原理HT375通信器是一種便攜式的終端,它與采用HART通信協(xié)議的儀表一起使用,對(duì)其進(jìn)行設(shè)定,更改和顯示,它可監(jiān)控輸入/輸出值和自診斷結(jié)果。設(shè)定恒定電流的輸出和調(diào)零。 當(dāng)系統(tǒng)開動(dòng)或維持操作時(shí),只要把HT375型HART通信器接在4~20mA通信信號(hào)線上,就可以使用
功能特點(diǎn)在線監(jiān)控和通信通信期間,調(diào)制信號(hào)不會(huì)中斷4~20mA DC信號(hào)-與采用HART通信協(xié)議的儀表可共用HT375型HART通信器能與采用HART通信協(xié)議的所有儀表一起使用-操作方便大顯示屏幕(4行,每行18個(gè)字符),采用中文顯示,用戶看了一目了然,設(shè)定和更改方便-信息自診斷/保護(hù)功能自檢查功能格式化密碼保護(hù)低電壓報(bào)警顯示
