2C is a Relay Output with a Contact Sensing Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. 

The Relay Output with contact sensing (TRLYH2C) terminal board holds 12 plug-in magnetic relays. The first six relay circuits are Form-C contact outputs to drive external solenoids. A standard 125 V dc or 115 V ac source with fuses and on-board suppression is provided for field solenoid power. TRLYH2C holds 12 plug-in magnetic relays. The first six relay circuits are Form-C contact outputs to drive external solenoids. A standard 24 V dc source with fuses and onboard suppression is provided for field solenoid power. The next five relays (7-11) are unpowered, isolated Form-C contacts. Output 12 is an isolated Form-C contact with a non-fused power supply, used for ignition transformers. For example, 12 NO contacts have jumpers to apply or remove the feedback voltage sensing. TRLYH1C and 2C are the same as the standard TRLYH1B board except for the following: Six jumpers for converting the solenoid outputs to dry contact type are removed. These jumpers were associated with the fuse monitoring. Input relay coil monitoring is removed from the 12 relays. Relay contact voltage monitoring is added to the 12 relays. Individual monitoring circuits have voltage suppression and can be isolated by removing their associated jumper. High-frequency snubbers are installed across the NO and SOL terminals on the six solenoid driver circuits and the special circuit, output 12. 

INSTALLATION:Connect the wires for the 12 relay outputs directly to two I/O terminal blocks on the terminal board TRLYH2C Terminal Board Wiring. Each block is held down with two screws and has 24 terminals accepting up to 12 AWG wires. A shield terminal strip attached to the chassis ground is located immediately to the left of each terminal block. Connect the solenoid power for outputs 1-6 to JF1 normally. JF2 can be used to daisy-chain power to other TRLYs. Alternatively, power can be wired directly to TB3 when JF1/JF2 are not used. Connect power for the special solenoid, Output 12, to connector JG1. OPERATION: Relay drivers, fuses, and jumpers are mounted on the TRLYH2C. Relays 1-6 have a 250 V MOV for transient suppression between the NO and power return terminals. Relays are driven at the frame rate and have a 3.0 A ac rating. The typical time to operate is 10 ms. The relay outputs have a fail-safe feature that votes to de-energize the corresponding relay when a cable is unplugged or communication with the associated I/O board is lost. For simplex operation, a connector carries control signals and monitors feedback voltages between the I/O board and TRLY through JA1. For TMR applications, relay control signals are fanned into TRLY from the three I/O packs/boards R, S, and T through plugs JR1, JS1, and JT1. These signals are voted and the result controls the corresponding relay driver. The 28 V power for the relay coils comes in from all three I/O boards and is diode-shared.
