E-1048-8I4-C3D4V1-4U3-1A产品概述
The Smart Power relay E-1048-8I is a remotely controllable electronic load disconnecting relay with three functions in a single unit: Electronic relay Electronic overcurrent protection Status indicationThe 7 pin INLINE version is designed for use with various E-T-A terminal blocks. A choice of current ratings is available from 1A through 20A. An operating voltage range of DC9-32V 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-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-1048-8C combines all of these functions in a single unit, thus minimizing the number of connections in the circuit and thereby reducing the risk of failures.Applications:Type E-1048-8D is suited to all applications with DC 12V or DC 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 is also suitable for industrial use (process control, machine-building, engineering) as an electronic coupling relay between PLC and DC 12V or DC 24V load.Features: 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. Extremely low induced current consumption of less than 1 mA Load circuit is disconnected in event of an overload or short circuit. Load circuit is permanently monitored for wire breakage. Two status outputs for control signal AS and group signal SF provide status indication. Colored label; eg red=10A, see ordering information on data sheet for more details.
