Relays are available in different forms – from modular terminal enclosures to plug-in bases for terminal rail mounting.
For switching and amplification of digital signals in automation engineering as well as for electrical isolation between control and load circuit.
The input voltages (coil voltage) lie between 5 and 230 V AC/DC depending on type. Different types of contacts such as NOC,
NCC and CO contacts are available at the output The use of different contact materials enables the switching of power ratings from just a few mW to max. 4 kVA.
