G3NA-290B-UTU-2 DC5-24

Solid State Relays

G3NA-290B-UTU-2 DC5-24 is a type of solid state relay (SSR) that consists of two parts: an input interface and an output relay. Solid state relays are most commonly used to control the power supply of electrical equipment, such as motors, pumps, and heaters. This SSR model is designed to be used in applications with lower loads and voltage, and it has a wide range of applications such as controlling temperature control systems, switching on/off motors, and controlling light dimmers.

Solid state relays are a form of electric switch that use a semiconductor device, such as a thyristor, triac, diode, or transistor, to control an electrical circuit. Unlike traditional mechanical relays, SSRs have no actual moving parts, which makes them more durable and reliable. They are also able to control a load more precisely and offer faster switching speeds.

The G3NA-290B-UTU-2 DC5-24 is designed with a wide variety of features to make it an ideal choice for many different applications. The input interface consists of two dry contacts that can be used to control the load and a 5 Amp rated power supply for the SSR. The output relay is a 24 VDC, 4 Amp, 250VAC, zero-crossing type, which offers a wide range of load control. The input and output terminals are protected against voltage surge up to 1500 V for a maximum of 2 seconds. The SSR also has phototransistor protection, which prevents it from turning on when a surge spike is detected.

The working principle of the G3NA-290B-UTU-2 DC5-24 is based on zero-crossing principle. When the voltage applied to the input contacts reaches zero, the SSR will switch on and allow current to flow through the load. When the voltage drops again, the SSR will switch off. This provides precise control over the load and eliminates any arcing inside the relay. Additionally, the SSR is capable of switching very quickly, making it ideal for applications that require a very short response time.

The G3NA-290B-UTU-2 DC5-24 solid state relay is an ideal choice for many applications where precise control and fast response time is needed. Its input and output terminals are protected against control surges, which makes it reliable in harsh environments. Additionally, it offers a wide range of load control, which makes it suitable for many different applications.
