The DS200RTBAG2A and DS200RTBAG2AHC are Relay Terminal Board (RTBA) modules engineered by GE for the Mark V Speedtronic turbine control platform. The DS200RTBAG2AHC operates with a 24 V DC coil, while the DS200RTBAG2A uses 110 V DC coils. Each DS200RTBAG2A board adds ten relays to the host system, comprising seven DPDT relays (each with two Form‑C contacts, rated 10 A) and three 4PDT relays (rated 1 A). All relays are protected by 130 V AC MOVs and feature individual LED status indicators. Supporting both remote and LAN I/O terminal control, the DS200RTBAG2A and DS200RTBAG2AHC provide reliable relay termination and signal distribution for turbine and exciter systems.

10 additional relay points: Installs into host cabinets to expand relay capacity for turbine and exciter systems.
Mixed relay configuration: Seven DPDT relays (two Form‑C contacts each) and three 4PDT relays (four Form‑C contacts each).
Individual LED status indicators: Per‑relay lamps provide instant visual confirmation of energisation state.
130 V AC MOV surge protection: Each relay protected by a metal oxide varistor, safeguarding against voltage transients.
Individual relay replaceability: Any of the ten relays can be replaced without changing the entire board.
LAN and remote I/O control: Supports both local network communication and remote terminal operation.
Jumper‑selectable configuration: On‑board berg‑type jumper pins allow customisation of control power sources and signal routing.
Inter‑board connectivity: Includes 16‑pin RPL connector for LTB interface, 2‑pin OPTPL connector, and multiple PL connectors for pluggable circuits.
Stab connectors (CPH/CPN): Provide flexible control power supply to pluggable circuits.
Dual voltage variant design: Choose DS200RTBAG2A for 110 V DC applications or DS200RTBAG2AHC for 24 V DC systems.
Industrial‑grade construction: Engineered for power generation environments with 0°C to +60°C (or –20°C to +70°C) operating range.
Hot‑swap compatibility (redundant configurations): Supports maintenance without complete system shutdown in redundant setups.
Terminates and distributes relay control signals between field devices (contactors, indicators, interlocks) and the Mark V controller.
Converts low‑power logic signals from the LTB into high‑current relay outputs capable of driving industrial loads.
Provides galvanic isolation between control logic and field circuits via electromechanical relays.
Enables remote operation of relays via user commands or automatic pilot relay activation from the LTB.
Protects sensitive control electronics from voltage spikes through MOV surge suppression on each relay.
Supports custom configuration of control power sources and signal routing via hardware jumpers.
Delivers visual relay status feedback through LED indicators for rapid on‑site diagnostics.
Allows maintenance personnel to replace individual failed relays without decommissioning the entire board.
Q1: What is the primary difference between DS200RTBAG2A and DS200RTBAG2AHC?
A1: The primary difference is the coil voltage: the DS200RTBAG2A uses 110 V DC coils, while the DS200RTBAG2AHC operates with 24 V DC coils. Both offer identical relay configuration and functionality.
Q2: How many relays does the DS200RTBAG2A provide?
A2: The DS200RTBAG2A provides ten relays total — seven DPDT relays (two Form‑C contacts each) designated K20–K26, and three 4PDT relays (four Form‑C contacts each) designated K27–K29.
Q3: What is the current rating of the DPDT relay contacts?
A3: Each DPDT relay contact on the DS200RTBAG2A is rated for 10 A, suitable for switching moderate‑power industrial loads such as contactor coils and indicator lamps.
Q4: Does the board provide protection against voltage surges?
A4: Yes, each relay on the DS200RTBAG2A is protected by a 130 V AC metal oxide varistor (MOV) that suppresses voltage transients and safeguards connected equipment.
Q5: Which manual covers the installation of the DS200RTBAG2A?
A5: The official instruction manual is GEI‑100167B for the DS200RTBAG2A and GEI‑100167 for the DS200RTBAG2AHC. The board also references GEI‑100022 for related LTB interface details.
