Mitsubishi Electric QX42-S1 DC Output Module Unit

The Mitsubishi Electric QX42-S1 DC Output Module provides four 24 VDC digital outputs for Mitsubishi Q-Series PLCs. Mounted in a PLC rack slot or on DIN rail (system dependent), it wires to field devices such as relays, solenoids, and indicator lamps via field terminals. Outputs can be configured as sourcing or sinking (platform dependent) with per-channel current rating and overload/short-circuit protection where supported, and status LEDs indicate output activity. Common replacements include Mitsubishi QX42-S, Omron SYSMAC DC output module, and Allen-Bradley 1734-OB4; it is designed for factory and process automation environments requiring reliable DC output control and operates within industrial temperature ranges.
