Product Description
The KFD2-STC4-1 is a high-precision single-channel signal conditioner designed to provide reliable power and interface capability for SMART transmitters in industrial control loops. It functions as both an isolation interface and power supply module for 2-wire and 3-wire SMART transmitters, as well as 2-wire SMART current sources, ensuring stable and accurate signal transmission within the loop.
Designed with functional safety in mind, the KFD2-STC4-1 is certified up to SIL2 in accordance with IEC 61508, making it suitable for safety-critical process control applications. The module includes integrated test points on the terminals, allowing maintenance technicians to perform loop diagnostics without interrupting the signal path. Its slim-line modular housing enables high-density installation in standard industrial control cabinets.

Technical FAQ
Does the KFD2-STC4-1 require a separate power supply for each module?
No. The KFD2-STC4-1 is designed to be powered through a Power Rail system, which distributes the 24 V DC supply across multiple modules and simplifies wiring in multi-module installations.
Are the integrated test points safe for live measurements?
Yes. The built-in test points allow technicians to measure the loop current safely without disconnecting the circuit, enabling diagnostics and calibration while maintaining continuous process operation.
