DS200TCPDG2BEC 125V DC GE TCPD Board

Essential Highlights: GE DS200TCPDG2BEC

• Brand & Model: General Electric DS200TCPDG2BEC — genuine USA-made Mark VI series board.
• Core Function: Acts as the central Power Distribution Module. It feeds 125V DC to TCPS, TCEA, and DTBC/DTBD boards.
• Voltage Inputs: Accepts external 115/230V AC and 125V DC via hardwired TB1. Converts AC to DC through the DACA (JZ2).
• Switching Control: Features individual core power switches (SW1–SW8). Lets you power down R1, R2, R3, R5, P1 (X, Y, Z) independently.
• Solenoid & Ignition Power: Supplies 120/240V AC for ignition transformers (DTBC). Also provides 125V DC for solenoids via J8A–J8D.
• Wetted Contact Inputs: Powers DTBA boards in Q51 and Q11 cores for contact input sensing (J12A, J12B).

Mechanical Design & Board Layout

• Connector Map: Clearly labeled ports—J1R, J1S, J1T, J1C, J1D for TCPS boards. J7W, J7X, J7Z feed P1 core.
• PD Monitoring: JPD in R5 core sends power status to CTBA board for AC/DC supervision.
• Unused Connectors: J15, J16, J19, J20, J2R, J2S, J2T, J7A, J12C, J17, J18 remain reserved or not commonly used.
• Jumper Configuration: BJS hardware jumper isolates ground for external reference systems. No software settings required.
• Auxiliary Input: JZ4 accepts isolated AC for uninterruptible/black-start inverter backup.

Installation & Signal Wire Guide

• Plug-and-Play Replacement: Transfer wires terminal-to-terminal. No need to trace circuits.
• Terminal IDs: Look for labels like AC1N, AC1H, AC2N, AC2H on the board edge.
• Wire Preparation: Each wire must carry a durable tag showing its terminal ID.
• Screw Termination: Loosen the screw with a screwdriver, insert the wire, then tighten.
• Security Check: Always pull the wire gently to confirm a firm grip.
• What You Receive: 1x GE DS200TCPDG2BEC board. Mounting hardware not included.

• Dispatch: Orders ship within one business day.

Frequently Asked Questions (FAQ)

1. Does the DS200TCPDG2BEC require programming?

No. The TCPD board has zero software or firmware. It is a pure hardware power router. Just connect wires and power up.

2. Which cores get power directly from this board?

It powers the TCPS boards in R1, R2, R3, R5, and R cores. It also feeds TCEA, TCTG, DTBC, DTBD, and CTBA boards. Digital IO cores (Q11, Q21, Q51) draw power from their associated IO core, not directly from PD.

3. How do I select lower voltage for DTBC contact #18?

Use the JZ3 connector instead of the standard JZ2. This provides a reduced voltage for that specific output circuit.

4. I see many unused connectors on the board. Is that normal?

Yes. Connectors like J15, J16, J19, J20, and J2R/T are placeholders for expanded systems. Most standard Mark VI configurations leave them open.

5. What is the JZ4 connector for?

JZ4 connects an auxiliary AC source. Engineers often use it for a Black Start Inverter or an uninterruptible power supply (UPS).

6. Buying advice: Should I choose the DS200TCPDG2BEC or an older revision?

Always pick the DS200TCPDG2BEC revision. It includes the BJS isolation jumper and supports both standard and low-voltage special outputs. It is the most flexible Mark VI TCPD variant for turbine retrofits.
