It features sixteen sourcing output points organized into a single group and powered directly through the SLC backplane, requiring no external power supply for operation. Each output channel can supply up to 1.5 A at 30 °C (1.0 A at 60 °C), enabling control of a wide range of industrial loads. This module supports fast switching, featuring an ON-to-OFF delay of 0.1 ms and an OFF-to-ON delay of 1.0 ms, making it suitable for both standard and high-speed applications. It provides optical isolation between the backplane and output circuitry, tested at 1500V AC, ensuring reliable operation in electrically noisy environments. Key Features: Sixteen (16) sourcing 24 VDC output channels Single output group; no individual isolation Operating voltage range: 10–30 VDC ON/OFF switching delays as fast as 0.1–1.0 ms Optical isolation from backplane Backplane-powered—no external supply required Output current per point: up to 1.5 A (30 °C) Output current per module: up to 6.4 A LED status indication for each output Compatible with all SLC 500 chassis and remote I/O setups The Allen-Bradley 1746-OB16 is a reliable digital output solution for controlling DC-powered field devices in SLC 500 automation systems. With high current capacity and fast switching response, it is well suited for machine control, discrete manufacturing, packaging, conveying systems, and building automation. It offers long-term durability and easy integration into existing SLC architectures.
