New, unused multi-purpose automotive relays of high reliability for 12V operating voltage and current up to 40A. The relays have a built-in protective resistor connected in parallel with the coil (see the factory diagram on the part housing). Two variants available (choose before ordering): 4 pins: price 700 dinars 5 pins: price 700 dinars Operating voltage: 12V DC Maximum switching current: 40A Protection: built-in resistor (resistor protected) to suppress voltage spikes. Advantage of the relay with resistor: When a classic relay is switched off, a back-EMF surge occurs that can damage sensitive drivers in the engine control unit (ECU) or other vehicle electronics. The integrated resistor effectively dampens these current spikes and protects the vehicle's computer. Unlike a diode relay, the resistor relay is not polarized (it makes no difference how you connect plus and minus to pins 85 and 86), which greatly simplifies installation. Intended use: recommended for installation at sensitive points connected to engine electronics (main ECU relay, fuel pump, gas/sequential ECU), as well as for safely connecting high-power consumers such as LED light bars, fog lights, auxiliary fans or sirens.
