Output Status Checks
Features:
- Eight isolated switching channels: Normally-open PhotoMOS outputs provide separate discrete field-output paths in the specified FLEX I/O / ControlNet arrangement.
- Terminal-base-dependent load ratings: The official sheet distinguishes the TB3 and TBN output-voltage limits, making base identification part of the electrical match.
- Local condition indication: A two-state module LED, eight output LEDs and watchdog, undervoltage and bus-timeout diagnostics support maintenance assessment.
The FXDOM01 converts the installed control system's discrete commands into eight isolated output circuits. Mitsubishi documents the module together with the applicable terminal bases and separate module and bus supplies, allowing the output hardware to be evaluated as part of the complete field-wiring arrangement.
A replacement should retain the documented FXDOM01 identity, terminal-base type and electrical load conditions. The official sheet identifies the licensed technology boundary and assigns product support to Mitsubishi Hitachi Power Systems; similar mechanical appearance or a FLEX I/O connection must not be treated as evidence of universal interchangeability.
An exact-model OEM lifecycle designation for FXDOM01 has not been verified. Moore Automated can quote replacement modules and spares against the complete item identification and supplied condition.

Base-dependent output limits
The official specification distinguishes 120 V DC / 120 V AC at 0.5 A with 1794-TB3 from 220 V DC / 230 V AC at 0.5 A with 1794-TBN. Do not apply the higher-voltage rating to a TB3 arrangement. Maximum output ON resistance is 3.2 ohm.
Two documented supply paths
The block diagram shows FLEX BUS power at 5 V DC and an external 24 V DC supply. The specified current requirements are less than 80 mA and less than 40 mA respectively. Verify both paths against the installed drawing before returning the station to service.
Module and channel indicators
A green/red status indicator distinguishes normal and abnormal module conditions. Eight yellow indicators show output ON states; unlit indicators show OFF states. The documented self-diagnostic functions include watchdog supervision, low power-supply voltage and bus timeout.
