Discontinued Source-Output Remote I/O Unit
Mitsubishi FCUA-DX111, also identified in searches as FCUADX111, is a discontinued remote I/O unit for machine digital signals in supported Mitsubishi CNC configurations. Its source-output circuit is a key replacement characteristic and should be checked together with the complete model number.
Verified 64DI/48DO Hardware Configuration
Mitsubishi documentation identifies the FCUA-DX111 hardware as RX312 + RX322-1. It provides 64 photocoupler-isolated digital inputs supporting 24V/0V common selection, 48 non-isolated source-type digital outputs and two occupied remote I/O stations.
Understanding the 1.5A and 30W Ratings
The documented input power requirement is 24VDC ±5%, with a required power capacity of 1.5A for the control circuit. The listed 30W value is the maximum heating value, which varies according to the number of active machine-input points and the load connected to the machine outputs.
Why FCUA-DX111 Is Not the Same as FCUA-DX110
Both models provide 64 inputs and 48 outputs, but their output circuits differ. FCUA-DX111 uses source-type outputs and RX312 + RX322-1 hardware, whereas the Mitsubishi FCUA-DX110 remote I/O unit uses sink-type outputs and RX311 + RX321-1 hardware. Matching only the I/O count can therefore result in the wrong replacement.
Replacement Checks for Existing CNC Machines
Confirm the FCUA-DX111 label, source-output requirement, RX312 and RX322-1 configuration, 24VDC supply, station setting, machine wiring and DI-L, DI-R, DO-L, DO-R, RIO1 and RIO2 connections before ordering.
Send REACO CNC clear photos of the complete model label, front connectors and installed remote I/O assembly. Visible identifiers can be compared before condition, stock, price and lead time are confirmed.
