Product Description
The Mitsubishi Electric QX40 is a 16-point DC digital input module designed for the MELSEC-Q Series programmable logic controller platform. It accepts 24V DC on/off signals from external devices such as sensors, switches, and proximity inputs, converting them into internal PLC logic for machine control applications. The module features optical (photocoupler) isolation on all input points, a shared 16-point common in sink-type configuration, per-point LED status indicators, and an 18-point removable screw-terminal block for secure industrial wiring.
