Types of loads resistive, inductive, capacitive, lamp loads, motors (depending on duration of inrush current) ENTRY version Load output with short circuit protection ENTRYprotect version Load output with short circuit and overload protection (typically 200 ms at ILoad typically 1.3 x IN) IN = 1 A...10 A: see trip curve 1 IN = 15 A...30 A: see trip curve 2 Typical voltage drop UON at rated current IN 1) only ENTRYprotect Switching point 1) typically 1.3 x IN (-40 °C...+85 °C: 1.1...1.5 x IN) Trip time (standard curve) 1) typically 200 ms with switch-on onto overload and/or load increase on duty Max. overload IN = 1 A...10 A: 60 A (at L/R = 3 ms) IN = 15 A...30 A: 200 A (at L/R = 3 ms) Parallel connection of channelsfor loads of 30 A plus, several units of identical current ratings may be connected in parallel. To ensure equal distribution of current between units, symmetrical design of the supply feed is necessary (length and cross section). 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 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. 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 l Integral power electronics provide a wear-resistant switching function, insensitive to shock, vibration and dust. l 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. l The extremely low induced current consumption of less than 50 µA is absolutely necessary for battery buffered applications. l The load circuit is disconnected in the event of a short circuit (ENTRY version) or overload/short circuit (ENTRYprotect version). l 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). l Coloured label, for the identification the rated current (e. g. red = 10 A).
