What it is and where it lands
The Mitsubishi FX5UJ-24MR/ES is a compact PLC from the FX5UJ series, configured with relay outputs for small-scale industrial automation jobs, and it files under PLC Expansion Modules inside the PLCs & HMIs branch.
Function on the line
As a relay-output FX5UJ unit, it switches its discrete loads through mechanical contacts rather than transistors, which is the configuration usually picked for mixed-contact, low-cycle actuator and signal-routing work in a small panel — a transistor-only FX3GA sits on a different output topology, not on the same load curve.
