SMART Current Driver KFD2-SCD2-Ex1.LK for Hazardous Area Signal Control

The SMART current driver KFD2-SCD2-Ex1.LK from Pepperl+Fuchs is a 1-channel isolated barrier for analog output signals. It helps automation teams drive 4 to 20 mA field devices in hazardous area applications. Therefore, it is a practical choice for process plants, chemical units, oil and gas systems, and instrument maintenance projects.

KFD2-SCD2-Ex1.LK supports a 24 V DC supply through Power Rail or terminals. It provides a current output with load capability up to 650 ohms. In addition, the unit supports line fault detection, so technicians can identify open-circuit or short-circuit wiring issues faster. This helps reduce troubleshooting time during shutdown repair and control loop commissioning.

Pepperl+Fuchs Barrier Features

This SMART current driver is designed for analog output signal isolation between the control side and field side. It supports HART communication for smart field instruments and valve positioner applications. Moreover, its 0.1% accuracy helps maintain stable control signal performance in demanding process environments.
