The Pepperl + Fuchs KFD0-RO-EX2 Relay Module is a high-performance interface solution designed for intrinsic safety applications within industrial settings. This 2-channel isolated barrier is engineered to switch intrinsically safe circuits on the field side, making it an ideal choice for applications such as remote resets, fire alarm tests, or remote calibration of strain gauges.

Constructed with reliability in mind, the KFD0-RO-EX2 features galvanic isolation between its outputs and inputs, ensuring that signal integrity is maintained without interference. The inputs are non-polarised and share a common reference potential, simplifying installation and maintenance. Each input is safeguarded by a fuse and electronic current limiting, providing an additional layer of protection against electrical anomalies.

The module is loop-powered with a rated voltage of 15 to 30 V DC and has a minimal power dissipation, making it energy efficient. It is capable of handling input currents of up to 21 mA per channel and offers contact loading of 230 V AC/2 A with a cos φ > 0.7 or 40 V DC/2 A for resistive loads. The mechanical life of the relay module is impressive, with up to 5 million switching cycles, and it operates within an ambient temperature range of -20 to 65 °C, accommodating a variety of environmental conditions.

For ease of monitoring, the KFD0-RO-EX2 is equipped with LED indicators and provides space for labelling at the front, ensuring clear and straightforward identification. The module's compact dimensions and IP20 protection rating make it suitable for mounting on a 35 mm DIN rail, conforming to EN 60715 standards.

The KFD0-RO-EX2 is compliant with international safety and electromagnetic compatibility standards, including ATEX and IECEx certifications, which attest to its suitability for use in hazardous areas. This relay module is a robust and dependable choice for engineers and technicians looking to enhance the safety and efficiency of their control systems.
