Allen-Bradley 1791D-0B16PX CompactBlock I/O DeviceNet Output Module
The 1791D-0B16PX is an Allen-Bradley CompactBlock I/O DeviceNet expansion module with 16 sourcing outputs operating at 24 VDC. It provides distributed output control through a DeviceNet network, allowing a PLC or machine controller to operate connected field devices through a remote I/O block. The manufacturer discontinued this model on June 30, 2013.
Product Overview
The 1791D-0B16PX belongs to the CompactBlock I/O product family and is designed for distributed digital output applications. Its 16 sourcing output channels provide switched DC output signals to compatible field loads.
As a DeviceNet expansion block, it connects output points to a networked control architecture rather than requiring every field signal to be wired directly to the central PLC rack.
Output Configuration
The module provides 16 sourcing outputs with a 24 VDC operating specification. Sourcing outputs supply positive voltage to the connected load when activated, so the field-device wiring must be compatible with this output arrangement.
The available specifications do not establish the maximum output current per channel, total module current capacity, or short-circuit protection characteristics. These values should be checked against the applicable technical documentation before selecting the module for a specific load.
DeviceNet Communication
DeviceNet provides the network communication interface between the output block and the controlling system. The controller can use the network to exchange output data with the distributed module, reducing the need for individual control wiring back to the main PLC enclosure.
The exact DeviceNet communication settings, supported data rates, node-address configuration, and network power requirements are not specified in the supplied information.
