PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-OB16 is a 16-point DC sourcing output module designed for the SLC 500 system. This module provides a nominal voltage category of 24V DC for industrial signal outputs. The operating voltage range spans from 10V DC to 50V DC across its single output group. It draws 0.28 Amps at 5V DC from the backplane and zero current at 24V DC.
Thermal management requires a minimum module heat dissipation of 1.4 watts during normal chassis operation. Individual output points dissipate 0.388 watts, producing a maximum total output heat dissipation of 7.6 watts. The unit provides fast switching speeds with a 0.1 millisecond turn-on delay under resistive loads. Turn-off delay is rated at 1 millisecond under maximum resistive conditions. A removable terminal block simplifies wiring connections and module replacement.
