The Pepperl + Fuchs KFD2-GR-EX1 is a high-performance trip amplifier designed for seamless integration with Pt100 and Ni100 temperature sensors in industrial settings. This one-channel device is engineered to provide precise monitoring and control of temperature processes within hazardous areas, ensuring operational efficiency and reliability.
Equipped with two relay outputs, the KFD2-GR-EX1 offers the flexibility to set high or low alarms for each switching point, with the mode of operation adjustable to suit specific application requirements. The unit features a 3 1/2-digit LC-display that presents switching points and actual values clearly, facilitating easy monitoring and adjustments.
The input for this device is certified EEx ia IIC, indicating intrinsic safety for use in potentially explosive atmospheres. The KFD2-GR-EX1 also includes lead breakage monitoring, which can be deactivated if necessary, adding an extra layer of operational security.
For ease of use, all operating and indicator elements are conveniently located on the front side of the device. The hysteresis range is adjustable from 1% to 10% of the measuring range, allowing for precise control over the temperature measurement process.
The KFD2-GR-EX1 is designed with safety in mind, featuring safe electrical isolation between the input, output, and power supply in accordance with EN 50020 standards. This ensures that the device operates safely and reliably, even in challenging industrial environments.
Overall, the Pepperl + Fuchs KFD2-GR-EX1 is a robust and versatile solution for temperature monitoring and control in hazardous areas, offering both precision and reliability for a wide range of industrial applications.
