Spec Sheet

The Model MK-200 is a microprocessor programmable Conductivity controller that accepts a conductivity electrode as an input. Outputs are : (1) on-off or proportional control relay ( this control can be SSR drive or mechanical contacts);(2) a second optional control relay can be added for control above and below the set point or as an alarm ( 3) a 4-20 mA recorder signal proportional to the conductivity level

The power source is from 85 to 265 VAC, 50/ 60Hz free voltage there is no need to change connections for different voltages. The controller is programmable from the front panel via 8 switches, and calibration is done using two adjustment pots.( see programming instructions in the following pages) The front panel is NEMA 4X rated and mounting hardware is provided.
