Weidmüller DRI314730LT Relay Technical Guide
The Weidmüller DRI314730LT miniature industrial relay is a compact D-SERIES relay engineered for switching, amplifying, and multiplying digital signals in industrial control cabinets where space, clarity, and serviceability are all important. Also known as Weidmüller 7760056320 relay, this model belongs to the 16 mm width DRI family and is especially relevant when a single changeover contact is enough but maintenance visibility remains a priority.
What the Weidmüller DRI314730LT is
The Weidmüller DRI314730LT is a miniature industrial relay with 1 CO contact, AgSnO contact material, a 230 V AC rated control voltage, and a 5 A continuous current rating. It uses flat blade connections and includes both an LED and a test button. This specification makes it particularly useful for compact switching tasks that still benefit from direct visual status indication and manual testing capability.
The relay is intended for low electrical load digital signal applications and supports a small, efficient design approach. In dense cabinet layouts, that compact form factor is often a decisive advantage.
Why the single CO layout is still highly relevant
The Weidmüller DRI314730LT industrial relay uses a single changeover contact, which fits a very broad range of industrial tasks. Many control functions do not require multiple contact paths. They require one reliable switching path, clear integration, and predictable service behavior. That is exactly where this relay performs well.
Searches for Weidmüller DRI314730LT relay, Weidmüller 7760056320 miniature industrial relay, and Weidmüller 230 V AC 1 CO relay are common because buyers often need that exact balance of voltage, contact layout, and maintenance features.
Why the LED and test button make a difference
In an industrial maintenance context, the LED and test button are highly practical. The LED offers immediate operating status feedback. The test button supports manual actuation during startup, diagnostics, and service checks. For technicians working under time pressure, these features can reduce uncertainty and accelerate fault localization.
This makes the Weidmüller DRI314730LT miniature industrial relay more than a simple switching device. It becomes an easier component to manage over the full life of the installation.
Typical applications
The Weidmüller 7760056320 relay is suitable for industrial automation, machine control, signal interface assemblies, HVAC control systems, and utility-related control cabinets using 230 V AC logic. It is especially valuable where a compact relay with one changeover contact can perform the needed function without adding unnecessary complexity.
As part of the D-SERIES ecosystem, it also fits well into standardized relay-and-socket strategies that make replacement easier and help maintain cabinet consistency.
Selection guidance before use
Before choosing the Weidmüller DRI314730LT, engineers should verify coil voltage, current requirement, contact arrangement, and socket compatibility. It is also worth considering whether manual test capability is important for the service concept of the equipment. In many real installations, that feature becomes valuable sooner than expected.
