Special Relays

Applications

The special solid state relay portfolio is used in all applications where mechanical relays reach their limits. These devices switch frequently, noiselessly and faster than mechanical relays. They are especially suitable for the use in trucks, buses, agricultural vehicles and forestry equipment, construction machinery, special vehicles and emergency cars as well as watercraft.
The EXR30 special relay is available for DC 23 V applications. EXR10, EXR20 and EXR40 are additionally suitable for DC 24 V applications. All relays of this product group fit into standard automotive relay sockets to ISO 7588.

Technical design

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. These relays stand out due their special additional functionalities.
