The SDV-FH71T AC240V is a monitor-current-voltage relay output device suitable for many different applications. This device is perfect for applications that require the monitoring of an AC or AC/DC voltage, current, or other power ratings. Additionally, this device is also equipped with a built-in positive temperature coefficient (PTC) circuit breaker that will protect against overcurrent and overvoltage conditions.

The SDV-FH71T AC240V application field includes general monitoring, signalling, voltage and current control, and overload protection applications. It is also widely used in power distribution, electrical automation, protection, and environmental monitoring systems. As a monitor-current-voltage relay output device, the SDV-FH71T AC240V provides accurate monitoring, reliable protection, and easy integration into any system.

In terms of working principle, the SDV-FH71T AC240V monitors and compares the levels of current or voltage in an AC, AC/DC, or DC power circuit. An adjustable threshold limit can be set on this device, and once the limit is reached, the internal relay in the device will be activated. Depending on the application, the relay output can be used to send an alarm signal, trip the circuit, or open/close a normally open or normally closed contact.

The SDV-FH71T AC240V also features a positive temperature coefficient (PTC) circuit breaker, which provides reliable protection against both overcurrent and overvoltage conditions. The PTC circuit breaker will open the circuit even when the monitoring value is close to the settrip limit, ensuring safety and reliability. Additionally, the device has a wide operating temperature range and is UL508-approved, making it an ideal choice for almost any industrial application.

In conclusion, the SDV-FH71T AC240V is a reliable and feature-rich device that is perfect for powering control, monitoring, and protection systems. It is designed to be easy to install and integrate into any existing system, and the built-in PTC circuit breaker makes it well suited for a wide variety of applications. It is also UL508-approved, making it an excellent choice for industrial applications where safety is of the utmost importance.
