Specification

The Allen-Bradley 1746-OB16E is a robust 16-point DC output module designed for the SLC 500 programmable controller family. Engineered for demanding industrial environments, this module provides 24V DC sink/source outputs with built-in protection against overcurrent and short circuits. The 1746-OB16E is a direct replacement for older modules and offers seamless integration into existing SLC 500 systems, supporting both 24V DC and 5V DC logic levels. Its compact design and high-density output channels make it ideal for controlling solenoids, relays, and indicator lights in discrete manufacturing, process control, and material handling applications. Each output is optically isolated from the backplane, ensuring noise immunity and reliable operation in electrically noisy environments.
