Weidmüller TRZ 230VUC 1CO Relay Module Guide
The Weidmüller TRZ 230VUC 1CO relay module is a TERMSERIES product created for industrial control systems that need a compact relay interface with fast and reliable conductor handling. Also listed as Weidmüller 1122930000 relay module, it is specified with 1 CO contact AgNi, a 230 V UC ±10% rated control voltage, a 6 A continuous current rating, and a tension-clamp connection. The official product information also states that a test button is not available.
Why the tension-clamp design matters
The defining difference of the Weidmüller TRZ 230VUC 1CO relay module is its tension-clamp connection method. In cabinet production and industrial panel assembly, tension-clamp technology is often preferred for faster installation, consistent wire retention, and repeatable wiring quality. That makes this product particularly attractive in projects where production efficiency and standardized wiring practice are major priorities.
Technical role in control systems
With 1 CO contact and a 230 V UC coil, the module is positioned for single-path switching, interface isolation, and compact control tasks. The official description notes that the assembly consists of a plug-in relay and a plug-in socket, and that the control and load circuits are electrically isolated. In practical terms, that makes the Weidmüller 1122930000 relay module a reliable option for signal interfacing, machine control, and utility applications where galvanic separation is important.
Typical applications
The Weidmüller TRZ 230VUC 1CO is suitable for industrial automation, building systems, machine panels, and interface cabinets that use universal 230 V control logic. The lack of a test button can be perfectly acceptable in installations where manual actuation at relay level is not part of the maintenance routine.
