Great functionality, steep learning curve
Works exactly as described for controlling my garden lights and pump. The documentation could be a bit clearer for beginners, but once configured, it has been running without issues for three months.

Perfect for industrial automation projects
This module integrated seamlessly into our existing SCADA system. The Modbus TCP implementation is stable, and the web interface makes initial setup very quick. Highly recommended for remote switching needs.

Excellent value for money
Compared to other industrial IO controllers, this offers incredible value. The build quality is decent, and the screw terminals are easy to wire. It handles our lab equipment scheduling perfectly.

Robust and reliable
I've deployed six of these units across different sites. They handle network fluctuations well and the relay clicks are solid. The ability to read input states remotely is a huge plus for monitoring security sensors.

Solid hardware, good API
The HTTP API is straightforward to use for custom scripts. I wish it supported MQTT natively, but the TCP socket communication works fine for my Python scripts. Very happy with the purchase.

Solved our remote access issue
We needed a way to reset equipment in a locked cabinet remotely. This 4-channel board did the job perfectly. The latency is low, and the status feedback is accurate.
Q: Does this module support static IP configuration?
A: Yes, the module supports both DHCP and static IP address configuration via the web interface or PC utility software.
Q: Does it come with a power adapter?
A: No, the package includes only the module and terminal block connectors. You will need to provide a separate DC power supply ranging from 9V to 36V.
Q: Is there a delay when triggering the relay over the network?
A: Under normal LAN conditions, the response time is typically less than 50ms. Latency may increase slightly depending on network congestion and distance.
Q: What is the maximum current rating for all channels combined?
A: Each channel is rated for 10A. However, please ensure the total power supply and PCB trace limits are not exceeded if all relays are activated simultaneously under heavy load. We recommend keeping the total continuous load under 20A for safety.
Q: Can I control the relays using a smartphone?
A: Absolutely. Since the device connects to your local network via Ethernet, you can access the web interface from any smartphone browser on the same network, or use a third-party Modbus app.
