The LU-R1200 series intelligent paperless recorder combines recording and control in a single unit and provides 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-R1200 can accept 1 to 2 PID control channels or 1 to 4 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 total of 64M of internal storage space, and each channel has an independently adjustable recording interval (1-3600 seconds); 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 191 days to 1882 years. With USB interface technology, data can be transferred directly to a USB flash drive for longer recording time.
Connect to a portable computer or PDA via the RS232 communication 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, 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.
The modular design makes configuration more flexible; different acquisition boards can be used at the same time, and the electrical isolation between inputs and outputs minimizes interference from power supply radiation on the acquisition boards and main board, greatly improving instrument reliability. The user-friendly HMI provides operating hints on every screen, so users can operate and use the instrument easily without special training. A Chinese/English bilingual display interface is also provided.
