Smart Power Relay E-1048-8D... Description The Smart Power Relay E-1048-8D is a remotely controllable electronic load disconnecting relay with two functions in a single unit: l electronic relay l electronic overcurrent protection The 4 pin DICE version is designed for use with standard automotive relay sockets. A choice of current ratings is available from 1 A through 30 A. An operating voltage range of DC 9...32 V allows the connection of DC 12 V and DC 24 V loads. In order to switch and protect loads remotely, it has until now been necessary to connect several discreet components together: - an electro-mechanic relay, control cable and integral contact to close the load circuit - an additional protective element (circuit breaker or fuse) for E-1048-8D DICE version cable or equipment protection Now type E-1048-8D combines these two functions in a single Technical Data (T = 25 °C at U ) unit, thus minimising the number of connections in the circuit A N and thereby reducing the risk of failures.
