Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1790D-T8BV8V is an Allen-Bradley CompactBlock LDX I/O DeviceNet input/output base terminal block combining eight universal sinking or sourcing inputs and eight sinking outputs. It functions as an expansion module within CompactBlock LDX distributed I/O systems, interfacing via DeviceNet. It is typically deployed in industrial settings such as machine control panels, material handling systems, and modular automation architectures for discrete signal processing. The 1790D-T8BV8V is designed to supplement a base I/O station when additional I/O capacity is required.
