The General Electric DS200RTBAG1A is a relay terminal board (RTBA) developed for the Mark V board series. This optional board can be installed in a number of GE brand drive or exciter cabinets. When installed, this card provides the drive with an additional ten relays. These relays can be driven either by the pilot relays housed on the LAN I/O terminal board (GE P/N 531X307LTB) or by the user remotely.
DS200RTBAG1A provides access to an additional ten relays when installed in a drive or exciter. Seven of the relays found on the board are DPDT relays that feature 2 Form C contacts. The remaining three relays are 4PDT type, with four Form C contacts. The DPDT relays are found in positions K20 through K26. Voltages for these relays include a 110 VDC coil and 10 A contacts. K27 through K29 are the designated positions for these three relays. Relay voltages for these include a 110 VDC coil and 1 A contacts. Each relay found on the board is protected from surges and interruptions by a 130 VAC metal oxide varistor (MOV). Should any relays burn out, each is easily easily replaceable by the user.
Manufacturer provided installation parameters for both the relay terminal board and the installed drive must be followed. These instructions will protect the entire drive unit from any accidental damages. Wiring guides for installing DS200RTBAG1A are available in both the user manual and device datasheet. Technical support for all boards in the Mark V series was originally provided by General Electric.
