Here are some key features of the 1756-OB16D module:

Digital Outputs: It has a total of 16 digital output channels. Each channel can sink or source current up to 0.5 amps at 24V DC.

Voltage Range: The module is designed to operate within a voltage range of 10...30V DC.

Output Type: The 1756-OB16D module uses solid-state outputs, providing reliable switching and fast response times.

Diagnostic LEDs: The module is equipped with status LEDs for each channel, enabling quick visual diagnostics for troubleshooting.

Module Communication: It connects to the ControlLogix chassis via the backplane, allowing for seamless integration and data exchange with other modules in the system.

Configuration: The module can be configured using RSLogix 5000 software, where you can set the channel properties, such as their output status, fault detection, and fault response.

Redundancy Support: The 1756-OB16D module supports redundancy in ControlLogix redundant systems, providing high availability and fault-tolerant operation.
