Mitsubishi FX2N-64MR-ES/UL MELSEC-F 64-Point PLC 32 Inputs 32 Relay Outputs

Mitsubishi Electric MELSEC‑F FX2N‑64MR‑ES/UL is a compact programmable logic controller with integrated CPU, power supply and I/O. Provides 32 digital inputs (24 V DC, sink/source configurable) and 32 relay outputs (2 A per point, 4 independent common groups of 8 points each). Built‑in 100‑240 V AC power supply, 0.08 µs LD instruction execution speed, and 8,000‑step EEPROM program memory (expandable to 16,000 steps). Supports expansion up to 256 total I/O via FX2N extension modules. UL listed. This product is discontinued and available as a spare part for maintaining existing FX2N‑based automation systems.
