The software of the MFR20 multifunctional relay allows many customer-specific adjustments when replacing a standard automotive relay, e.g. monitoring of frequency and voltage, pulse outputs or switching loads on or off.
The MFR20 multifunctional relay features a mechanical contact system for high continuous current.
- Fast and direct exchange of standard automotive relays by intelligent relays with additional functions.
- Reduction of complexity through a customer-specific software that can specially be adjusted to customer applications.
The MFR20 multifunctional relays are available for DC 12 V and DC 24 V applications and are suitable for standard automotive relay sockets to ISO 7588 (ISO MAXI).
Software and specification of requirements are set up in direct co-operation with our customers.
