Detail:
SWP20 series of temperature change module is a kind of small size of the plug-in structure of the temperature change module. It will come from the thermocouple electromotive force or thermal resistance resistance value transformation become isolation ratio of 1 ~ 5V DC or 4 ~ 20mA DC output signal and the temperature.
One, instrument features
1, the internal use of the microprocessor for mathematical operations, can be a variety of nonlinear input signal processing. Equipped with SWP20SH display module, the input signal of the corresponding temperature value to digitally display intuitive convenient.
2, two power supply, the output signal of the 1 ~ 5V or 4 ~ DC output signal is selected, which has the function of selecting the output signal of ~ DC 20mA or the host.
Two, instrument parameters and wiring diagram
Model
SWP-201 202 thermocouple / thermal resistance series
Input signal
--B, S, K, E, WRe, J, T, etc.
Electrical resistance: standard platinum thermal resistance: Pt100, 3 wire connection
Standard copper thermal resistance: Cu50, Cu100,3 wire connection
Characteristic
Set the parameters set by the SWP20PCA programmer
Response time is about 500ms
Wiring diagram
A: single path Thermocouple Input Type B: single path heat resistance input type
C: two way Thermocouple Input Type D: two way heat resistance input type
Pay attention to:
1, external connection terminal for M3.5 screw. The use of non welded connections.
2, in the external should set the power switch and fuse. The use of 0.5A fuses (DC 24V power supply with fast fuse) is recommended.
3, the instrument has a flow protection function, which can prevent the internal power short circuit caused the instrument damage.
4, without the use of the first output, the first output terminal.
5, in the circumstances of the impact of the lightning, please install special lightning arrester.
