NPN output type |
Notes:
1) | Select and use the auto-reference function and remote zero-adjustment function. |
---|---|
2) | Set the output load resistance during analog current output to 250 Ω (max.) |
3) | Note that a voltage of 5 V or higher is generated during analog current output. |
Symbols・・・ | D1 to D4 : Reverse supply polarity protection diode ZD1 to ZD3 : Surge absorption zener diode Tr1, Tr2 : NPN output transistor |
---|
*1
For independent use of sensor head |
Notes:
1) | In case the sensor head is used independently, insulate the white lead wire (terminal No.4) and keep it open. |
---|---|
2) | When the sensor head is used independently, devices connected to the analog output must have an input impedance set at 50 kΩ or more. |
Symbols・・・ | D : Reverse supply polarity protection diode ZD: Surge absorption zener diode |
