Mitsubishi Electric QX80 Digital Input Module

The Mitsubishi Electric QX80 Digital Input Module provides 16 DC input points for fast, discrete signal acquisition from field devices into MELSEC-Q Series PLCs. Designed for rack-mounted use in the Q Series base unit, it features a terminal block connection and uses backplane communication to share power and data with the PLC. Key specifications include a 24V DC rated input voltage, DC digital input type, and high-speed input processing to capture sensor and switch state with minimal latency. Common applications include assembly lines, conveyors, packaging machines, and process control systems in industrial environments where reliable discrete signals must be monitored and acted upon. Power is supplied via the PLC base unit, and the QX80 remains compatible with MELSEC-Q Series backplanes; common replacements include QX40, QX41, and QX81.
