Sonit electronics has introduced 2 set point [hi and low] temperature/process controllers for j and k thermocouples, pt-100 rtd sensors and 4-20 ma inputs. It has 3½ digit display, which indicates temperature or parameter values with 0.5% accuracy. The hi and low set points are adjustable by multiturn tc-202 and by thumbwheel potentiometers for model switches for model tc-203. It has control accuracy of ± digit. 1 c/o relay contact of rating 5 a/230 v ac resistive load, for each set point is provided at the output. It incorporates some in-built features such as auto cold junction compensation for t/c inputs, three wire compensation for rtd inputs and open sensor protection. The controllers are enclosed in abs plastic box of size 96 mm [h] x 96 mm [w] x 150 mm [d].
