Allen Bradley 1790D-T32BV0 DeviceNet LDX I/O Universal Input Base Module

Product Introduction

The Allen-Bradley 1790D-T32BV0 DeviceNet LDX I/O Universal Input Base Module is a compact distributed I/O module designed for industrial automation systems that utilize DeviceNet communication. Developed by Rockwell Automation under the Allen-Bradley product family, this module belongs to the CompactBlock LDX series and is intended to provide efficient signal acquisition at the machine level.

The module integrates 32 universal digital input channels in a compact housing, allowing a large number of field devices to be connected within a limited panel space. It operates with a 24 VDC power supply, which aligns with standard industrial control systems and ensures stable operation in typical automation environments.

Designed for distributed I/O architecture, the 1790D-T32BV0 allows sensors and switches to be connected close to the equipment being monitored. This approach helps reduce long wiring runs and simplifies installation inside machine control panels. With its compact construction and integrated terminal connections, the module provides a practical solution for digital signal acquisition in modern factory automation systems.
