Mitsubishi AJ55TB32-8DR Relay Output Module for MELSEC FX Series

The Mitsubishi AJ55TB32-8DR (AJ55TB32-8DR) is a 16-point digital relay output terminal block module designed for use with Mitsubishi Electric MELSEC-F FX series programmable logic controller systems. Serving as an expansion unit and wiring interface, this digital output module provides reliable switching control between the central processing unit and external field devices. It features sixteen normally open relay contact outputs, functioning equivalently to the FX16EYRESTBUL terminal block unit to streamline high-density control cabinet wiring and peripheral connections. Engineered for industrial automation and machinery control, the module simplifies field signal distribution by combining modular terminal connectivity with robust relay outputs. Each channel operates independently with normally open contacts to actuate external loads such as solenoids, indicator lamps, intermediate relays, and motor starters across manufacturing lines, packaging machinery, and material handling systems. The unit allows clean and secure terminal connections while maintaining dependable electrical isolation between control logic and field actuators.
