I/O Circuit and Wiring diagrams

DPC-101

NPN output type

I/O circuit diagram

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 Z_D1 to Z_D3 : 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 Z_D: Surge absorption zener diode
