Perfect for my automation project

This relay module worked flawlessly with my PLC setup. The optocoupler isolation gives me peace of mind, and the LED indicators make troubleshooting very easy. Highly recommended for industrial control applications.

Solid build quality

The terminals are sturdy and hold wires well. I bought the 8-channel version for a lighting control system. Only minor issue is the mounting holes could be slightly larger for easier DIN rail installation, but overall a great product.

Great value for money

Compared to other brands, this offers excellent performance at a lower price point. The switching is crisp and silent enough for my workshop environment. Will definitely buy more channels if I expand my system.

Reliable signal amplification

Exactly what I needed to amplify weak signals from my sensor array. The 24V option works perfectly with our existing infrastructure. No noise issues detected so far after two weeks of continuous operation.

Industrial grade performance

We deployed sixteen of these units in a factory setting. They have been running 24/7 for a month with zero failures. The isolation prevents any feedback into the controller, which was our main concern.

Good for prototyping

Used this for a quick prototype and it handled the load without heating up. The documentation could be a bit clearer on the jumper settings for high/low trigger, but once figured out, it works great.

5 FAQ

Q: Can I mix 12V and 24V inputs on the same board?

A: No, the entire board is designed to operate at a single control voltage level (either all 12V or all 24V depending on the model purchased). Mixing voltages can damage the optocouplers and void the warranty.

Q: Is the output normally open or normally closed?

A: The default configuration is Normally Open (NO). However, each relay has Common (COM), Normally Open (NO), and Normally Closed (NC) terminals accessible via the screw blocks, allowing you to wire for either mode.

Q: What is the maximum current rating for the common terminal?

A: While each channel is rated for 10A, the total current through the common terminal should not exceed the sum of the active channels, keeping within safe thermal limits. We recommend not exceeding 20A total across all channels simultaneously for longevity.

Q: Can this module be used with a 5V Arduino signal?

A: Yes, but you must ensure the input voltage matches the control voltage version you purchased (12V or 24V). If using a 5V microcontroller, you may need a level shifter or select a specific 5V logic compatible model if available.

Q: Does this come with a DIN rail clip included?

A: The standard package includes the relay board and screw terminals. DIN rail clips are sold separately, but the board has pre-drilled holes compatible with standard universal DIN rail adapters.
