The Latest Innovation: KCD2-SCS*

K-System KCD2-SCS*

Positioners are often equipped with analog position indicators that provide feedback to the controller to confirm that the correct position has been reached. This feedback is typically sent back to the control system as a 4 … 20 mA signal. Previously, a separate isolator module was required for the input and output signal. The KCD2-SCS* combines both functions in one device. Find out more about the unique 2-channel devices for analog signals with individual configurability of the channels!

Main Applications

Thermal Power Plants: Direction of Rotation and Speed Monitoring Feedwater Pumps
Task and boundary conditions: Galvanic isolation of control and field side in the safe area and ensuring feed water supply for steam generation

Typical measuring and control tasks: Direction of rotation monitoring and speed monitoring

Typical isolating modules: Frequency converters of the K-System are also available as intrinsically safe devices for applications in hazardous areas.
 
Water Locks: End Position Control
Task and boundary conditions: Galvanic isolation of control and field side in the safe area. Ensuring that the lock gates are closed before water is admitted or discharged into the lock basin.

Typical measuring and control tasks: Feedback of the end position contact to the control system when the lock gates are closed

Typical isolating modules: Switch amplifiers of the K-System are also available as intrinsically safe devices for applications in hazardous areas

Ships: Optical and Acoustic Warning Devices
Task and boundary conditions: Galvanic isolation of control and field side in the safe area, safe switching on of warning devices in case of emergency, and safety integrity level of the signal circuit(s): SIL 3

Typical measuring and control tasks: Transmission of switching signals from the control system to the warning devices

Typical isolating modules: Safety relay with line fault transparency of the K-System.

Pharmaceutics: Control of Valves in Large Plants
Task and boundary conditions: Control of the mass flow of API, hazardous area, safe signal transmission in large plants, different supply modes for a large number of different valves

Typical measuring and control tasks: Control of valves

Typical isolating modules: Intrinsically safe barrier of the K-System KCD2-SLD-Ex2.1545, suitable for bus- and loop-powered supply, high operating margin by output up to 45 mA (for safety-related applications: SIL3 ESD- and DCS systems that need LFT to get SIL level for DO cards/channels)

Sewage Treatment Plants: Speed Monitoring of Archimedean Screws
Task and boundary conditions: Load-dependent control of the Archimedean screws to keep the high energy consumption typical of these plants within limits
 
Typical measuring and control tasks: Speed monitoring
 
Typical isolating modules: Intrinsically safe frequency converters of the K-System. They are also available as isolators for applications in the safe area

Biogas Production: Gas Analysis of Biogas and Landfill Gas
Task and boundary conditions: No constant composition of the biogas; However, gas-fired power plant engines require a constant supply of chemical energy—gases must be continuously analyzed & results incorporated into the control system. Potentially explosive atmospheres.
 
Typical measuring and control tasks: Transfer of gas quality measurements
 
Typical isolating modules: Intrinsically safe K-System transmitter power supply or isolators

Life Sciences: Temperature Monitoring of Process Media
Task and boundary conditions: Temperature monitoring in containers with process media to be heated or mixed so that an upper temperature limit is not exceeded in order to prevent undesirable decomposition or unwanted chemical reactions; potentially explosive atmospheres
 
Typical measuring and control tasks: Temperature monitoring
 
Typical isolating modules: Intrinsically safe K-System temperature converter with output of two configurable limit values or isolators for safe areas
