Smart Power Relay E-1048-8I... Description The Smart Power Relay E-1048-8I.- is a remotely controllable electronic load disconnecting relay with three functions in a single unit: l electronic relay l electronic overcurrent protection l status indication The 7 pin INLINE version is designed for use with various E-T-A terminal blocks, e. g. 17-P10-Si. A choice of current ratings is available from 1 A through 20 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 - a device for current measurement (shunt) Now type E-1048-8I. combines all these functions in a single unit, thus minimising the number of connections in the circuit and thereby reducing the risk of failures. Applications Type E-1048-8I. 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, protected or monitored: - road vehicles (utility vehicles, buses, special vehicles) - 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 l l Integral power electronics provide a wear-resistant switching function, insensitive to shock and vibration. Only a fraction of the control power needed by electro-mechanical relays is required for switching loads. 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 1 mA is absolutely necessary for battery buffered applications. The load circuit is disconnected in the event of an overload or short circuit, the trip curve is also suitable for smaller motor loads. The load circuit is permanently monitored for wire breakage. Two status outputs for control signal AS and group signal SF provide status indication. For processing the actual value of the current flow in a power management system an analogue output from 0 to 5 V is provided. This voltage signal may also be used as an input to a control circuit or to switch off the unit by means of external control in the event of low load current value. For switching and monitoring loads of 20 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).
