Multi-loop Survey Display Controller

1.Brief Introduction ZY-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 effetive. ZY-905M 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.2.
