Applications
Timer relays are especially suitable for the use in passenger cars, trucks, buses as well as construction machinery and emergency vehicles. They control pumps, valves or motors, which are meant to overtravel or stay open for a defined period of time. They equally control the co-ordinated, sequential switch-on of loads to avoid load peaks (e.g. with fans).
E-T-A timer relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588.
Technical design
E-T-A timer relays combine a well-proven mechanical contact system with the flexibility of an electronic counter. When replacing a standard automotive relay, you can add ON or OFF delay or both.
