2,500VAC Dielectric Strength

The dielectric strength of 2,500VAC provides durable and stable performance.

Dielectric Strength : 2,500VAC

Various Types Available

Various models are available depending on load voltage or socket types, offering users wider options for various applications.

 

SRS1-A: AC, DC, AC/DC Control (Autonics SK-G05 sockets)
SRS1-B: AC Control (Universal LY2 sockets)
SRS1-C: AC, DC, AC/DC Control (Universal MY4 sockets)

 

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

Zero Cross Turn-On
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
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 control of power.

 

Check Operation Status

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