Allen-Bradley | 1794-IB16XOB16P | FLEX I/O (1794 Series)

Product Description: Allen-Bradley 1794-IB16XOB16P

The Allen-Bradley 1794-IB16XOB16P is a 32-point combination digital I/O module within the FLEX I/O platform. It integrates 16 sinking (NPN) digital inputs and 16 sourcing (PNP) digital outputs into a single compact module, ideal for systems requiring both input monitoring and output control in limited space. The sourcing outputs are electronically protected against short circuits and overcurrent, enhancing reliability in industrial environments.
