SWP20*DL type of power distributing module is a minitype
transforming module for power distributing with inserting
structure. At the same time it provides voltage for two-wire-system
transformer, it receives 4~20 mA DC output signals from
transformer, which are proportional to differential pressure,
pressure, liquid level, and so on.
SWP20*DL type of power distributing module can select AC or DC
electrical source and 1~5V DC or 4~20mA DC output signal. It is
collocated with transformer power switch. The transmitting output
is insulated with mainframe.
SWP20*DL type of power distributing module also has a channel of
serial communicating output, which can select RS-232, RS-485 or
RS-422 communicating interface. The communicating output is
insulated with mainframe.
4~20mA DC (from the output of two-wire-system transformer supplied
by 24V DC)
·INPUT CHANNEL: 1 channel, which can be connected with one
·INPUT RESISTANCE 250Ω
·WIRE RESISTANCE (wire that connects transmitter with power
(1)18V is the minimum power voltage, which is the difference of 24V
and voltage drop within transmitter (6V). (2)MWV is the minimum
working voltage of transmitter, which for diffused silicon is 12V
·OUTPUT: two-channel output insulated
The first channel: 1~5V DC or 4~20mA DC (selectable)
The second output: serial communicating output with RS-232, RS-485
or RS-422 communicating interface
·LOAD RESISTANCE: less than 250Ω(if output is 1~5V DC)
·ALLOWABLE LOAD RESISTANCE: 0~600Ω(if output is 4~20mA DC)

V or mA input: about 100ms(time constant)
·CO-MODULE SUPPRESS RATIO: more than 120dB when 50Hz
·INSULATING: input, the 1st output, the 2nd output and electric
source is insulated from each other.
