Pepperl+Fuchs KCD2-SCD-Ex1 | 316911 1-Channel SMART Current

Pepperl+Fuchs KCD2-SCD-Ex1 | SMART Current Driver – Part No. 316911

Overview

The Pepperl+Fuchs KCD2-SCD-Ex1 (316911) is a 1-channel isolated SMART current driver, designed to drive I/P converters, control valves, and other actuators in hazardous areas. It accepts a 4–20 mA analog signal from the safe area and transmits it into the hazardous area with HART signal compatibility, while maintaining intrinsic safety and SIL 2 compliance.

This unit ensures reliable and precise signal transmission for demanding process automation tasks, offering galvanic isolation, fault monitoring, and DIN rail mounting in a compact 12.5 mm housing.
