Allen-Bradley 1756-OB16I ControlLogix 16-Point Isolated Digital Output Module
Product Overview
The Allen-Bradley 1756-OB16I is a high-performance digital output module belonging to the ControlLogix® I/O family. Engineered for applications requiring superior signal integrity, this module features 16 fully isolated output channels. The "I" designation signifies that each point is electrically separated from the others, preventing cross-channel interference and providing a robust barrier against field-side electrical surges.
This sourcing module operates within a 10–30 VDC range and is capable of driving high-current loads, including solenoids, large contactors, and pilot lamps. Its isolated architecture makes it an essential choice for complex control systems where different outputs may be powered by separate power sources or where safety-critical isolation is mandatory to protect the controller backplane.
