Allen Bradley 1719-A22 Ex I/O Base Chassis – 22-Slot POINTBus Backplane, 18–32V DC, DIN Rail Mount

The Allen Bradley 1719-A22 is a 22-slot Ex I/O base chassis designed for large-scale distributed I/O systems within hazardous and industrial automation environments. As part of the Allen Bradley Ex I/O series, this chassis provides a robust foundation for connecting analog, digital, and function modules through the POINTBus backplane, supporting high-density I/O configurations with exceptional reliability.

Operating on an 18–32V DC power supply, the 1719-A22 enables flexible expansion for Ex-rated systems and allows integration of multiple signal types within one modular platform. Its DIN rail mounting and industrial-grade construction make it ideal for complex control installations that require both performance and scalability.
