Our ISO Mini Relays are compact, modular, general-purpose relays that allow you to tailor your vehicle's hard-wired box for the capability you need, including lighting, starting, horn, heating and cooling, or fan control. Adhering to the ISO Mini form factor, these relays plug into existing, standard ISO Mini boxes along with fuses or other components (sold separately). This configuration (RC-200124-DN) is a Form C ISO Mini relay with single-pole, double-throw (SPDT) circuitry. It features a 24 V dc insulated coil with diode suppression and a 20 A continuous current rating. This model also comes with a bracket for panel mounting.
