Remark：
1、like：One-l201f，L代表壁掛式鐵殼溫控箱，F(xiàn) is the code name for communication function；
2、E、F、G、I均為功能代碼，F(xiàn)unctional codes can be combined，The following examples are given：
Thermotor model：One-l201fg，express：溫控器為壁掛式鐵殼溫控箱，Its functions include：General functions、Communication function (F)，并增加一路機房環(huán)境溫度測量與控制功能(G)。 該型號功能組合可定制，如有其他功能需求，具體可和我們電話聯(lián)系。
3、If there are other special technical or functional requirements，Such as Ethernet communication、Profibus Communication、Multi-channel temperature measurement、光纖測溫、擴展觸點容量等，You can contact us。
