Figure 4-3 Connect to PNP Device
NPN Device
When connecting the main module to NPN device, it is recommended to use 4.7 kΩ pull-up resistor.

Opto-Isolated Output Wiring
The opto-isolated output of the main module can output NPN or PNP signal. Regarding opto-isolated
output, different output electrical level types correspond to varied voltage ranges.
Note
When the main module's output connects external devices, the voltage range of EXT is from 7 V to
24 V, and the output current of each pin cannot be larger than 40 mA.
●
When the output electrical level type is high electrical level, the voltage range is from EXT-0.3 V
to EXT voltage value.
●
When the output electrical level type is low electrical level, the voltage range is from 0 V to 0.4 V.
