Zero Cross Turn-On/Random Turn-On Models Available

Zero Cross Turn-On

The relay switches ON/OFF when the voltage reaches the zero-crossing point of the sine wave. This method minimizes surge current and inrush current, and is ideal for most common industrial loads.

Random Turn-On

The relay opens or turns on immediately when the input signal is applied and turns off when the signal is removed. This method allows phase-control applications requiring precise power control.

Check Operation Status

Easily check the operation status of the unit with the input indicator (red LED).
