    Left/Right Terminal Layout

    The SRHL1 series features a left/right terminal layout offering more flexible installation options. Single phase solid state relays from Autonics is also available in top/bottom terminal layout for application in diverse user environments.


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


    Alarm Function (Overheating)

    The alarm output and indicator (red LED) turns on in case of overheating due to product damage or overcurrent, providing safer operation for users.


    Check Operation Status

    Users can easily check the operation status of the solid state relays through input indicators (green LED)


    Various Installation Methods

    The solid state relay units support both DIN rail mount and panel mount methods providing more installation flexibility



    Single-phase integrated solid state relays are used to control the temperature of heating device in reflow machines.
