Ordering Code Definition for Manufactured Temperature RS485 Thermostat Analog AI-526

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 or individual, and can be assembled freely. The input type can be set to thermocouple, RTD, or linear current/voltage.

The ordering code of AI-526/AI-526P (V8.2) series instrument is made up of 9 parts. For example:

                      AI-526     A    N    X3    L5    N    S4    -   24VDC  -  (F2)
                                  1         2     3     4      5      6     7                8             9
