Green LED for relay in position 1-4, and red LED for relay in position 1-3
1-pole/8A output relay with neutral center position
230 VAC supply voltage
C-mac® time relay RT18 is specially developed for controlling star/triangle contactors. When the supply voltage is connected, the relay is activated between pin 1-4, and the time measuring starts. When the preset time is passed, the relay shifts to neutral position for 100msek., and then it shifts to position 1-3, and stays there, until the supply voltage is disconnected.
