Allen-Bradley 1746-0B16 SLC 500 Output Module

The Allen-Bradley 1746-0B16 is a 16-point DC output module for the SLC 500 system, delivering sixteen 24V DC outputs in a sourcing configuration to drive DC loads from a standard 1746 backplane. As a member of the 1746 SLC System, this module plugs into a compatible SLC 500 chassis to expand the controller’s digital output capability. The 1746-0B16 is listed by Rockwell as the 1746-OB16 variant of the family and, per official product lifecycle information, is discontinued as of September 30, 2024, with engineering replacement guidance available from Rockwell. This module provides discrete DC outputs controlled by ladder logic or program logic on the SLC 500 CPU, enabling straightforward control of 24V DC devices in industrial automation environments.
