Short Description
Description:
The 1756-OW16I is a 16-point digital relay output module for the ControlLogix system, including individually separated electromechanical relay connections.
Each output channel may handle AC or DC loads, making this module perfect for controlling devices such as solenoids, motor starters, indicator lights, and other field actuators.
What distinguishes the 1756-OW16I is its separate isolation per channel, which improves safety and noise immunity in mixed voltage settings.
The module supports Form A (usually open) relay contacts and has LED indicators for each output, which provide clear status feedback.
This module is particularly beneficial in applications that need physical separation of outputs or where electrical isolation is crucial to system integrity.
