A-B 1746-OB16 Digital DC Output Module

Allen Bradley 1746-OB16 Digital DC Output Module

This 16-channel DC output module serves as a critical interface between programmable logic controllers (PLCs) and field devices in industrial environments. Designed for SLC 500 systems, it delivers precise control for solenoids, relays, and indicator lights while maintaining robust performance in demanding conditions.

Commonly deployed in automotive assembly lines and food processing plants, this module handles tasks like conveyor belt control and safety interlock systems. We frequently see it integrated with SLC 500 processor units in packaging machinery applications where simultaneous control of multiple actuators is required.

The module’s dual isolation ratings (500VDC communication circuits and 1500VAC backplane) provide enhanced protection against electrical surges. Its low 1.2V on-state voltage drop maintains signal integrity even with fluctuating power supplies. While technically a SLC 500 series component, we’ve successfully integrated it with newer ControlLogix systems using appropriate interface modules.

With 4A total current handling and chassis mounting design, this module combines industrial durability with flexible installation options. The open-type enclosure suits standard control cabinets while maintaining adequate protection against dust accumulation in typical factory environments.
