The Allen-Bradley 1791D-0B16PX is an output expansion module from the CompactBlock I/O 1791D series, featuring 16 sourcing-type output channels. It can be installed on a base input module with 16 inputs to produce 3 input bytes and consume 2 output bytes, on a base output module with 16 outputs to produce 1 input byte and consume 4 output bytes, or on a base combination I/O module to produce 2 input bytes and consume 3 output bytes. The module is compatible with SoftLogix, PLC, and SLC programmable controllers, providing flexible integration for industrial automation systems. In North America, Europe, and Asia, the 1791D-0B16PX may possibly enhance output expansion capabilities and could potentially be deployed across the globe, making it an essential component for professional industrial automation and DeviceNet connectivity.
