Pepperl+Fuchs KFD2-STC4-Ex1-Y122583 Transmitter Power Supplies Isolated Barriers

Description

The KFD2-STC4-Ex1-Y122583 is a sophisticated SMART Transmitter Power Supply designed for intrinsic safety applications in hazardous environments. It provides reliable power to 2-wire and 3-wire SMART transmitters in hazardous areas while transferring analog signals to safe areas. This device is particularly useful in applications requiring precise signal transmission and conversion, such as in Industrial Automation and process control systems. With its advanced features and robust design, the KFD2-STC4-Ex1-Y122583 ensures safe and efficient operation in demanding industrial settings.

Features

The KFD2-STC4-Ex1-Y122583 features a single-channel isolated barrier with a 24V DC supply, powered via a Power Rail. It supports input from 2-wire and 3-wire SMART transmitters and current sources, converting the input signal into an isolated current output in sink mode. The device includes integrated test sockets for HART communicators, facilitating easy maintenance and configuration. It is designed with reinforced insulation according to IEC/EN 60079-11, ensuring a rated insulation voltage of 375 Veff. The KFD2-STC4-Ex1-Y122583 also supports a wide ambient temperature range of -20°C to 60°C (-4°F to 140°F) and includes a unique collective error messaging feature when used with the Power Rail system. It is certified for use in hazardous areas, meeting ATEX and IECEx standards for intrinsic safety.

Function

The primary function of the KFD2-STC4-Ex1-Y122583 is to supply power to SMART transmitters in hazardous areas and transfer the analog input signal to the safe area as an isolated current value in sink mode. It achieves this by converting the input signal and providing a stable output signal, which can be configured to meet specific application requirements. The device also supports bi-directional transfer of digital signals superimposed on the input signal, enabling effective communication between hazardous and safe areas. Its ability to operate within a wide temperature range and its robust design make it suitable for various industrial applications, ensuring reliable performance in harsh environments. The device is designed to provide a sink mode output on the safe area terminals and includes a 250Ω internal resistor between terminals 8 and 9 for use when the HART communication resistance in the loop is too low.
