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