The Coil Driver / Relay Combo is a combination of the Single Coil Driver & Electronic Relay in the same enclosure. This will reduce cost for distributor applications. The relay can handle 45 Amp and is epoxy sealed. The driver is over-current and over temperature protected in short circuit circumstances. The Coil driver is over-current and over temperature protected in short circuit circumstances. It has a primary cut-off voltage of 360V which will generate around 36kV breakthrough voltage. It can be used with other ECU systems.
