When the input is two, three, four wire universal

Two-wire signal, internal distribution DC��V,��mA

Three-wire signal, distribution DC��V,��mA

Four-wire or current source signal, internal resistance ≤���Ω

DA-��/DV-�� Distribution isolator (� in � out)

DR-���/DV-��� Distribution isolation 

distributor (� in � out)

Taking DA-���� as an example, various connections 

of two - and four-wire sensor input are explained

Two-wire sensor direct isolator (sensor without 

external power supply)

DG-���/DV-��� Distribution isolation 

distributor (� in � out)

Two-wire sensor external DC��V power 

supply and then connected to isolator

DG-���/���/DV-���/��� DC Signal isolator (� in � out)

Four-wire sensor or current source signal input

Note: When DA-��/DV-�� is in and out, output � is default.

            Input: Two wire (�-,�+); Three wire (�S,�-,�+); 

                          Four wire (�+,�-)

Note: The default output is an active signal, which can 

             be measured directly with a multimeter.

Note: When the output is three-channel, output � defaults

             Input: Two wire (�-,�+); Three wire (�S,�-,�+); 

                           Four wire (�+,�-)

Note: The default output is an active signal, which can 

             be measured directly with a multimeter.

When the sensor power 

exceeds �W, it is 

recommended to use an 

external power supply. 

Otherwise, abnormal s

ensor operation may occur.

Two wire sensor

Sensors are powered 

by isolators without the 

need for external power 

supply

The input is a two wire 

sensor, such as a 

pressure transmitter, 

temperature 

transmitter, etc
