Modbus 8/16/32 Analog Input and Output Network Remote IO Controller
Module
Product Description:
The Remote IO Module is a powerful industrial remote control
device, designed to provide up to 4 input and 4 relay output
channels. It features an 80mm*71mm*63mm compact size, making it
ideal for a wide range of industrial control applications. With a
12~24V DC power supply, it is capable of providing reliable digital
inputs, as well as secure and efficient relay outputs for remote
control operations. With its robust and reliable design, the Remote
IO Module is the ideal solution for any industrial remote control
needs.
Features:
Our product supports MODBUS RTU protocol, which allows for cascading, so the number of IO interfaces can be
non-inductively expanded without configuration. Plug and play, no setup is needed. Our
product is capable of adaptive master-slave station and register
address. What's more, the communication delay is as short as milliseconds, and no packet loss or abnormality can be found in high-speed
communication. On the top of that, the hardware indicator light reflects the communication status in real time.

Easy to USE:
- ET1020 are connected end to end (the M port is connected to the S
port), and the first ET1020 is the master station.
- Dial the communication address (dial code 1-5) of each ET product
to a different position to avoid communication conflicts.
- Connect the power supply of the master station and the RS485
communication line, and then communicate with the master station
through MODBUS protocol.

FAQ:
① Q: Why AI Data acquisition is normal, but the control AO will be
wrong?
A: Please check the address code of the cascade module, it cannot
be consistent.
The address code does not affect data collection, but it will
affect downlink control.
② Q: Why are 4 ET1020 modules connected and read 16 channels?AI
will report an error?
A: Please read the 1000H-1002H register data first to determine how
many slave IOs the master module has detected. If it does not match
the actual situation, you can find the problematic module according
to the Alarm light. The Alarm light is always on, indicating that
the communication of the lower-level module is abnormal.
③ Q: I have 8 modules. If there is a communication problem with one
module in the middle, will the subsequent modules be unable to
communicate?
A: Yes, the cascading of the modules is similar to the high-speed
rail carriages, which are disconnected in the middle, and the
high-speed rail head will only pull the remaining carriages
forward. The adaptive algorithm of the main module can ensure
timely detection of abnormalities: when requesting IO of abnormal
modules, an error will be replied, and the remaining modules will
work stably.
④ Q: I have 4 modules that are already working normally, and want
to add 2 more, how do I do it?
A: Direct cascading, only need to ensure that the address code is
inconsistent, the main module can be self-adaptive.
⑤ Q: How many modules can be cascaded at most?
A: The default firmware supports a maximum of 10, if you have
special needs, feel free to harass customer service.
⑥ Q: Is it considered to introduce modules of other interface
types, and the protocols are compatible with each other?
A:The answer is yes.
