Paperless Recorders

I. Paperless recorder overview
     The LU-C5000 series true-color LCD process control paperless recorder supports one to thirty-two channels of programmable PID control and up to one hundred program control curve segments. The instrument uses full-switching universal inputs and can accept thermocouple, RTD, standard current, standard voltage and frequency signals, and can provide transmitter supply output. A micro printer can be connected directly to print real-time and historical data and curves for a user-specified time period; through the RS232 communication interface it can be connected to a portable computer or PDA (personal digital assistant) to read the historical data of the instrument directly, which is then transferred to the computer, where the data management software can analyze, archive and print the acquired data. Through the RS485 communication interface it can be connected to professional configuration software such as KingView and MCGS to form a real-time monitoring system. Modern USB interface technology is also adopted to store data directly on a USB flash drive, extending the recording time.
The paperless recorder has powerful display functions: high-precision bar graph display, real-time trend curve display, historical curve recall, out-of-limit alarm, alarm status display, and intelligent automatic playback of historical trends, making it very convenient to locate alarm points; a positioning playback function is also available for directly querying the data of a year, month, hour, minute and second, quickly and conveniently.
