4.Product functions
4.1 Switch output DO
4.1.1 Switch output DO description
Switch output DOwith level mode, pulse mode, follow mode (follow DIonly). With the Type C relay output
(normally on and normally closed), the single output supports a maximum load (contact capacity) of 30V/10A or
250V/10A.
Each DO output is designed with an output indicator (red LED indication) indicating that the output port is off.
When the LED is on, it means that the relay is sucked (normally on, normally closed and disconnected); When the LED
is off, the relay is not sucked (normally open, normally closed).
Figure 4-1-1 Switches output DO interface
4.2.2 Switch output DO mode settings
(1) level mode
Depending on the level set by the user, the switching characteristics of the level mode are similar to those of the
self-locking switch.
(2)pulse mode
When the switch output DO is on, the switch output DO switches off automatically after the set pulse width time (in
ms) is maintained. Pulse width settings range from 50to65535(default 50).
(3) Follow the mode
After the user sets the follow mode, set the following input after. The switch output DO side is consistent with the
DI input.
Note: Multiple switch output DO ends can be set to follow one DI input, not one switch output DO side to follow
multiple DI inputs.

4.2 Device address
4.2.1 Device address
Device address composition: Hardware address and software offset address
Figure 4-2-1 Device Address
The device address defaultsto: 32(hardware address 31 plus software address 1 - device address 32).
Device address settings range:1to247.
Hardware address: Implemented by dial switch(5-bit) dial setting (factory default is 31).
Software address: Implemented by the configuration tool software setting Offset Address (factory default is 1).
Example:
If the hardware address is set to 5and the software address is set to 113,the device addressis 118.
4.2.2 Hardware address (dial switch).

Hardware address: The dial switch switches different hardware addresses, and binary represents a 5-digit dial switch.
The "5" direction indicates the low bit and the "1" direction indicates the high bit. Hardware address range adjustable
range 0 to 31.
Hardware Address Dial Settings Description:
Example 1: Set hardware address 0, binary encoding.
Figure 4-2-3 Hardware Address 0
Example 2: Set hardware address 8, binary encoding.
Figure 4-2-4 Hardware Address 8
Example 3: Set hardware address 31, binary encoding.
Figure 4-2-5 Hardware Address 31
Hardware address, can be customized according to the actual situation, the setting method as shown in the above
example.
If multiple devices are required to connect to a single RS485 bus, they can hang on up to 32 devices (just set up a
hardware address) via a hardware address.
If you need more than 32 devices to connect to a single RS485 bus, you need to set up a software address (offset
address) to connect up to 247 devices to a single bus.

After you change the address, you need to power down restart before the new address set is effective.
4.2.3 Software address (offset address).
Software address: Users can make different settings depending on the scene. The software address setting range is 1
to2 24(device address: 1 to 247), and the software address defaults to 1.
After you change the address, you need to power down restart before the new address set is effective.
Changing the software address is done through the configuration tool software, as shown in the figure:
