> Introduction ::

Pantech's Difference/Averaging Indicator cum Controller, model 806 is an ideal instrument for providing indication as well as controlling set points on difference/average of two processes. It is designed to accept various process inputs (Current, Voltage, RTD, and Thermocouple), display the same and generate potential free contacts on either individual process or difference/average of two processes when abnormal conditions occur. The model is equipped with an optional analog output facility (Isolated or non-isolated).

Model 806 is an analog electronics based controller. It is capable to display the process value to the resolution of maximum 3 ½ digits and can be designed to generate maximum of 4 nos. of potential free contacts. A further virtue of the controller is that alarms can be field configurable (i.e. HIGH “or” LOW) and adjustable. Hysteresis (deadband) can be varied from 1% to 15% of span. It is also facilitated with internal transmitter power supply of 24 V DC, to power up two-wire transmitters.
Low drift precession components are used for long term accuracy of the instruments. All instruments undergo a burn-in for better reliability.
