25 relay outputs Switches AC or DC loads 120V rating Electrical isolation For SLC 500 systems Reliable switching

Product description

The Allen Bradley 1746-RT25R is a 25-point terminal relay output module for the SLC 500 programmable logic controller system. It allows the PLC to switch AC or DC loads up to 120V. This module provides electrical isolation between the PLC logic and the field devices.

This relay module is commonly used in applications requiring the PLC to control higher voltage or current devices, such as motors, lights, or solenoids, where direct PLC output is not suitable. Industries that utilize the SLC 500 platform, including manufacturing, building automation, and material handling, benefit from the flexibility of this module.

Stanlo Automation, a veteran-owned distributor of surplus automation parts, offers the 1746-RT25R to help you maintain your existing SLC 500 systems. We understand the importance of reliable components for uninterrupted operations.
