Pepperl+Fuchs 12.5mm wide KC Series Signal Conditioners are now available with spring terminals to simplify and speed installation. In addition to their slim footprint, KC modules consume minimal power to reduce heat output when compared with competitive signal conditioners. Their size and energy efficiency makes them an ideal signal conditioning solution in control rooms with limited space in both hazardous area, as well as general-purpose locations. KC modules are also available with screw terminals.
The SIL rated KC modules deliver broad range with 3-port isolation, and are easily programmed and configured in the field with pushbutton or dip switch logic functions. They provide limit detection with form C alarm contacts, as well as fault detection and alarm functionality. Additional features include:
- Loop-powered and analog isolators
- Removable terminals reduce maintenance
- Lower cost of ownership compared to the competition
- In a large project, KC modules smaller size can potentially reduce the number of cabinets required, eliminating the costs of additional cabinet hardware and wiring
- Because KC modules consumes less power, users may be able to use smaller power supplies than would otherwise be required
- Consuming less power reduces heat generation, and less heat means smaller cooling systems, further reducing cabinet space requirements
The key to process control is accuracy, both in terms of measurement and signal conditioning. The biggest threat to effective process control is the presence of ground loops. Whenever analog data is transferred through long cable runs, there is a high probability that ground loop problems will occur. A ground loop exists when multiple earth ground connections are made in a system. A difference in potential between the grounds generates an extraneous current flow in the signal conductor. The result is commonly known as noise.
In its mildest form, noise in the signal line causes measurement offsets, incorrect sensor readings and general signal corruption. In its most severe form, noise contamination erodes communication to a point where process control is lost. Signal conditioners provide the necessary isolation as well as amplification, filtering and linearity corrections to prevent noise.
