• LED indicators for power supply, and failure
Control relay to monitor permanent a resistor(TCR01/TCR02) or a diode (TCR01-D/TCR02-D).On the application of the supply voltage and after detection of aresistor or a diode, the output relay “R” energizes.When the control relay detects a short circuit ( UET) the output relay drops out immediately and a redLED lights with short and constant breaks.For following resistor value the control relay is available:RESNOM [Ohm]: 1k2; 8k2; 22k1
