Solid State Remote Power Controller E

Transcription

1 Description The E-T-A is a transistorised switching device providing both protection and signalisation. It is suitable for all applications where the capabilities of the existing PLC s are not sufficient or where no protection against overload and short circuit or wire breakage monitoring of connected loads is provided. The use of a costly, high-capacity card becomes superfluous when only one or two powerful s are necessary. Using the SSRPC in combination with the module plus creates a new, very flexible system capable of being subsequently changed or extended. Busbars, pre-wired signal contacts and spring-loaded terminals reduce installation times considerably (see accessories). Typical applications Automation - interface module providing inexpensive power amplification at PLC s - optimum protection of individual loads by monitoring the load circuit Protection and control of - motors - solenoids - lamps Features Optimum load protection.

2 Technical description Connection diagram At the correct input voltage (> 8.5 V), the SSRPC will switch on a power transistor to connect the load to the plus pole of the load circuit supply ( ). The transistor will switch off when - the control voltage (U E ) is removed - there is a short-circuit/overload in the load circuit. Status indication is provided by two LEDs (red and yellow). Simulated thermal-magnetic overload protection occurs at approx..5 times rated current. See time/current characteristic curves. The SSRPC is fitted with blade terminals D 4644-A and is suitable for plug-in mounting with various E-T-A sockets or module plus (see Accessories). Control circuit ON condition: If a voltage higher than 8.5 V is applied to the input terminals (I N against ), the control current (from the PLC) will flow through the opto coupler. The transistor will be conductive, status indication by yellow LED. OFF condition: A control voltage lower than 5 V will switch the transistor off. fault indication circuit F 4 6 yellow control and monitoring electronics red 5 LE Load circuit The load circuit switches depending on the control signal ( or ). It is electronically monitored for faults. In the event of a short-circuit the circuit is disconnected after max. μs whilst upon inadmissible overload it is disconnected according to the time/current curves shown. Typical time/current characteristics (T A = 5 C).5 A and A Fault indication F The fault indication circuit is physically isolated from the load and control circuits via a. In the OFF condition, this circuit (with closed contact) will provide wire break indication, with the transistor being open. The versions with fault storage () store the fault signal until the control voltage is re-applied. Visual fault indication by red LED. Trip time in ms Dimensions current limitation.
