Great value for money
Does what it says on the tin. Good price point for a multi-channel module compared to competitors.

Good but documentation could be better
The hardware is solid, but the pinout diagram in the manual was a bit unclear. Once figured out, it works well.

Reliable for industrial use
Works great with our existing PLC setup. The MODBUS implementation is stable and we haven't had any dropouts.
5 FAQ
Q: Is this module compatible with Siemens PLCs?
A: Yes, as long as the PLC supports MODBUS RTU over RS-485, it should be compatible.
Q: Can I daisy chain multiple modules on the same bus?
A: Yes, you can daisy chain multiple devices using the standard RS-485 topology.
Q: Does this version include galvanic isolation?
A: This standard version does not include isolation. Please check our isolated series if you require that feature.
Q: What is the maximum communication distance supported?
A: Standard RS-485 specifications allow up to 1200 meters depending on cable quality and baud rate.
Q: Do I need to purchase the configuration software separately?
A: No, the software is included in the package download link provided in the manual.
