Electronic relays

Measuring relays

Measuring relays are an excellent alternative to digital protection systems to minimise – or even rule out – not only the effects of electrical faults in switchboards, wiring or transformers, but also any risk to individuals. Measuring relays ensure quick and selective error detection and can potentially trigger a shutdown to facilitate the continued operation of uninterrupted networks. What’s more, applications with the corresponding scope of device technology can also still be implemented at a considerably lower cost.

Time relays

The electronic time relay of the 22.5 mm series can be used in all control technology for implementing time-delayed switching processes in starting, control and monitoring systems.
This involves special single-grade, single-function and multi-grade multifunctional time relays.

Time relays with different functions are supplied for various voltages and time frames:

• Response delay
• Release delay with/without auxiliary voltage
• Pulse on operate
• Impulse generator 1:1 pause/pulse begin
• Y – ∆ – switching
• Multifunctional timer
