K31D

Differential controller, 2 inputs, 4 outputs and RS485

It’s a digital controller equipped with 2 inputs for PTC, NTC or Pt1000 type temperature probes through which it is possible to achieve differential temperature control and can therefore be used in applications requiring control based on the temperature difference between two different environments such as fluid coolers (chillers), natural air conditioning systems for environments through air recirculation, heating through thermal solar panels or in many other applications where two temperature measurements are required.
