Product Short Description
Product Name: General Electric DS200RTBAG3AFB RTBA Relay Terminal Board (Mark V Series)
Product Overview: An RTBA relay terminal board designed for GE’s Mark V control system, providing relay connections and control functions within a drive cabinet assembly. It manages 10 relays with 115 VAC coil voltage and offers extensive connectivity for industrial process control.
Description
Technical Specifications:
- Product Type: RTBA Relay Terminal Board
- Series: Mark V
- Relays: 10 relays with 115 VAC coil voltage
- Relay Type: K20–K26 are DPDT type (two 10 A C-type contacts each); K27–K29 are 4PDT type (four 1 A C-type contacts each)
- Surge Protection: 130 VAC MOV (metal oxide varistor) on each relay
- Connectors: Up to 52 screw-type terminals (TB1–TB52) for I/O connections
- Power Selection: Berg-type jumpers (JP1–JP10) for internal/external power source selection per relay
- Coil Voltage: 115 VAC
Structural & Material Features: The board’s “G3” designation indicates a Group 3 style PCB with normal coating. The relays are easily removable and replaceable. Status LEDs illuminate when coil energization occurs for runtime visual verification. The board mounts via standoffs within the cabinet assembly.
Working Principle: Low-power control signals from the Mark V controller drive the on-board electromechanical relays, whose contacts switch higher-power loads (motors, transformers, etc.). Berg jumpers configure each relay for internal or external power, latching or pulse operation.
Application Scenarios: Drive cabinet assemblies in GE Mark V control systems; used for relay interfacing, excitation control, and sequential control of high-power industrial equipment such as turbines and generators.
Installation & Usage Notes: Install with proper ESD protection. Configure Berg jumpers (JP1–JP10) for the desired power source and operating mode. Verify wiring at terminals TB1–TB52. LEDs provide visual confirmation of relay coil state during commissioning.
