KFD2-CR-EX1.30-300 Signal Transmitter — Product Description

The KFD2-CR-EX1.30-300 Signal Transmitter is a highly reliable intrinsic-safety isolating interface module designed for safe signal transmission between hazardous areas and safe control systems. Engineered for modern process automation environments, this module converts low-level analog signals from intrinsically safe field devices into stable, interference-free output signals suitable for PLC, DCS, and monitoring systems. It is widely used in chemical plants, oil & gas installations, refineries, pharmaceutical manufacturing, and other industries where explosive atmospheres may be present.

This DIN-rail mounted signal transmitter provides galvanic isolation between input, output, and power supply circuits, ensuring maximum protection of control equipment and measurement accuracy. It accepts standard current signals (such as 4–20 mA) from field transmitters located in Zone 0/1 hazardous areas and safely transfers them to the safe area without compromising signal integrity. The device minimizes noise, ground loop effects, and electrical disturbances, which helps maintain stable process readings and improves overall system reliability.

The KFD2-CR-EX1.30-300 also features a compact 22.5 mm housing, allowing high-density cabinet installation and easy integration into existing control panels. LED status indicators provide clear operating diagnostics, enabling maintenance teams to quickly verify operating conditions. The module is compatible with a wide range of sensors and transmitters including pressure, temperature, and flow transmitters.

With international hazardous-area approvals and robust EMC immunity, this signal transmitter ensures continuous operation in demanding industrial environments. The maintenance-free design and long operational life reduce downtime and operating costs, making it an excellent solution for engineers and plant operators seeking dependable intrinsic-safety signal isolation and accurate analog signal transmission.
