Allen-Bradley 1790-T0W8X 8-Channel Relay Output Expansion Module
Product Description
The Allen-Bradley 1790-T0W8X is a flexible 8-point relay output expansion module for DeviceNet systems. It features Form A (SPST-NO) relays that can switch a wide range of AC/DC voltages, making it ideal for mixed-load applications like lights, small motors, and solenoids. This compact module provides high electrical isolation and is designed for reliable expansion of your control system.

Installation & Wiring Guide
This is an expansion module and requires a base module for DeviceNet communication. Connect the 24V DC field power within the 19.2-28.8V DC range. Wire loads directly to the terminal block using copper conductors. Tighten screws to a maximum of 7 lb-in. Ensure loads do not exceed the specified current ratings for the chosen voltage.
System Compatibility
Designed as an expansion block for the Allen-Bradley 1790 ArmorBlock MaXum DeviceNet I/O system. Must be connected to a compatible 1790 series base module. Perfect for adding versatile relay outputs to control mixed AC/DC loads from a single network node.
