2 functional description when applying the control voltage (>8,5 v) to the control input of the ssrpc e-1048-s7, the integral power transistor becomes conduc- tive. it connects the plus pole of the load circuit supply (ub) with the load. the transistor will switch off when the control voltage is removed or when there is a short circuit / overload in the load circuit. status indication is provided by two leds (red / yellow). overload disconnection is similar to a trip curve of a thermal- magnetic circuit breaker and occurs at approx. 1.5 times rated current (see time/current characteristic) the device is fitted with blade terminals to en 60934-6.3-0.8 and suitable for plug-in mounting with power distribution module 17plus or the power distribution board svs16 (see separate data sheets). control circuit on condition: if a voltage higher than 8.5 v is applied to the input terminals (+in against gnd), the control current (e.g. from the plc) will flow into the electronic circuitry. the output transistor will be conductive, status indication by yellow led. off condition: a control voltage lower than 5 v will switch the output transistor off. load circuit the load circuit switches depending on the control signal (0 or 1). it is electronically monitored for faults. in the event of a short circuit the circuit is disconnected after max. 250 ms whilst upon inadmissible overload it is disconnected according to the time/current curves shown. fault indication output f the fault indication circuit is physically isolated from the load and control circuits via a relay. depending on the version this circuit (with closed contact) will additionally provide wire break indication. in the on condition, short circuit or overload will be monitored and indicated. the led indicates a failure. all dimensions without tolerances are for reference only. e-t-a reserves the right change specifications at any time in the interest of improved design, performance and cost effective - ness, the right to make changes in these specifications without notice is reserved. product markings may not be exactly as the ordering codes. errors and omissions excepted. connection diagrams e-1048-s7xx schematic diagram time/current characteristic (t amb = 25 c) 11 1 e-1048-s7... 1 14 1 trip time in ms 1000 1 2 100 10 1 0,1 0 current limitation (typ. 150 ma) ...times rated current i n i (a ) 12.3 blade terminals en 60934-6.3-0.8 60 70 10.3 50 6x6.8=40.8 6.8 reverse plug-in protection xxa in led yellow led red f e-104 8 -s70x e-1048-s7xx-dc24v -xxa made in germany xxxx solid state remote power contr oller germany 2 12 14 13 11 1 line+ gnd sc so in+ load+ signal control in dimensions solid state remote power controller e-1048-s7... www.e-t-a.de solid state remote power controller e-1048-s7... 1646 5
