FX5-16EX/ES 16‑Point Digital Input Module 24V DC Sink/Source | Mitsubishi

The Original New Mitsubishi FX5‑16EX/ES is a 16‑point digital input module for the MELSEC iQ‑F series, designed to expand the input capacity of FX5U, FX5UC, FX5UJ, and FX5S CPU modules. It provides 16 digital inputs configurable for sink or source (PNP/NPN) operation, accepting 24V DC signals from sensors, switches, and pushbuttons. The screw‑clamp terminal block ensures secure and reliable field wiring. Photocoupler isolation between inputs and internal circuits ensures reliable signal acquisition in industrial environments. With 16 occupied I/O points on the PLC, this module enables seamless system expansion for machine automation, conveyor control, and factory automation applications.

Core Engineering Highlights:
16 digital inputs (24V DC, sink/source configurable) | 5.6 kΩ input impedance | 4 mA input current at 24V DC | 50 µs ON / 150 µs OFF response time | Photocoupler isolation | Screw‑clamp terminal block | 16 occupied I/O points | 100 mA @ 5V DC + 85 mA @ 24V DC consumption | 40 × 90 × 83 mm | 0.2 kg | 0°C to 55°C operating temperature
