Transistor output
For connection to binary inputs of a PLC with an
input resistance < 100 kΩ.
If the input of the PLC is high-impedance, you have
to connect a load resistor (R
L
) with 100 kΩ
according to the following illustrations in parallel to
the input of the PLC.
For the plug version valve plug ISO 4400, standard
cable with round wire cross-section can be used.
Cable diameter 4.5 … 7 mm, protection IP 65.
The M12 x 1 plug connection requires a complete
confectioned cable with plug.
