USED MITSUBISHI QX80

The Mitsubishi Electric QX80 is a 16-point DC digital input module from the MELSEC-Q Series (QnU) programmable controller platform. It accepts 24V DC sink-type (minus common) input signals from external devices such as sensors and switches, and transmits them to the system CPU via photocoupler isolation. The module features a configurable response time and mounts directly to the Q-Series base unit using a snap-in mounting lever, with wiring via an 18-point screw terminal block.
