PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-OV16 is a discrete output module designed for the SLC 500 modular system. It features sixteen sinking output channels arranged in a single common channel group. The unit operates within a voltage range of 10 to 50 VDC with 24 VDC nominal voltage. It energizes DC loads including relay coils, indicator lamps, and sounding devices. The module draws 0.270 A of backplane current at 5 VDC.
This single-slot module mounts directly into an SLC 500 modular chassis. A pre-installed removable terminal block allows field wiring to detach during maintenance. Continuous output current reaches 0.50 A per point at 30 °C and 0.25 A at 60 °C. Continuous current per module is 8.0 A at 30 °C and 4.0 A at 60 °C. Total module heat dissipation is 7.6 W, with 0.388 W dissipated per point.
