Product details

CPU Module for 80-Point Relay Output Systems

The Mitsubishi FX5U-80MR/DS is a CPU module from the MELSEC iQ-F series with 80 total I/O points — 40 inputs at 24 V DC (sink) and 40 relay outputs. It uses a screw terminal block for field wiring, keeping your existing panel terminations consistent.

Comparison with FX5UC-64MT/D – What Changes

If your BOM was written around the FX5UC-64MT/D, note that the FX5U-80MR/DS is a different form factor — it uses a screw terminal block instead of a connector, and its 40 transistor outputs are replaced by 40 relay outputs. The transistor variant is usually for high-speed or DC loads; relay outputs handle AC/DC up to the contact rating but are slower. Panel wiring will need re-termination; the two modules are not drop-in interchangeable.

Frequently asked questions

Will the FX5U-80MR/DS drop into a panel designed for the FX5UC-64MT/D?

No. The FX5U-80MR/DS uses screw terminals and relay outputs, while the FX5UC uses a connector and transistor outputs. Panel rewiring and I/O reconfiguration are required.
