Description
The GE General Electric DS200RTBAG1A / DS200RTBAG1AEB is an RTBA Relay Terminal Board designed for the GE Mark V Speedtronic control system. It is an optional board used in compatible GE drive and exciter cabinets and provides ten additional relay circuits. The board uses seven DPDT relays at positions K20–K26 and three 4PDT relays at positions K27–K29. The relays can be driven by pilot relays on the LAN I/O terminal board or by external user control. The DS200RTBAG1A configuration uses 110 VDC relay coils, with 10 A contacts on the DPDT relays and 1 A contacts on the 4PDT relays.
