RX40C7 16-Point Digital Input Module 24V DC MELSEC iQ-R | Mitsubishi

The Original New Mitsubishi RX40C7 Digital Input Local Unit Module is a 16-point DC input module from the MELSEC iQ-R series, designed for reliable signal acquisition from field devices in industrial automation systems. It accepts 24 V DC input signals with a rated input current of 7.0 mA and supports a wide configurable response time range from 0.1 ms to 70 ms, allowing adaptation to different sensor and application requirements. The module features a positive/negative common shared wiring configuration, providing installation flexibility, and is equipped with an interrupt function that can be configured via module parameters. The unit connects to the backplane/rack via an 18-point screw-clamp terminal block and is rated IP2X for protection against finger contact.
