Product Overview
The 1791R-8B8P is a CompactBlock Remote I/O base module in the Allen-Bradley CompactBlock I/O 1791R series. It provides eight sinking inputs and eight sourcing outputs, enabling localized digital I/O interfacing via Remote I/O link. Installed in distributed control systems, it allows placement close to field devices-minimizing wiring runs and easing maintenance. Typical applications include machine-level I/O distribution in OEM equipment, conveyor systems, and remote sensing/actuation where space is limited.
Best Suited For
- Distributed I/O near sensors and actuators
