with parameters correctly set can be put into use.
1.2 Ordering Code Definition
Advanced modularized hardware design is utilized for AI series instruments. There are maximum five module slots:
multi-function input/output (MIO), main output (OUTP), alarm (ALM), auxiliary output (AUX) and communication
(COMM). The modules can be purchased together with or separately from the instrument, and can be assembled
freely. The input type can be freely set to thermocouple, RTD, or linear current/voltage.
The ordering code of AI-518 series instrument is made up of 9 parts. For example:
