Review on ESUPPORT 12V 40A Car Automotive Van Boat Truck 4 Pins ๐ SPST Alarm Relay Air Heavy Pack of 5: Optimize Power Control and Security by Matt Minette
Photo does not match product
The product photo shows a specific brand and pinout, but the product received does not match. There was no trademark. More importantly, the product photo shows the relay including a resistor in parallel with the relay coil. The purpose of the resistor is to dampen voltage spikes that occur when the coil is de-energized. The relays that came with it had no resistance (I opened one of the relays and checked for a resistance). The relay worked in my application, but I'm sure it generates more spikes than a relay containing a resistor.
