> Introduction ::

Pantech's Electronic Dual Indicator cum Controller, model 807 is an ideal instrument for providing indication as well as controlling set points to dual channels simultaneously. It is designed to accept various process inputs (Current, Voltage, RTD, and Thermocouple) on both channels, display the same and generate potential free contacts when abnormal conditions occur. The model is equipped with an optional analog output facility on both channels (Isolated or non-isolated).

Model 807 is an analog electronics based controller. It is capable to display the both process values to the resolution of maximum 3 ½ digits and can be designed to generate maximum of 2 nos. of potential free contacts on each channel. 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 on each channel, 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.
