Allen Bradley 1790-T0B16X CompactBlock LDX I/O Expansion Block

Product Introduction

The Allen-Bradley 1790-T0B16X CompactBlock LDX I/O Expansion Block is a compact digital output expansion module designed to extend the output capacity of CompactBlock LDX systems. Developed by Rockwell Automation under the Allen-Bradley family, this module is widely used in distributed industrial control applications where additional output channels are required.

This expansion block provides 16 sourcing digital output channels operating at DC voltage levels, enabling reliable control of field devices such as relays, solenoids, and indicator lights. Designed as an open-style module with IP20 protection, it is suitable for installation inside control panels or protected enclosures.

With its compact size and seamless integration capability, the 1790-T0B16X allows users to scale their I/O systems efficiently without increasing system complexity.
