WFK2 

Series

(4) NPN/PNP conversion

  NPN and PNP can be converted.

* Perform NPN and PNP conversion when the switch output is OFF. 

Conversion settings are applied when the power is turned back ON.

2. Integrated pulse output

3. Analog output

Pulse output matches the integrating flow count.

Selectable pulse rates

(1) Output conversion

0 to 5 V/1 to 5 V ................... select between 0 to 5 V output and 1 to 5 V output
4 to 20 mA ............................ no output conversion
0 to 10 V/1 to 10 V................ select between 0 to 10 V output and 1 to 10 V output
Applied to instantaneous flow rate, temperature output

(2) Original analog output

 

An analog output function that freely sets the upper and lower limits of normal analog output.

 

* The set range cannot be greater than the max. flow rate of each flow rate range
