1. SUMMARY
1.1 Main Features
● Adopt digital calibration technology for input measurement with non-linear calibration tables for standard
thermocouples and RTDs are available in the instrument.
● Adopt advanced AI artificial intelligence control algorithm, no overshoot and with the function of auto
tuning and self-adaptation.
● Adopt advanced modular structure, with large numbers of output options. Easy installation to shorten
the assembly time in manufacturing line. Maintenance of instruments make easy.
● Friendly and customized operating interface leads to easy learning and simple manipulation. Any
parameter can be promoted to immediate operator access in Field Parameter Table or password
protected in Full Parameter Table.
● With universal power supply of 100-240VAC or 24VDC and various options of installation dimensions.
● ISO9001 (2000Version),high reliability of quality.
● CE certified, complying with EMC requirement, achieving world class level of quality,
anti-interference ability and safety.
POINTS FOR ATTENTION
● This manual introduces AI-518/518P model ARTIFICIAL INTELLIGENCE INDUSTRIAL CONTROLLER
of Version 7.1. Certain functions may not applicable for other versions. After powering on, the
instrument model and software version will be shown. User should pay attention to the version number.
Please read this manual carefully to ensure proper and safe operation.
● Please correctly set parameters according to input / output specification and function. Only correctly
wired instruments with parameters correctly set should be put into use.
● Compared to Version 6.X or earlier versions, some important changes are: New rear terminal
layout,Heating/refrigerating dual output function, and both outputs can be either current or time
proportional output. Alarm applies single lateral deadband; Support up to 4 channels of alarm or event
outputs; Compared with V7.0, AI-518P has 30segments ramps and soaks with dual editable event
output. Adopted advanced X3/X5 high accuracy current output modules instead of X/X4, it makes
higher transmittion output accuracy.
1.2 Ordering Code Definition
Advanced modularized hardware design is utilized for AI series instruments. There are maximum five
module sockets: multi-function input/output (MIO), main output (OUTP), alarm (ALM), auxiliary output (AUX)
and communication (COMM). The input specification can be selected as thermocouple, RTD, or linear
current/voltage.
The ordering code of AI-708/708P/808/808P series instrument is made up of 8 parts. For example:
AI-518 A N X3 L5 N S4 — F2 -- 24VDC
① ② ③ ④ ⑤ ⑥ ⑦ ⑧
It shows that the model of this instrument is AI-518, front panel dimension is 96×96mm, no module is
installed in MIO (Multi-function I/O) socket, X3 linear current output module is installed in OUTP (main
output), ALM (alarm) is L5 (dual relay contact output module), no module is installed in AUX (auxiliary
output), a RS485 communication interface with photoelectric isolation is installed. It has external expanded
input F2(radiant high thermometer), and the power supply of the instrument is 24VDC.Below is all 10
