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.
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.

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.
