DS200TCRAG1A GE Mark V LM Relay Output Board

Product Description

The DS200TCRAG1A is a Relay Output Board manufactured by General Electric for the Mark V LM turbine control system. It controls relay-based output signals through relays designated K1 to K30, allowing the controller to operate external devices such as solenoids and ignition transformers. Its relay population and output configuration vary according to the board's installation position within the digital I/O cores.

Functional Description

The DS200TCRAG1A provides relay switching outputs within the GE Speedtronic Mark V LM control system. Each digital I/O core normally contains two TCRA boards. The TCDA boards send control signals to the TCRA, instructing individual relays to open or close according to the control logic.

The board can accommodate up to 30 relays, designated K1 through K30. However, the actual relay population depends on its installation position:

• The TCRA board at position 4 of the Q11 core contains only four relays.
• Other TCRA board positions normally contain 30 relays.
• The TCQE board connects to the four-relay TCRA board through the JO connector.

Relay Output Configuration

Certain TCRA positions support configurable relay outputs for solenoid power applications. For example, the first 18 relays on the TCRA board at position 4 of the Q51 core can be configured to provide a power source for operating solenoids.

Furthermore, the first 16 relays on the TCRA board at position 5 of the Q11 or Q51 core support this configuration. Hardware jumpers on the DTBC and DTBD terminal boards establish the required arrangement.

In addition, the TCRA board at position 5 of either Q11 or Q51 can provide two additional wetted contact outputs, numbered 47 and 48, through power connectors J19 and J20. The PD core supplies 120/240 VAC to the DTBD board through these connectors. These outputs are typically used for ignition transformer signals.

Configuration limitation: The first 18 solenoid outputs in the Q21 core cannot be configured as solenoid power sources. Therefore, the core location and terminal-board jumper arrangement must be checked before selecting the required output configuration.

Frequently Asked Questions

Q: Does the DS200TCRAG1A always contain 30 relays?

A: No. Although the board supports up to 30 relays, the TCRA board installed at position 4 of the Q11 core contains only four relays. Other installation positions normally contain 30 relays.

Q: Can the DS200TCRAG1A provide power for solenoid operation?

A: Yes, in specified configurations. The first 18 relays at position 4 of Q51 and the first 16 relays at position 5 of Q11 or Q51 can be configured for solenoid power applications using hardware jumpers on the DTBC and DTBD terminal boards.

Q: What are connectors J19 and J20 used for?

A: They provide the connection for 120/240 VAC from the PD core to the DTBD board and support two additional wetted contact outputs, numbered 47 and 48, on the TCRA board at position 5 of Q11 or Q51.
