Solid State Relays (SSRs) have become increasingly popular in engineers due to their excellent features and performance. PVAZ172 is a popular SSR among engineers who need reliable, low-cost, and easy to install solutions. So, what is PVAZ172, and what are its application fields and working principles?

PVAZ172 is a type of solid state relay specifically designed to be used in loops where the control signal is Open Collector. This type of relay utilizes a power relay and a silicon-controlled rectifier (SCR) to help the relay switch quickly and reliably with no noise or sparking. The PVAZ172 relay has a maximum power voltage up to 250VAC and a maximum current of 10A. It is also very reliable because it is made with a double-insulated surface, which eliminates any risk of electric shock.

One of the applications of the PVAZ172 relay is in the control of lighting and temperature systems. It is perfect for these types of applications because it has low stand-by power consumption, fast and accurate switching, and reliable performances. It can also be used to control electric ovens, water heaters, electric table fan, industrial heating systems, industrial printing systems, etc. As it is designed to be used in Open Collector loops, it is perfect for applications with low operation voltages.

In order to understand how PVAZ172 works, it is important to first understand the principle of the Open Collector control loop. In an Open Collector loop, the output signal is typically not connected to any other device or power supply. Instead, the output is open or floating, which means that the output can only be connected to another device when the relay is activated. When the relay is not activated, the output is not connected and the current remains at a very low level.

The PVAZ172 uses the Open Collector control loop to switch on and off the power supplied to the circuit. When the input signal is off, the PVAZ172 relay is off, and the power supply remains off. When the input signal is on, the relay activates, and the power is sent to the circuit. By doing this, the PVAZ172 relay is able to quickly and reliably switch on and off the power, which is perfect for temperature and lighting control.

Overall, the PVAZ172 is a reliable and cost-effective solution for applications that need low stand-by power consumption and quick and reliable switching. It is made with a double-insulated surface, which eliminates electric shock risk. Also, its Open Collector control allows the PVAZ172 to be used with low operation voltages, making it perfect for lighting and temperature control.
