Product Overview
The 1794-OB16PXT is an Allen-Bradley Flex I/O-XT series 16-point digital output module, designed to source 24 V DC outputs within a distributed I/O control system. It provides electronically protected sourcing outputs and integrates into Flex XT platforms via compatible terminal bases. Typical use cases include discrete control signals for actuators, valves, and pilot devices in extended-temperature industrial environments. The module supports extended ambient conditions, suitable for on-machine or process installation, and works alongside other Flex I/O-XT components. Part number appears as 1794-OB16PXT.
