Allen-Bradley 1756-OW16I ControlLogix Isolated Relay Output Module
Description
The Allen-Bradley 1756-OW16I ControlLogix Isolated Relay Output Module is a digital relay output unit belonging to the ControlLogix series, designed for industrial automation control systems. It converts digital signals from ControlLogix systems into AC voltage signals required by external devices, enabling reliable control of both AC and DC loads such as motor starters, contactors, valves, and indicator lights. Key specifications include 16 isolated Form C (single-pole double-throw) relay output channels, with each channel supporting a maximum load current of 2A. The module operates on a voltage range of 74 to 265V AC, with a nominal working voltage of 120/240V AC, making it adaptable to diverse industrial power environments. Its isolated design provides electrical separation between outputs and the control system, as well as between individual channels, enhancing system stability and resistance to electrical interference. Additional features include built-in module and point status diagnostic capabilities for efficient fault detection and maintenance, full integration with ControlLogix systems for configuration and monitoring via Logix 5000 controllers, and support for communication protocols such as ControlNet and EtherNet/IP. It is ideal for applications including production line automation, mechanical equipment control, and process management, where high reliability and discrete output control are required.
