Allen-Bradley 1746-OB16 16-Point DC Output Module

Allen-Bradley 1746-OB16 is a 16-point DC sourcing output module for the SLC 500 family, delivering 24 V DC outputs at up to 0.5 A per point within a 10–50 V DC operating range. Designed for the 1746 I/O chassis, it provides sixteen independent outputs that source current to energize loads such as relays, coils, or valve actuators, with a total continuous current rating of 8 A per module at 30 °C. Each channel is rated to 0.5 A, allowing direct drive of multiple low- to medium-current 24 V devices from a single module. The 10–50 V DC range accommodates nominal 24 V control systems with headroom for voltage dips and brief surges common in industrial environments. This DC Output module is a classic component of Rockwell Automation’s SLC 500 platform, occupying a single slot in the 1746 I/O rack and wiring through field connections. Typical applications include control of conveyors, actuated valves, lights, indicator signals, and other 24 V DC actuators where a compact, multi-channel output solution is required.
