The PCM-08 time relay is used for controlling the STAR-DELTA contactor switching system. It is utilized in three-phase motor control systems with the winding switching method, allowing for reduced starting currents for larger motor units.

The PCM-08 features:

• Two independent relay outputs activated according to the settings of the potentiometer P1-P3.
• Adjustment of the star start time and the break time between the star and delta systems.

The relay operation is triggered by applying the supply voltage to terminals L, N. It is designed for installation in distribution boards (TH35 rail) and features LEDs that indicate power supply and the device's operational status.
