KFD2-SH-EX1

What is the purpose of the isolated barrier?

The isolated barrier is designed for galvanic isolation of signals such as 20 mA and 10 V standard signals, or for adapting or standardizing signals. It also transfers digital signals from hazardous areas to safe areas, ensuring safe operation in control and instrumentation technology.

Can this device be used in hazardous areas?

Yes, the device has intrinsically safe circuits that are used for operating intrinsically safe field devices in hazardous areas. It is suitable for use in Zone 2 hazardous areas and can be installed in non-hazardous areas as well.

What are the mounting requirements for this device?

The device should be mounted on a 35 mm DIN mounting rail according to EN 60715. It must be installed in a controlled environment that ensures a pollution degree of 2 or better and in an environment of overvoltage category II or better.

What type of maintenance is required for this device?

The device should not be repaired, modified, or manipulated. If there is a defect, it should be replaced with an original device. Regular proof tests should be conducted to ensure functional safety, especially when operating in low demand mode.

How should the device be disposed of at the end of its service life?

The device, along with any built-in components and batteries contained within, must be disposed of in compliance with the applicable laws and guidelines of the respective country.

What should be done if the device is damaged or polluted?

Do not use a damaged or polluted device. If you identify any damage or pollution, replace the device with an original unit to ensure continued safe operation.

What are the electrical specifications for the switch amplifier?

The switch amplifier operates with a supply voltage of 24 V DC, a current consumption of 16.8 mA, and has an output voltage capacity of up to 40 V AC/DC. It is designed to handle resistive loads and has a specific electrical life depending on the load conditions.

What safety certifications does this device hold?

The device holds ATEX and IECEx certifications, making it compliant with international standards for equipment intended for use in potentially explosive atmospheres.

Is a configuration necessary before using the device?

No, a configuration of the device is not necessary and not possible. It is designed for easy installation and use without the need for complex setup procedures.

What is the useful life time of the device?

The useful life time of the device is dependent on the component itself and its operating conditions, particularly temperature. However, it is generally assumed to be within a range of about 8 to 12 years, with the possibility of extension if ambient conditions are favourable.
