Martens 放大器 TV125M / ST125M 隔離放大器 Martens of the GHM GROUP
TV125M / ST125M系列的隔離放大器適用于電位分離或轉(zhuǎn)換標(biāo)準(zhǔn)信號。輸入和輸出的通用設(shè)計以及具有寬范圍電源的內(nèi)部電源使得*具有一種類型的設(shè)備的廣泛應(yīng)用成為可能。
或者，電源可以通過安裝導(dǎo)軌總線連接器進(jìn)行。可插拔的端子排允許簡單且省時的布線。
輸入和輸出信號的配置由前面板DIP開關(guān)以非常簡單和快速的方式完成。
由于微處理器的設(shè)計，可以解釋測量范圍的下沖或超出，并通過前面板上的雙色狀態(tài)LED報告。如果出現(xiàn)錯誤，則將輸出設(shè)置為定義的初始值或結(jié)束值。
測量范圍的初始值和結(jié)束值可通過兩個前置式修剪器進(jìn)行調(diào)整。
ST125的設(shè)備版本還為外部2線，3線和4線傳感器提供發(fā)射器電源。
