Description
🔹 Product Description
The GE General Electric DS200RTBAG1A, with assembly designation DS200RTBAG1AEB, is an RTBA Relay Terminal Board designed for GE Mark V Speedtronic turbine control and compatible drive or exciter cabinets. The board is an optional interface board that adds relay outputs and provides terminal connections for relay control circuits. It can be driven by pilot relays on the GE 531X307LTB LAN I/O terminal board or by external user control.
The DS200RTBAG1A provides ten relays in total. Seven are DPDT relays with two Form C contacts, while three are 4PDT relays with four Form C contacts. The board also includes relay status LEDs, MOV surge protection, terminal connections, plug connectors, and movable hardware jumpers for configuring coil-voltage sources. The G1A version is associated with the 110 VDC relay-coil configuration; the exact installed board and relay markings should be verified before replacement.

🔹 Common Questions & Answers
Q: What is the GE DS200RTBAG1A?
A: It is an RTBA Relay Terminal Board used in GE Mark V Speedtronic control systems and compatible drive or exciter cabinets.
Q: What is the DS200RTBAG1AEB designation?
A: DS200RTBAG1AEB is an assembly/revision designation associated with the DS200RTBAG1A RTBA board. The complete marking should be matched when ordering a replacement.
Q: How many relays are on the board?
A: The DS200RTBAG1A contains ten relays. Seven are DPDT and three are 4PDT.
Q: What are the relay contact ratings?
A: The seven DPDT relays are documented with 110 VDC coils and 10 A contacts, while the three 4PDT relays use 110 VDC coils and 1 A contacts.
Q: What is the function of the RTBA board?
A: It provides additional relay outputs and terminal interfaces for control signals in compatible Mark V drive and exciter installations.
Q: How are the relays controlled?
A: The relays can be driven from pilot relays on the GE 531X307LTB LAN I/O terminal board or remotely by the user, depending on the system configuration.
Q: Does the board have relay status LEDs?
A: Yes. Each relay has an LED indicator that shows when the associated relay is powered.
Q: What is the purpose of the jumpers?
A: The board uses Berg-type/manual jumpers to configure coil-voltage sources and related circuit connections. Jumper positions should match the original installation configuration.
Q: Is DS200RTBAG1A compatible with every RTBA board?
A: No. GE Mark V RTBA boards are available in different coil-voltage and revision configurations. Confirm the complete part number, relay arrangement, coil voltage, jumper configuration, and existing wiring before replacement.
Q: What should I check before installation?
A: Verify the complete DS200RTBAG1AEB marking, relay types, coil voltage, terminal wiring, jumper positions, connector condition, and the original Mark V cabinet documentation.
Q: Is the DS200RTBAG1A still a current-production GE board?
A: It is a legacy Mark V component rather than a current-generation GE control product. It is primarily used for maintenance, repair, replacement, and restoration of existing systems.
