Under-speed control relay TCS series

SPCOAC/DCDIN rail

• input PNP 24Vdc, volt free contact and 15-40Vdc • start surge delay 0,2..20,5s • 4 selectable speed ranges • LED indicators for power supply, relay and status output relay On application of the supply voltagethe output relay energisesand the timing period starts.The TCS monitors the time betweenthe leading edge ofsuccessive input pulses. Whenthe timing period between the pulsesexceeds the set value,the output relay drops out. Auto Reset When the timing period between the pulses returns to the acceptable range for three successive pulses the output relay resets. Manual Reset The output relay resets when terminals +24 and E2 are connected. After breaking the connection time ts starts. supply voltage variation nominal voltage -20%..+10% frequency range 48..63 Hz duty cycle 100%
