Detailed Product Description

AOB706 multiplex polling display alarm can in-process check and alarm control the industrial process parameters including temperature, pressure, discharge, liquid level and humidity etc. Also it is fit for analog quantity data collection module in computer monitoring system or LC and can supply the switching value input or output  interface to PC for switching value operation.
The key features include:

 1.Fixed-point/automatic polling measuring display function.
 2. Can support most six programmable measuring input circuit and input six ways of thermocouple, voltage or current signal assorted with different input modules. When the input is resistance thermometer detector, it can support six ways of  two-wire system connection mode or three ways of  three-wire connection mode.
 3. Each input circuit can switch freely among congeneric scale division marking and each circuit has the independent digital filtering and correct system.
 4. Each circuit is provided with independent higher and lower limit alarm function and the alarm output position can be programmable designate. The higher or lower limit alarm signal of different input circuit can be programmed as both the same alarm passage output and different passage output. UP to eight ways of alarm output are supported.
 5. Eight ways of switching value input or output are provided as switching value IO port  controlled by PC.
 6. Three ways of DC current transmitting output are provided and the transmitting output  target and output specifications can be defined freely.
 7. Two ways of DC24V feeding output for external transducer and other circuitry.
 RS485 serial communication and adopt MODBUS_RTU communication protocol.
