Function：：       ： 

     The functions of the double-channel distribution are signal distribution 、signal transform and signal isolation.

Distribute :  The signals from instruments such as flow meter, transmitter, transducer ,are needed not only to local show but also to export to other controlling systems such as PLC 、DCS  and environmental monitoring systems ,they must to be distributed; in the other hand when the control systems such as PLC, DCS Environmental monitoring system output signals to control several equipments ,the signals from them are also needed to be distributed.

Transform : When the signals from instruments are non-uniform ,some of them should   be changed. For example, the RTD should be changed  into 4~20mA.

Isolation ：All the signals from equipments are needed to be isolated ,in order to guarantee that they are safety and  accurate. So isolation is essential.

Applicable occasion ：

      1、 An analog signal is needed to distribute into two analog signals.

      2、After the signals from field device are isolated ,they are inputted into monitoring systems such as DCS、PLC to improve systems security.

      3、When RTD or thermocouple's signals need to be changed into current signals ,such as 4~20mA,we can  use the temperature transmitter.

      4、 When we want to get  the signals from two-wire instruments, we have to

 offer it DC24V power, so we should select the signal processors with DC24V power out.
