Remarks:
1. For example: IB-E201F, F stands for function code (communication function);
2, E, F, G, I for the function code, function code can be combined, the following examples:
Temperature Controller Model No.: IB-E201EF, indicates: The temperature controller is an inlaid iron shell temperature control box, and its functions include: general function, 4～20mA current output function (E) and communication function (F).
The E-type thermostat can realize the contact DC function.
3, if there are other special technical or functional requirements, such as Ethernet communication, Profibus communication, multi-channel temperature measurement, fiber optic temperature measurement, etc., can contact us.
