Relay type A = Standard (general-purpose) contact E = Sensitive drive with 500 mW coil power G = Refers to a NO contact H = Single-point contact + twin contact load to signal current circuit for switching state feed back. Mixed contact configuration M = Relay with highly effective neodimium blow magnet for fast quenching of the arc. This relay is particularly suitable for high DC loads. N = Sensitive drive 800mW coil power R = Code for remanence relays, drive-specific ID S = Sensitive drive with 250 mW exciter input T = Twin contact for signal and control circuit W = With tungsten contact for maximum switch-on currents |

Product range
Releco offers a wide range of relay types and versions and associated bases and accessories.
Standard (general-purpose) relay, MRC series
35 x 35 mm round plug-in relay, 8- or 11-terminals multipole connector according to IEC 67 with 2 or 3 contacts up to 10 A and different contact types and contact materials.
Standard relay 35 x 35 mm with flat blade connectors with up to 4 contacts and up to 16 A with 3 contacts.
Miniature industrial relay, QRC series
22.5 mm series with up to 4 contacts and up to 10 A with 1 or 2 contacts.
Interface relay, IRC series
Overall width 13 mm with up to 2 electromechanical contacts, or fully electronic switches.
Special relays, remanence relays
While "normal" relays are monostable, i.e. they return to the idle state when the excitation is switched off, remanence relays are bistable, i.e. the current switching state is retained irrespective of the excitation.
Relays of this type are available in different versions.
Electronic relay, CSS
In the IRC series different electronic DC or AC relays up to 3 A are available.
For AC relays a distinction is made between synchronously (zero crossing) and asynchronously switching versions.
For switching transformer loads we recommended using asynchronously switching semiconductor switches.
For incandescent lamp loads etc. synchronously switching switches are ideal for avoiding high switch-on currents.
Accessories
Suitable bases are available for the different relay series for DIN rail mounting or panel mounting.
In addition, retaining clips are available for the relays, some of which are included in the scope of supply.
Suitable bridges for cost-saving wiring in series are also available.
