Head-separated Dual display Digital Pressure Sensor [For gas & liquid] DPC-L100 / DPH-L100
I/O Circuit and Wiring diagrams
DPC-L101
I/O circuit diagram
Notes:
1) |
Set the output load resistance during analog current output to 250 Ω (max.). |
2) |
Note that a voltage of 5 V or higher is generated during analog current output. |
Symbols・・・ |
D1 to D3 : Reverse supply polarity protection diode ZD1, ZD2 : Surge absorption zener diode Tr1, Tr2 : NPN output transistor |
For independent use of sensor head |
Notes:
1) |
When the sensor head is used independently, devices connected to the analog output must have an input impedance set at 10 kΩ or more and load capacity 1,000 pF or less. |
2) |
No short-circuit protection circuit is provided for analog voltage output. Do not connect directly to a power supply. |
3) |
The pressure port and internal circuitry are connected by a capacitor. Do not apply voltage in excess of the specifications’ dielectric strength between the pressure port and wiring. |
4) |
The transparent tube attached to the cable is not used and should be cut off at the base. |
