The Allen-Bradley 1756-OB16E discrete output module is a key component of the ControlLogix Programmable Automation Controllers platform, providing reliable DC output for actuating 24VDC-rated devices. It features 16 output channels divided into two electronically-fused groups of eight, supporting applications that include relay coils, solenoids, and pilot lamps. Designed for seamless integration with any 1756 ControlLogix rack and compatible enclosures such as the 1756-A4 and 1756-A17, this module handles an output voltage range of 10-31.2 VDC and delivers up to 1A per channel or 8A per module at 60 °C. The 1756-OB16E offers superior performance with fast response times, a surge current capability of 2A for 10 ms per point, and low power dissipation, making it an efficient choice for high-demand industrial environments.
