Coupling relays are used for indirect separation of the control and main circuits. Switching signals and input signal can be coupled in spite of different voltages. Coupling relays adapt the power during transmission by means of electrical separation. That means that it is for example possible that a 24 V signal controls a 230 V machine.
Application of relays in industry
Relays are used in all fields of industry. They are especially often used for the following tasks:
- Signal separation
- Signal fan-out
- Signal amplification
Coupling relays in the Automation24 online shop
Automation24 carries pre-assembled coupling relays from Phoenix Contact whose push-in connection is very easy to handle to allow easy wiring. They are available with an input voltage of 24 V DC: coupling relay PHOENIX 2903308 - RIF-2-RPT-LDP-24DC/4X21 and 230 V AC: coupling relay PHOENIX 2903304 - RIF-2-RPT-LV-230AC/4X21. The matching accessories, the timer module PHOENIX 2902647 - RIF-T3-24UC, allow to extend the 24 V coupling relay to create a timer relay in no time.
At Automation24 you find a large selection of coupling relays at very favourable prices. Select the coupling relay suitable for your application now!
