Allen-Bradley 1746-OB16/D Digital DC Output Module

Description

The Allen-Bradley 1746-OB16/D Digital DC Output Module is a dedicated component designed exclusively for the SLC 500 series programmable logic controller (PLC) platform, engineered to deliver reliable control in harsh industrial environments. It features 16 digital sink-type output points, enabling precise operation of a wide range of industrial actuators and devices. Key technical specifications include a 10-50V DC operating voltage range, a maximum 0.5A current per output point, and a 115mA backplane current draw at 5V DC. The module provides 1500V AC isolation between field and logic circuits to protect sensitive control electronics. It operates reliably at temperatures from 0 degrees Celsius to 60 degrees Celsius, with a storage temperature range of -40 degrees Celsius to 85 degrees Celsius, and meets UL, CE, and CSA safety and performance standards. Core features include high-speed output control for real-time industrial processes, a compact form factor that integrates seamlessly into any 1746 chassis for easy system expansion, and rugged output channels built for long-term stable operation. Typical applications include factory automation, production line control, process equipment management, and direct control of DC loads such as relays, solenoid valves, and small motors.
