SWP20 voltage/current/frequency transforming module is a minitype
temperature transforming module with inserting structure, which
transforms voltage (V or mA) and current (mA) signals into the
insulated output signals of 1~5V DC or 4~20mA DC that are
proportional to the input.
SWP20 voltage/current/frequency transforming module is an
intelligent transmitting module, which can linear-rectify
high-precisely various non-linear input signals by using
microprocessor. It, if fitted with SWP20SH displaying module, can
digitally display the measuring value corresponding to input
signals.
SWP20 voltage/current/frequency transforming module can select AC
or DC electrical source and 1~5V DC or 4~20mA DC output signal. The
transmitting output is insulated with mainframe. It also has
wire-broken protective function.
SWP20 voltage/current/frequency transforming 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.
