Power relays

Erni offers SEV-approved miniature power relays particularly suited for high switching loads on PCBs. The relay is mounted in a transparent plastic-sealed case, leakproof to IP67.

High dielectric strength ensures galvanic isolation of control and load circuits conforming to protection class 11. (Isolation group C/250 VAC, VDE-0110). The test voltage between contact and coil is 4 kV a.c. The air and creep distance between contact and coil is more than 8 mm. The smallest distance between the connection pins is 5 mm.

The REL28 relay is equipped with one or two changeover contacts of silver-nickel (AgNi) or silver-cadmium-oxide (AgCdO) for high switching loads of 5 to 16 A a.c./d.c. at 250 V a.c./d.c. which are especially suitable for driving motors and heaters or as an interface between electronics and electro-mechanics. They are available in nominal coil voltages of 6, 12, 24, 48, 60 and 110 V d.c. or 12, 24 and 220 V a.c.

The REL28 relay range is now also UL E146126(M) approved.
