4.2.1 Wiring consideration for different Input devices (sensor/ switch…)
DC input
Example
．
1 DC 2 wires type (proximity sensor):
Example 2
．
Contact output type
Example 3
．
NPN open collector type
Example
．
4 PNP open collector type
Example 5
．
NPN current output type
Example 6
．
PNP current output type
Example 7. Voltage output type
Among the above example 1, 2, 3, 4, 5, the driving current of external output transistor must be
larger than that of internal transistor of input module (6～7mA).
As for example 1, please pay attention to leakage current as OFF (if that is larger than OFF current,
the OFF action will not be operated).
As for example 7, the component of voltage output type can not be used in TP03 DC input.
