Features:
- Provides sixteen isolated relay-output channels for TPS Process Manager I/O.
- Uses compression terminals for the connected field conductors.
- Protects each relay path with a designated time-delay fuse.
Assembly number 51309150-125 identifies the MU-TDOR22 relay FTA and its compression-terminal execution. Terminal and fuse records should use both designations.
The board separates Process Manager output commands from externally powered loads, allowing plant relays, lamps or solenoids to be switched through isolated contacts.
Trace all field sources and record F1–F16 assignments before replacement. Use the approved fuse type and verify the paired I/O interface before applying power.
MU-TDOR22 51309150-125 is matched by assembly number, terminal style and TPS interface requirement.

- Switch independently powered alarm and annunciator circuits from a TPS system.
- Drive contactor or interposing-relay coils through isolated field contacts.
- Maintain fused Process Manager output terminations in legacy control cabinets.
- Fuses F1 through F16 protect the individual relay-output paths.
- Use the specified 3 A, 250 V time-delay replacement rather than a fast substitute.
- Investigate the field fault before replacing a fuse and returning the channel to service.
- Match the FTA to the specified TPS Process Manager output interface and cable.
- Keep all sixteen controller channels aligned with the terminal and fuse numbering.
- Confirm that the connected field circuits use the relay isolation provided by this assembly.
- Sixteen I/O commands operate separate relay contacts at the field termination boundary.
- The FTA does not create field power; each switched load uses its own approved source.
- Output proof should compare the TPS command, relay action and actual load response.
