FX5-16EX/ES Mitsubishi 24VDC 16-Point PLC Input Module

Description

Mitsubishi FX5-16EX/ES is a 16-point digital input expansion block measuring 40 mm x 90 mm x 83 mm, operating at a nominal 24 VDC with a 4.0 mA input signal current. The hardware features a sink/source selectable input configuration with a 5.6 kΩ input impedance and utilizes a photo-coupler insulation circuit for signal isolation. Physical connections are established via an M3 screw terminal block, while the internal circuitry draws 100 mA at 24 VDC and 85 mA at 5 VDC from the host PLC. The module delivers a rapid input response time of 50 μs or less for ON signals and 150 μs or less for OFF signals, housed in an IP20-rated enclosure weighing 0.2 kg.
