Datasheets

K-System signal conditioners offer the same architecture as the isolated barriers in versions for non-intrinsically safe circuits. They galvanically isolate field instruments from the control system and convert signals into the format required by the DCS or PLC.

The range includes transmitter power supplies and HART-compatible SMART current drivers, repeaters, current/voltage converters, RTD and universal temperature converters, solenoid drivers and signal converters with a relay trip value and a display showing the measured value.

Key features

Galvanic isolation between field and control system for non-intrinsically safe applications
Transmitter power supplies and SMART current drivers with HART transfer
Loop-powered versions with low voltage drop (5 V)
Trip value converter: 0–20 mA, 0–10 V or 0–60 mV inputs, current or voltage outputs and relay
Pt100 and universal temperature converters with sensor breakage detection
Line fault detection (LFD) and versions up to SIL 3
Power Rail, universal AC/DC or loop supply; 12.5 mm or 20 mm width
