Two Mounting Hole Types

Two different mounting holes types and sizes allow flexible installation and mounting on various types of heatsinks.

The SR2/3 series which is a popular Solid State Relays series from Autonics company, is also available in various other user settings.

Built-In Alarm (Overheating) Function

In case of overheating due to product damage or overcurrent, the alarm output turns on and the red LED indicator provides safer operation for users.

Low Voltage Models Available/Dielectric Strength Up to 4000VAC

24VAC low voltage models are available for flexible application in diverse settings. Select models feature high dielectric strength of up to 4000VAC.

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.

Status Indicators

The input indicator (green LED) allows users to quickly identify the operation status of the relays.
