Auxiliary relays INSTANTANEOUS RELAYS Plug-in relays with output contacts that switch instantaneously from their non-working position to working position when the coil is fed; the contacts return to their initial non-working position when the coil is no longer fed. Our standar relays are equipped with 2, 4, 8 and 16 inverted contacts ( models RD-2, RF-4, RJ-8, RI-16) as standard relays. This range is complemented with: Relays with free wheel diode, parallel to the coil, models RD-2DI, RF-4DI, RJ-8DI; Trip relays, models RD-2R, RF-4R, RJ-8R; Relays with seismic characteristics, models RD-2SY, RF-4SY, RJ-8SY; Relays with seismic characteristics, and diode parallel to the coil, models RD-2SYDI, RF-4SYDI, RJ-8SYDI- All the 2, 4 and 8 contact relays can be supplied with LED or mechanical indicators, trip flag, with a high breaking capacity and push-to-test button for cable checking.
