II. Overview

    The LU-show series intelligent paperless recorders combine recording and control in a single unit and provide fully switchable universal inputs: thermocouple, RTD, standard voltage and standard current signals. Output control modes include PID control, on/off control, auto-tuning control and manual control.

     The LU-show R/C3200 can accept 1 to 16 PID control channels or 1 to 32 signal inputs; each control board has independent signal input, main output and alarm output, with full isolation between inputs and outputs. Programmable PID control provides program curves of up to 100 segments. Transmitter supply output is available.
    Flexible data storage modes: the recorder has a built-in 512MB storage space, and each channel has an independently adjustable recording interval (1-3600 s); users can select channels and recording intervals as required for data storage. A high-capacity FLASH memory chip stores historical data with retention after power failure, and the internal storage time can reach 95.5 days to 941 years. With USB interface technology, data can be transferred directly to a USB flash drive for longer recording time.
    Convenient data processing: screenshots can be copied directly to a PC for printing, and data and curves for a user-specified period can be printed; the communication mode is selected intelligently, and RS232 MODBUS RTU, RS485 MODBUS RTU or LAN MODBUS TCP can be configured without opening the housing; connect to a portable computer or PDA via the RS232 interface to upload real-time/historical data directly, and use the host computer data management software or USB flash drive utility software to analyze, archive and print the data; the instrument can also connect via the RS485 or LAN (Ethernet) interface to professional SCADA systems such as KingView and MCGS.
    Powerful display functions: overview screen, extra-large screen, bar graph screen, real-time curve, control process screen, historical curve, alarm screen, system configuration screen, channel configuration screen and print setting screen, etc. All curve screens support zooming, with an intelligent automatic playback function for historical trends featuring time and amplitude zoom, making alarm points extremely easy to find; a positioning query function allows direct queries of data for a specific year, month, day, hour, minute and second; the tag display function lets users name channels as desired.
   Rich alarm outputs with 9 alarm modes that can be freely configured.
   Chinese/English bilingual switchable display interface.

2. Measurement input signal parameters

     The LU-R/C3200 and LU-show R/C2200 process control paperless recorders allow direct input of many signal types, with full isolation between channels and an isolation voltage greater than 400V. Input signal types include: 0~10mADC, 4~20mADC, 0~5VDC, 1~5VDC, thermocouples (B, E, J, K, S, T, Wre325, N), RTDs (Pt100, Cu50, Cu100), etc.
The signal types are as follows:

        Type II:                0~10mADC, 0~5VDC;
        Type III:                4~20mADC, 1~5VDC;
        K-type thermocouple:           0°C~1300°C;
        S-type thermocouple:           0°C~1700°C;

        T-type thermocouple:          -200°C~400°C;
        E-type thermocouple:          -200°C~1000°C;
        J-type thermocouple:          0°C~800°C;
        Wre325-type thermocouple:     0°C~2300°C
        N-type thermocouple:          0°C~1300°C
        Pt100:              -200°C~600°C;
        Cu50:               -50°C~150°C;

 0-10mADC current (RL<1000Ω, extendable to 2000Ω);

 0-20mADC current (RL<500Ω, extendable to 1000Ω);
0-22mADC custom current (freely set by software);
solid-state relay drive (12V/50mADC);
relay contact output;
SCR zero-crossing trigger output (single-phase, three-phase);
24V power distribution: current <200mADC.

4. Historical data storage

    The storage space for recorded data is dynamically adjustable, and each channel has its own independently adjustable recording interval; each channel can be enabled or disabled individually. The fewer channels that are enabled and the longer the recording interval, the longer the historical data that can be recorded, and vice versa. The internal FLASH storage space for recording channel history data is 512M; how long recorded data can be retained depends on the number of enabled channels and the recording intervals of those channels, ranging from 95 days to 941 years.
