FX3U-48MR/ES-A — Main Unit with 48 I/O, Relay Outputs
The FX3U-48MR/ES-A is a Mitsubishi FX3U series programmable controller main unit offering 48 I/O points — 24 digital inputs and 24 outputs, all relay type. Powered by 100-240V AC, it draws 40W and measures 182x90x86 mm for panel integration. Relay outputs handle AC/DC loads, suitable for general switching in automation lines where speed is less critical than isolation or voltage flexibility.
Sourcing & Lifecycle Reality
Lifecycle stage is mature. The FX3U-48MR/ES-A remains sourceable; quote to order via RFQ.
Why This Isn't a Drop-In for FX3S-30MT/ES
The FX3S-30MT/ES is a smaller, transistor-output unit (16 inputs, 14 outputs) — different series, different I/O mapping, different output technology. The FX3U-48MR/ES-A has 24 inputs / 24 relay outputs and a larger footprint (182x90x86 vs 100x90x75 mm). Rewiring and program conversion would be needed; not a physical or electrical swap.
