8.2.2 Input Signal
All of Ezi-IO CC-Link IE TSN DIO inputs are photocouplers and there are NPN(N type) and PNP (P type) products
depending on the type of output method of connecting peripheral devices.
•
NPN type (N type): The outputs of connected peripheral devices are NPN open collectors and in the stance of
peripheral devices, current flows in (SINK type)
•
PNP type (P type): The outputs of connected peripheral devices are PNP open collectors and in the stance of
peripheral devices, current flows out (SOURCE type)
The output circuit is based on 24V and the maximum output current is 5mA for each channel. Please check the
standards of peripheral devices before using.
• NPN type (N type) product wiring
If a peripheral device requires power, connect the input of Ezi-IO to VCC(+24V), GND, signal of peripheral devices (3-
wire wiring). If the peripheral device is a simple load like the solenoid valve, connect GND and signal to each end of
the load but if there is a separate power to the peripheral device, only connect the GND and signal. (2-wire wiring)

• PNP type (P type) product wiring
If peripheral device requires power, connect the input of Ezi-IO to VCC(+24V), GND, Signal of peripheral devices (3-
wire wiring). When peripheral devices are simple input points like switches, connect only +24V and signals to each
end of the switch (2-wire wiring).
