The electronic modules 51001907 and 51001917 are specially designed to convert the position of a potentiometer into a 4-20 mA signal. The 51001907 is used for the standard control units manufactured by Kwant Controls. The module 51001917 is used for a simple conversion of a 360°-position to a single 4-20 mA.

Adjustable R/I-conversion circuit with span- and offset level calibration.  --   10 Volts reference voltage to power the potentiometer.  --  Two internal series resistors of 250W each to connect 358° potentiometers (only for the 51001917).  --   The output signal is isolated from the power supply.   --   Large power supply range (24VDC±30%).    --   ‘Power-on’ indication (green LED).  --   Optionally an external capacitor (e.g. 1000μF/40V) can be connected to smoothen the power supply voltage.  --   The module is mounted on a DIN-rail according to EN50022.   --  CE-approved according to EN60945.

The electronic module 51002997 is designed to convert the position of one double- or two single wiper potentiometers into two 4-20 mA signals.

Two separately adjustable R/I-conversion circuits with span- and offset calibration.   --   One common 10 VDC reference voltage to power the potentiometer(s).   --   Wiring faults of the potentiometer(s) will result in a 0 mA output signal.  --   Wide input range of the potentiometer signal from 10% up to 80%.    -- Two internal series resistors of 1000W each to connect 360° potentiometers.  -- High side output drivers allow signals with a common ground.   --    The output signals are isolated from the power supply.  -- Large power supply range (24VDC±30%).   -- ‘Power-on’ indication (green LED).  -- Optionally an external capacitor (e.g. 1000μF/40V) can be connected to smoothen the power supply voltage.  --  The module is mounted on a DIN-rail according to EN50022.   --  Type approved by ABS, BV, CCS, DNV, GL, LRS, Class NK, RINA, RMRS.
