4800 固定式控制主機
兼功能強大完整的控制主機

- 提供單點單sensor或雙sensor,本機或遠端sensor最遠可達200米
- 每一個sensor都提供標準4-20 mA類比輸出或ModBus RTU數位輸出
- 超亮LED雙channel顯示
- 可選購本機relay接點
- 可使用磁棒做非侵入式校正
- 鋁製防爆外殼
下一世代的 iTrans?固定式氣體偵測器可提供單點一個或兩個sensor,可提供使用者在安裝上最大的彈性、最好的效能和最低的安裝成本。四線系統透過RS485 bus架構可串接最多200 transmitters,使用"smart" sensor技術,可提供sensor自動辨識、歸零、校正錯誤保護、安全密碼保護,並以鋁製防爆外殼包覆。
透過微處理器控制的transmitters可提供獨立運作工作或是透過標準4-20 mA類比輸出或ModBus RTU數位輸出連接到任何控制主機或是PLC。透過選購的本機relay接點,不需透過控制主機,偵測器可獨立運作,啟動警報、風扇或是關閉整個系統。
iTrans也提供relay關閉功能,以避免在校正時啟動任何被控設備。
