Pantech's Programmable Universal/Predefined input Scanner, model 890 is an ideal instrument for providing indication as well as controlling set points for various multiple processes. It is designed to accept various process inputs (Current, Voltage, RTD, and Thermocouple) simultaneously (or predefined) with facility of all inputs onboard field configuration, calibration and displaying the same. Two scanning modes are provided AUTO/MANUAL. It is normally designed to accept UPTO 32 different channels simultaneously. The instrument allows CHANNEL TO GROUP fixings, RELAYS to GROUP fixings . Detailed functions and configurations regarding these are explained beneath. The model is also equipped with an optional 4 analog outputs facility (Isolated or non-isolated). The model has optional in built RTC for providing timed data. The scanning time can be adjusted from 1 second to 99 seconds maximum through front keys. Unused channel SKIP facility is also provided in all versions. It can be optionally equipped with serial/parallel communication facility of different open protocols. In an extended version the same scanner can also be used as a DATA LOGGER with all the capabilities of a multi channel dataloggers ( Refer Model no. 891 ). The high end microprocessor program ensures the best and easiest possible user interactive modes. The EASE felt by the user in configuring the scanner is the real essence of product. Low drift precession components are used for long term accuracy of the instruments. All instruments undergo a burn-in for better reliability
