Solid State Remote Power Controller E-1071-0736Solid State Remote Power Controller E-1071-073In principle, the E-T-A SSRPC E-1071-073 operates like conventionalelectro-mechanical relays, with additional protective and signalfunctions. The control input replaces the magnetic coil and the powertransistor replaces the main contact.Control circuitThe control current flows through the LED and the opto couplerimmediately a voltage higher than 8.5 V (= control signal “1”) isapplied at the input terminals (6 and 7). The opto coupler transmits thesignal to the load circuit, at the same time switching the loadtransistor on. This signal is transmitted as a status signal to allmonitoring circuits. The input protection diode protects the controlvoltage from incorrect polarization. Control current limitation isprovided by a constant current diode.Load circuitThe load circuit is switched ON or OFF according to the control signal(“0” or “1”), with electronic circuits monitoring the load circuit for faultssuch as overload or short-circuit. Should one of these faults occur, themonitoring circuitry will immediately react, causing the load transistorto disconnect and the circuit breaker to trip. Transistor disconnectionoccurs according to the storage time characteristics. The storage timeincreases noise immunity avoiding disconnection of non-harmfulpeaks such as those caused by inrush currents from lamp loadconnection. Storage time is not a constant quantity but is inverselyproportional to the overcurrent factor.Status indicationStatus indication is provided by 2 LEDs (yellow and green) on the frontof the housing.YELLOW LED = correct control voltageThe LED indicates when the control voltage ishigher than 8.5 V, with control current flowing.GREEN LED = correct load currentThe green LED indicates when the load current ishigher than 0.2 A.Faults such as too high a load resistance, wire break, poor contact, oroverload/short-circuit, are available when only the yellow LEDindicates. SSRPC E-1071-073 includes two current measuringterminals (2 mm dia.) on the front. These terminals provide for loadcurrent measurement in terms of voltage drop at the 0.1 Ω shunt in theload circuit.Storage time characteristic curve t s (T A = 25 °C)time in ms100010020105I N 2Operating modes3current limitation4 5 x I N(theoretical overcurrent factor)Operating status Fault-free Short-circuit Wire breakoperation on the loadControl input U Contr “0” “1” “1” “0” “1”YELLOW LED - 0 1 1 0 1control currentGREEN LED - 0 1 0 0 0load current monitoringAuxiliary contact open open closed open openRemarks load load circuit breakerOFF ON tripped1 - LED indicates0 - LED does not indicate6- 34www.e-t-a.comIssue B
