ماژول مبدل جریان 4-20 میلی آمپر به ولتاژ 0-10 ولت HW-685

توضیحات محصول

Service regulations

1. Power supply: 7-36V (if the output needs to be 10V, the input must be over 12V)

2. After power on, the D2 indicator should be on. Otherwise, please check the wiring.

3. The product has reverse polarity protection.

4. When the current input is at minimum (0mA or 4mA), adjust the Zero potentiometer to make the voltage output to be the minimum value (0.0V or others).

5. When the current input is at maximum (20mA), adjust the Span potentiometer to make the voltage output to be the maximum value (3.3V or 5V or 10V; the output can be as low as 2.5V when the current input is within 4 -20mA).

According to your needs, select the appropriate span through the jumper cap:

ON: jumper cap buckles on the two jumper pins

OFF: two jumper pins without the jumper cap

4 -20mA:

0 -2.5V range:   pin 1, 2 ON    pin 3, 4 ON

0 -3.3V range:   pin 1, 2 OFF   pin 3, 4 OFF

0 -5.0V range:   pin 1, 2 ON    pin 3, 4 ON

0 -10.0V range:  pin 1, 2 ON    pin 3, 4 OFF

0 -20mA:

0 -3.3V range:   pin 1, 2 ON    pin 3, 4 ON

0 -5.0V range:   pin 1, 2 ON    pin 3, 4 ON

0 -10.0V range:  pin 1, 2 ON    pin 3, 4 OFF
