1.2 Model definition.

Advanced modularized hardware design is utilized for C18 series instruments. There are maximum five module slots: output, alarm, communication and other functions can select the appropriate module on demand. 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 C18 series instrument is made up of 9 parts. For example:

It shows that the model of this instrument is C18, front panel dimension is A size(96 ×96mm), no module is installed in MIO slot, 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), S4 (RS485 communication interface module) is installed at COMM , and the power supply of the instrument is 24VDC, an extended input type (F2 radiation type pyrometer) is available
