Features:
- Adds ten relay outputs for external control and protection circuits.
- Accepts commands from the LTB pilot path or external voltage sources.
- Shows energized relay states through indicators mounted on the board.
Seven relays expose two Form C contacts, while the remaining three expose four Form C contacts.
The RPL connection carries seven pilot-relay channels from the LAN I/O Terminal Board to the relay board.
Coil-source jumpers select between the LTB control path and voltage wired at the terminal interface.
The General Electric DS200RTBAG1A Relay Terminal Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Command Paths
- Pilot Relay Input: Seven low-level LTB relay channels reach the RTBA through RPL.
- External Drive: Relay coils can be picked up from a customer-supplied voltage at the terminals.
- Output Purpose: Contact outputs support external control and protection circuits.
- Customer Interface: Selected relay outputs can connect through HTB for field access.
Contact Distribution
- Dual-Form Relays: Seven relay positions provide two Form C contacts each.
- Four-Form Relays: Three relay positions provide four Form C contacts each.
- Terminal States: Contact points separate normally open, common, and normally closed paths.
- Relay Indication: Board LEDs identify the energized state of the relays.
Source Selection
- Group Voltage: G1 relay coils operate from 110 VDC.
- Jumper Control: JP1 through JP7 select sources for relay coils K20 through K26.
- Internal Path: One jumper position accepts control voltage arriving through RPL from the LTB.
- External Path: The alternate position uses voltage wired to the terminal board.
Interface Connections
- RPL Link: The 16-pin connector carries RX1 through RX7 pilot signals from the LTB.
- Control Return: The documented connector path provides the X2 return for relay control.
- Terminal Interface: Numbered points separate coil feeds from relay contact outputs.
- Plug Circuits: CP1PL through CP5PL and Y9PL through Y35PL form the pluggable-circuit group.
