Product Introduction
The Allen-Bradley 1746-OB16 is a digital DC output module designed for the SLC 500 programmable controller platform. It provides reliable control of DC-powered field devices in industrial automation systems where stable switching performance and predictable electrical behavior are required.
This module offers 16 independent DC output points, enabling high output density within a single SLC 500 I/O slot. Operating within a 10–30 VDC voltage range and supporting a total output capacity of 8 A, the 1746-OB16 is suitable for driving solenoids, relays, indicators, and other DC loads commonly found in industrial control panels.
Built for continuous industrial operation, the 1746-OB16 emphasizes electrical robustness, consistent output behavior, and seamless integration with SLC 500 processors. Its design supports efficient wiring practices and dependable long-term operation in both new installations and legacy control systems.
