Weidmüller TRZ 24VUC 1CO Relay Module Overview
The Weidmüller TRZ 24VUC 1CO relay module is a compact TERMSERIES product designed for switching and interface applications where flexible control voltage support and reliable connection technology are both important. Also identified as Weidmüller 1122890000 relay module, this module is suitable for industrial control systems that use universal current characteristics and need an efficient relay interface within a slim installation footprint.
What the Weidmüller TRZ 24VUC 1CO is
The Weidmüller TRZ 24VUC 1CO is a TERMSERIES relay module with 1 CO contact, AgNi contact material, a 24 V UC ±10% rated control voltage, and a 6 A continuous current rating. It uses a tension-clamp connection and does not include a test button. This technical profile makes the module attractive where quick, reliable conductor handling and compact relay integration are priorities.
The universal current characteristic is especially important. In certain control strategies, that broader flexibility can simplify specification and help align the product with more diverse system requirements.
Why tension-clamp connection can be a strong advantage
The Weidmüller TRZ 24VUC 1CO relay module uses a tension-clamp connection, which is highly relevant in modern panel building. Tension-clamp technology supports fast installation, consistent conductor retention, and efficient repeatability in production-oriented cabinet assembly. For teams that build multiple cabinets or rely on streamlined wiring processes, this can be a clear operational benefit.
In service terms, tension-clamp solutions also contribute to cleaner connection management. That makes the module a practical choice for applications where installation speed and connection reliability both matter.
Where the 24 V UC concept fits
The 24 V UC rating gives the Weidmüller TRZ 24VUC 1CO a flexible position in relay module selection. It can be relevant in applications where engineers are working within broader control-voltage expectations and want a solution aligned with universal current usage. In technical sourcing, that specificity matters, which is why searches for Weidmüller TRZ 24VUC 1CO relay module and Weidmüller 1122890000 relay are typically exact and deliberate.
Typical industrial applications
The Weidmüller 1122890000 relay module is suitable for automation cabinets, machine control systems, decentralized I/O interfaces, process-support panels, and general industrial signal switching. With a single changeover contact and a 6 A current rating, it fits command transfer, interface isolation, signal routing, and compact control functions.
Because it belongs to the TERMSERIES range, it also supports structured relay standardization. That can reduce spare-part complexity and make project documentation easier to maintain across larger system fleets.
Points to review before specification
Before choosing the Weidmüller TRZ 24VUC 1CO relay module, engineers should confirm the required control voltage characteristics, connection method, contact arrangement, and expected load. Since this version has no test button, it is also useful to consider whether manual actuation is important in the maintenance concept of the machine or cabinet.
