Siemens Solid State Relay, Zero-Cross Switching Type, 20A Current Rating - SIRIUS Classic Series - 3RF2320-1AA02 Power up your circuit in a flash using this solid-state relay from Siemens. It changes an electrical signal to an optical one before sending it to the circuit, meaning it works without any moving contacts. This means there's minimal risk of wear and you get long-lasting performance. The unit uses zero-cross switching, so it turns on when the load voltage is close to zero to minimise noise. Mount it in a snap by simply clipping it to your DIN rail. You can use this device to control your robotics and instrumentation systems. • IP20 rating means it's finger-safe and protected against objects larger than 12mm
• Broad operating temperature range between -25°C and +60°C for use in challenging environments
• Compact dimensions of 100 (H) x 22.5 (W) x 140.5mm (D) to add minimal bulk to your rail
• Screw terminals for a secure, vibration-proof connection without the need for special tools What's the current rating of this SSR? This relay has a current rating of 20A, so it's a safe bet for use with heavy-duty equipment.
