Solid State Relays have been used extensively in a wide variety of industrial applications due to their ability to deliver reliable, consistent performance over a wide range of temperature and environmental conditions. The C347STR is a solid-state relay (SSR) designed for industrial applications. It consists of an input side, output side, control circuit, and packaging components.

Application Field

C347STR solid state relay can be used in a variety of applications including temperature control, long-time delay control, single-phase induction motor control, and more. It has a wide operating range of -40 to +60 degrees Celsius, which allows it to be used in a range of applications. C347STR relays are also compatible with a variety of input signals, including voltage, current, or resistance. Additionally, C347STR relays are suitable for use in automotive, home appliances, heating, ventilation, air conditioning, and other applications.

Working Principle

The C347STR solid state relay is designed to operate on DC current input. It takes the DC input from other devices and converts it into an AC signal that is suitable for controlling an output such as turning on and off lights, motor starters, heaters, or other AC devices. The C347STR is constructed from a transistor, an SCR, and a couple of resistors, capacitors, and an opto-triac. The SCR is used to control the voltage level of the AC output signal. The transistor is used to amplify the signal from the opto-triac. When the DC current is applied to the input side, it passes through the opto-triac, which is then activated, enabling current to flow from one side of the output to another.

C347STR solid state relays provide a high degree of reliability, flexibility, and cost efficiency, making it ideal for a variety of industrial applications.
