Here are some key features of the 1756-OW16I module:

Digital Outputs: It offers 16 digital output channels, which are isolated from the backplane and designed to control high-current loads.

Output Type: The module supports relay output type, meaning it can provide both normally open (NO) and normally closed (NC) contacts.

Current Rating: Each output channel can handle a maximum current of 1.4 A at 30 V DC. It is essential to ensure that the connected devices do not exceed this current rating.

Diagnostic LEDs: The module features diagnostic LEDs for status indication such as module health, output status, and fault conditions.

Compatibility: The 1756-OW16I module is compatible with the ControlLogix chassis platform and can be installed in any available slot of the chassis.

Configuration: The configuration of the module is performed using software programming tools such as RSLogix 5000 or Studio 5000. The user can specify the functionality, addressing, and behavior of each output channel through the software.
