DS200DTBCG1A

DS200DTBCG1A is a Contact Output Termination Module developed by GE. It is a part of Mark V series. Q11, Q21, and Q51 contain the Contact Output Termination Module (DTBC). DTBC is linked to the TCRA's 30 relays in Q21 and Q51 locations four and five. DTBC hardware jumpers can be used to configure eighteen of the thirty outputs on DTBC in Q51 as solenoids. The DTBC in Q11 is linked to the four contact output relays on the TCRA in Q11. The Q11 DTBC's hardware jumpers are specifically configured for gas manifold blow-off valve control.

DS200DTBCG1A Connectors

• JS1-JS8: Reads the relay signals from the TCRA board in location four.
• J8: Receives power from the TCPD board in the PD core for the solenoids.
• J15 connects to J16 and provides 125 V dc power to contact outputs 16, 17, and 18. On the Q11 core, this is not commonly used.
• J16 connects to J15 and provides 125 V dc power to contact outputs 16, 17, and 18. Only connectable in the Q51 core. On the Q11 core, this is not commonly used.

Hardware Configuration

• P1/M1 through P18/M18: Contact outputs #1 through #18 are enabled by solenoids.
• To enable solenoid power, both must be in, or both must be out. This convention is not followed by the Q11 DTBC configuration for gas manifold blow-off valve control.
