SRHL1 Series - Single-Phase Solid State Relays (Integrated Heatsink, Left/Right Terminal Type)

SRHL1 Series Single-Phase Solid State Relays (Integrated Heatsink, Left/Right Terminal Type)

The SRHL1 series single phase solid state relays feature integrated heatsinks for excellent heat dissipation efficiency. The left/right terminal layout provides more flexible installation options. The SRHL1 series is available in zero cross turn-on and random turn-on models, and also feature alarm functions for safer operation. The units support both DIN rail mount and panel mount methods.

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.
