Allen Bradley 1790-T8BV8BX CompactBlock LDX I/O Expansion Block

Product Introduction

The Allen-Bradley 1790-T8BV8BX CompactBlock LDX I/O Expansion Block is a mixed digital I/O expansion module designed to extend both input and output capabilities in CompactBlock LDX systems. Developed by Rockwell Automation and released under the Allen-Bradley series, this module is tailored for distributed automation environments where flexible signal handling is required.

The module integrates 8 digital inputs (sinking/sourcing compatible) and 8 digital sourcing outputs, all operating on standard industrial DC levels. With DeviceNet communication support, it enables efficient integration into networked control systems while maintaining reliable real-time signal exchange.

Its compact open-style structure with IP20 protection allows installation inside control cabinets, making it suitable for machine-level automation and OEM equipment where space and flexibility are critical.
