Product description:
SWP20 voltage / current conversion module is a miniature plug-in structure conversion module. It will voltage (V or mV), current (mA) signal is converted into a proportion of isolated 1 ~ 5V DC or 4 ~ 20mA DC output signal.
Instrument characteristics
1, the internal use of micro processing for mathematical operations, can be a variety of nonlinear input signal with high precision linear correction. Equipped with SWP20SH display module, the input signal of the corresponding measurement value in digital display and intuitive convenient way.
2, optional AC and DC power supply, the output of the transmission and the host isolation, with a 1 to 5V DC or a to 20mA DC output signal selection and disconnection protection function.
Two, instrument parameters and wiring diagram
MV model SWP-201 202 input voltage / current series of input signal simulation: 3 ~ 100mV V input: 0 ~ 100V DC (absolute value less than 100V) mA input: 0 ~ 20mA DC characteristic parameters set the response time of mV input by the SWP20PCA programmer: About 500ms (time constant), V mA (input: about 100ms time constant) disconnection protection disconnection protection only provides the CMRR of 50Hz with a mV input, more than 120dB wiring diagram A: single input dual input type: B
