The solid state relay portfolio is used in all applications where mechanical relays reach their limits. They switch more frequently, quieter and faster than mechanical relays and are particularly suitable for applications in buses and trucks, in agricultural vehicles and construction machinery, in specialty vehicles and passenger cars.

E-T-A solid state relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588.

Solid state relays combine high-end power semi-conductors with comprehensive know-how in the areas of heat management, EMC-compliant design and overcurrent protection. The electronic circuitry ensures wear-free, silent and extremely fast switching operations over the entire life span.

The electronic standard relays type ESR10 Micro are solid state relays for DC 12 V and DC 24 V vehicle applications. This space-saving relay is available in three power classes:

• 10 A for max. 85° C / (12 and 24) Vdc
• 17 A for max. 105° C / (12 and 24) Vdc
• 30 A for max. 85° C / 12 Vdc

Their Benefits Include:

• Silent Switching
• Bidirectional Control
• Low Current Consumption
• Long Life Span

The ESR10 Micro relays can easily replace an electro-mechanical relay because polarity of the control input does not matter. The solid state relays are suitable for switching resistive, inductive and capacitive or lamp loads. Unlike electro-mechanical relays they offer frequency control as an option.
