Products > Paperless Recorder > PAPERLESS RECORDER


AI series multi-channel paperless recorder inherits from Yudian’s various famous technologies. It integrates measurement, display, alarm, data logging into one slim instrument. It supports maximum 6 inputs with three different size panel, 5 inch, 7 inch and 9 inch. The thickness of 9 inch recorder is only 38mm which can be easily installed in various kinds of equipment. Main parameters are set in one single interface through the newly industrial graded touch screen.


l With 0.1%FS measuring accuracy, support multiple input signals such as thermocouple, RTD, voltage, current and etc, and supportextended input specification and user-  define nonlinear calibration table.

l Armed with standard PID and AI PID intelligent control algorithm function and advanced artificial intelligence adjustment, self-tuning, adaptive, precise and stable controlling ability. 

l AI-3559/3759/3959 series support output of three-phase three-wire phase shift trigger, forward and reverse of valve, framing or proportional adjustment, etc.

l AI-3556P/3559P/3756P/3759P/3956P/3959P series have ramp soak program control function and adopt artificial intelligence algorithm to gain good controlling ability.

l Low power consumption. Can provide up to 12 months free warranty. ARM chip in dual CPU mode is used to process graphical man-machine interface and data logging function; Individual single chip CPU ensures real time control and sampling, fulfilling strict industrial site requirements; has passed the anti-interface test of 4KV/5KHz burst of pulses.

l Provide data recording and alarm logging functions in the form of reports along with real time trend curve, bar graph and history trend curve. Supports downloading data through USB for further processing on the computer.  

l Embedded with Ethernet socket providing remote monitoring and operation through internet cable.

l There are four internal slots, available for customizing functions by freely installing various modules of analog and digital inputs and outputs.

l When the instrument's own module combination can't meet the customer's requirements, then can connect various types of Yudian temperature modules, switch modules I/O or PLC through the expansion port and up to dozens of measurement and monitoring circuits.

l Programmable module input, supporting thermocouple, RTD, mV, mA  and two-wire transmitter. 0.2% measuring accuracy. Each channel can have independent input specification, with squre-root, multiplication, addition and subtraction. All channels are equipped with digital adjustment and filtering functions. Each channel has individual digital adjustment and filtering parameters. It provides wind speed and atmospheric pressure constant compensation. By inputting dry-wet Pt100 blub, surrounding temperature and humidity can be obtained.

l Decimal place, display resolution, digital filter, input off-set of each input channel can be set.

l High performance hardware greatly reduces the temperature drift and the interference between various channels so as to increase accuracy and anti-interference as same level of that of single channel one.

l Low power consumption. 36 months warranty on quality. HMI graphic and data logging are process by one ARM chip in dual CPU mode. Individual single chip CPU ensures real time control and sampling, fulfilling strict request on field. Anti-interference test 4KV/5KHz burst of pulses passed.

l Real time trend graph, bar graph and history trend is provided. History record and alarm record can reviewed in the data-logger itself or exported to external USB storage device. The storage size is 150MB.

l There are 5 internal module slots, available for user customization of function modules such as inputs and alarm modules.

l Extended socket connecting Yudian temperature control instruments, I/O devices, PLC, etc.
