4.3.2 Digital Input (DI)
Fig 4-8
The electrical cabinet is equipped with 16 digital PNP type input(Active high) (DI1 ~ DI16) to support
isolated signal input. The level signal satisfies the IEC61131-2 (Type1/2/3) standard and is used to detect the
input signal level status.

The V+ interface supports external 10~35V power input. The factory default uses internal 24V power
supply. The high level range is 15~24V, and the low level range is 0~11V.
Users can also connect DIx to V+ directly.
Different types of input signals have different connections. The specific connection methods are as follows:
a) Dry contact signal as input
Figure 4-9
During dry contact input, one of the wires is connected to V + and the other wire is connected to DIx. When
the circuit is on (as shown in the figure, the switch or relay is closed), the corresponding LED turns on. You can
also see the DIx status on the APP interface
b) PNP type signal as input
