New and most practical products.It can be combined by clients with 8 channels ,each can receive DC 4-20Ma,Mv etc. or AI signal of 1-5V and DI signal of 24V.DC.It can also output AO signal of 4-20Ma and DO signal of  DC 24V.It has all functions of DCS.all operation is by touching screen to finish.

1、 indicating function
       By 5.7”colourful touching screen to show numbers .indicating means are two—4 channel system and 8 channel sysem.

2、controlling function
      In order to be safe and convenient ,the controlling and indicating  part are separated.it has controlling function---by PID .all operation can be finished by operator.Can choose 4 or 8 channel system, both of which ,the first and second channel can be set  to be controlling channel.
3、 schedule alarming funtion
      With up and down alarming  to finish alarming device.on the top of the screen ,it is alarming showing area.pls make notice of the signal input.

4、trendy  recording function
     It has trendy recording functions---3 seconds and 30 seconds of each  with 999 sampling points.30 seconds can keep 50mins.but 30 seconds can keep 8 hours 19mins.
5、concenting function
     it has concenting funtion.the content is as follows:
     Position number:each chart  means a poison number  to be easily chech alarming information etc.
     Unit:inputting units to help to indicate the measuring scope.
     Measuring distance:by setting measuring distance to be digital indicating.the measuring distance should be below 1000.
    Controlling ways:can choose single circuit (one or two);main circuit and vice-circuit.
quatity:4 or 8
Alarming setting:up and down alarming numbers.
Input setting :thread
