Allen-Bradley 1746-OV8 SLC 500 Output Module

Allen-Bradley 1746-OV8 is an eight-point SLC 500 DC output module that provides eight sinking outputs for discrete loads. Designed to operate from a 10 to 50 V DC supply with a 24 V DC signal output category, it sinks current from each load to the common return when energized. Each channel can deliver up to about 1 A, giving a total continuous module current rating of 8 A at 30 °C, while the backplane draws roughly 135 mA from the 5 V supply. This makes the OV8 suitable for driving relay coils, small DC solenoids, and other low-power DC loads directly from an SLC 500 controller. Installed in a 1746 backplane, the module communicates with the CPU through standard SLC 500 backplane signaling and pairs with other OV-series modules if higher I/O density is required. The device’s specifications identify eight independent DC sinking outputs, a 10–50 V DC operating range, and a 24 V DC signal level, making it a compact, scalable solution for automation tasks that require reliable, field-wirable discrete control of DC devices.
