for sensor
When connecting to the voltage output type (1) sensor, avoid the wiring as shown below.
In the wiring below, a current flows into the DC input module through the pull-up resistor (2) in the sensor. As
a result, an input current may not reach the ON current of the DC input module (3), which does not change the
input signal to an ON state.
