Weidmüller TRS 230VUC 1CO Relay Module Guide
The Weidmüller TRS 230VUC 1CO relay module is a TERMSERIES interface product created for industrial switching and control applications that require galvanic isolation and a clean, serviceable installation concept. Also identified as Weidmüller 1122820000 relay module, this version combines a plug-in relay and socket assembly and is specified with 1 CO contact AgNi, a 230 V UC ±10% rated control voltage, a 6 A continuous current rating, and screw connection. The official listing also notes that a test button is not available on this version.
Why the Weidmüller TRS 230VUC 1CO matters in control design
Single-contact relay modules remain highly relevant because many control tasks only need one dependable changeover path. The Weidmüller TRS 230VUC 1CO relay module fits that role in machine panels, automation cabinets, building services controls, and process interfaces where 230 V universal control voltage is already part of the system. Its modular structure also supports quick replacement and more consistent project standardization.
Technical strengths in practical use
This module’s 1 CO AgNi contact layout makes it a good fit for signal transfer, interposing, and compact command switching. The screw connection format supports reliable conductor termination and remains familiar to many electricians and panel builders. Since the control circuit and load circuit are electrically isolated, the module helps create cleaner and more robust control architecture, especially where signal integrity and interface safety are priorities.
Where it is commonly used
The Weidmüller 1122820000 relay module is commonly applied in control cabinets, utility systems, industrial signaling, and OEM equipment where one changeover contact is sufficient. Engineers who search by the full product name are usually aiming to match not only the contact count, but also the exact connection style and control voltage. That precision helps avoid mismatched replacements and unnecessary redesign work.
Selection notes before ordering
Before specifying the Weidmüller TRS 230VUC 1CO relay module, users should check the required coil voltage, contact arrangement, current level, and whether the lack of a test button aligns with the maintenance concept of the installation.
