C4 series

General-purpose industrial electromechanical relay

LED indicator
built-in polarity & freewheeling diodes
power type
Built-in freewheeling diode dampens transients caused by the relay coil on de-energisation.
Built-in diode in series with the coil protects the relay from reverse connection

Product range
ComatReleco offers a wide range of relay types and versions and associated sockets and accessories.

Industrial Relays C2‚ C3‚ C4‚ C5
35 x 35mm round plug-in relay‚ 8- or 11-terminals multipole connector according to IEC 67 with 2 or 3 contacts up to 10A and different contact types and contact materials.

Standard relay 35 x 35mm with flat blade connectors with up to 4 contacts and up to 16A with 3 contacts.
Special relays and remanence relays
While "normal" relays are monostable‚ they return to the idle state when the excitation is switched off. Remanence relays are bistable.
The current switching state is retained irrespective of the excitation.
Relays of this type are available in different versions.

Accessories
Suitable sockets are available for the different relay series for DIN rail mounting or panel mounting.
In addition retaining clips are available for the relays and some of which are included in the scope of supply.
Suitable bridges for cost-saving wiring in series are also available.
