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 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. Technical Data (TA= 25 °C at UN) Power supply LINE + Applications 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 Features l l l l l l Integral power electronics provide a wear-resistant switching function, insensitive to shock, vibration and dust. 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). For switching and monitoring loads of 30 A plus it is possible to connect several units in parallel. Uniform power distribution between units must be ensured by symmetrical design of the supply cables (length and cross section).

To ensure equal distribution of current between units, symmetrical design of the supply feed is necessary (length and cross section). 1) 1646 50 µA Load circuit LOAD Trip time (standard curve) 1) Approvals DC power supply with small R i battery and generator etc. DC 12 V/DC 24 V DC 9...32 V typically www.e-t-a.de 1 Smart Power Relay E-1048-8D...
