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.
