2,500VAC Dielectric Strength

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

The SRS1 series which is a popular Solid State Relays series from Autonics company, is also available in various other user settings.

Various Types Available

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

1. SRS1-A

AC, DC, AC/DC Control (Autonics SK-G05 sockets)

2. SRS1-B

AC Control (Universal LY2 sockets)

3. SRS1-C

AC, DC, AC/DC Control (Universal MY4 sockets)

Zero Cross Turn-On/Random Turn-On Models Available (Voltage Input Type)

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.

Check Operation Status

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