Pepperl+Fuchs KFA5-SR2-Ex2.W Switch Amplifiers Isolated Barriers

Description

The KFA5-SR2-Ex2.W is a reliable 2-channel isolated barrier designed for intrinsic safety applications in industrial settings. It efficiently transfers digital signals from NAMUR sensors or mechanical contacts in hazardous areas to safe areas. This model is powered by a 115 V AC supply and is equipped with form C changeover relay contacts for the safe area load. The device is constructed with a polycarbonate housing, ensuring durability and resistance to environmental stresses. Its protection degree of IP20 makes it suitable for indoor use in controlled environments. The KFA5-SR2-Ex2.W is designed to be mounted on a 35 mm DIN rail, adhering to EN 60715 standards, which simplifies installation and integration into existing infrastructure.

Features

The KFA5-SR2-Ex2.W features a removable terminal block with an integrated self-opening device, simplifying installation and wiring while ensuring secure connections. The device operates within a temperature range of -20°C to 60°C, making it suitable for a wide range of environmental conditions. With a rated voltage of 103.5 to 126 V AC and a power consumption of ≤ 1.3 W, the KFA5-SR2-Ex2.W ensures energy efficiency without compromising performance. Its compact design allows for efficient use of space, making it an ideal solution for applications where panel space is limited. The device also supports line fault detection, which can be enabled or disabled via switch S3, enhancing operational safety and reliability. Additionally, it includes a unique collective error messaging feature when used with the Power Rail system, providing immediate notification of errors and enhancing system reliability. The switching point of the device is designed to operate within a range of 1.2 to 2.1 mA, with a switching hysteresis of approximately 0.2 mA, ensuring precise and reliable signal transmission.

Function

The KFA5-SR2-Ex2.W functions to transfer digital signals from hazardous areas to safe areas while maintaining galvanic isolation between the two. This ensures that any noise, potential differences, or transients from the hazardous area do not affect the safe area control circuits. The device uses a zener barrier in combination with a galvanic isolation network to limit the energy transmitted to the field, thereby ensuring intrinsic safety. In the event of a fault in the field circuit, the relays revert to their de-energized state, and the LEDs on the device indicate the fault according to NAMUR NE44 standards. This feature ensures quick identification and resolution of issues, minimizing downtime. The device also supports a pulse/pause ratio of ≥ 20 ms/≥ 20 ms, making it suitable for applications requiring precise timing and control. The KFA5-SR2-Ex2.W is certified for use in hazardous locations, adhering to international safety standards and protocols, making it suitable for applications in oil and gas refineries, chemical plants, and other hazardous environments where safety and reliability are paramount.
