1. Brief Introduction
LU-905M is suit for multi points measuring display and control system. It can tour examine and display multi-channels signals, may has two circuits public alarm outputs which can be set willfully to upper limit alarm or lower limit alarm. You can willfully shied one or some circuits of the alarm function and let other circuits effective.
LU-905M may shield survey and display of any one or some input channels, it has two display methods, can automatically tour-display the PV of each circuit and also can fix-display only one of the PV. The interval for each circuit display can be regulated when automatically tour-display the PV.
