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
electronic overcurrent protection
lꢀ
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
cable or equipment protection
E-1048-8D DICE version
Now type E-1048-8D combines these two functions in a single
unit, thus minimising the number of connections in the circuit
and thereby reducing the risk of failures.

Type E-1048-8D is suited to all applications with DC 12 V or DC 24 V
circuits, where magnetic valves, motors or lamp loads have to be
switched and protected:
- road vehicles (utility vehicles, buses, special vehicles)
- construction and agricultural machinery
- rail vehicles
- marine industry (ships, boats, yachts etc.)
The Power Relay is also suitable for industrial use (process control,
machine-building, engineering) as an electronic coupling relay between
PLC and DC 12 V or DC 24 V load

Compared to electro-mechanical relays, only a fraction of the

closed-circuit current or switching current is needed. This is
important for battery buffered load circuits which have to remain
controlled even with the generator off line.
The extremely low induced current consumption of less than 50 µA is
absolutely necessary for battery buffered applications.
The load circuit is disconnected in the event of a short circuit
(ENTRY version) or overload/short circuit (ENTRYprotect version).
