1.2 Model definition.

Advanced modular hardware design is utilized for Temperature Controller series instrument. The instrument with enhanced lateral plate can be equipped with maximum modules of 5.There are more than ten kinds of modules, some of which are double-duty module. Modules of special function can be customized on request.

The basal Temperature Controller instrument has provided many functions enough to meet different requirements asked by users. In order to expand its application bound, an optional software function is provided. The options make the instrument to be able to meet some users' special requirement. There is another manual about these options for those users with special requirement.

The type number of Temperature Controller series instrument is made up of 10 parts, for example:

It shows that the basal function of this instrument is C18 type, front panel dimension is 96×96mm, main output is linear current output without isolation, alarm 1 is relay contact output module, alarm 2 is not installed in, a RS485 communication interface with photoelectric isolation is installed. It is equipped with enhanced lateral plate, auxiliary output is relay contact output module. Optional input type (F2 radiation type pyrometer) and No.3 software function are also available
