The Smart power relay E-1048-8D from ETA, is a remotely controllable electronic load disconnecting relay with two functions in a single unit:
- Electronic Relay
- 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 1A through 25A. An operating voltage range of DC 9...32V allows the connection of DC 12V and DC 24V loads.
In order to switch and protect loads remotely, it has until now been necessary to connect several discreet components together:
- an electro-magnetic relay, control cable and integral contact to close the load circuit
- an additional protective element (circuit breaker or fuse) for cable or equipment protection.
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.
The E-1048-8D is suited to all applications with DC 12 or 24V circuits, where magnetic valves, motors or lamp loads have to be switched, protected or monitored:
- road vehicles (utility vehicles, buses, special vehicles)
- rail vehicles
- marine industry (ships, boats, yachts etc)
The power relay from ETA is also suitable for industrial use (process control, machine building, engineering) as an electronic coupling relay between PLC and 12 or 24 volt loads.
Options: ratings from 1 to 25Amp, increased environmental protection and either short circuit protection or short circuit and overload protection.
