Installation Guidelines
Follow these steps to install the TC-FOD321 correctly.
First, ensure the DIN rail is clean and securely fastened. Next, clip the module onto the rail until it locks. Then, connect external DC power within the 10-31.2Vdc range. Meanwhile, verify that the total current per group does not exceed the limits (6A for channels 0-15, 8A for channels 16-31).
For wire connections, use 12-gauge stranded wire. Strip the insulation carefully to 1.2mm maximum. Also, make sure the wire temperature rating is 75°C or higher. Finally, check the yellow status indicators after power-up. Each channel lights up when active.

Frequently Asked Questions (FAQ)
1. Can I connect different voltage loads to the TC-FOD321?
Yes, you can connect loads ranging from 10Vdc to 31.2Vdc. However, ensure the load current stays below 500mA per channel.
2. What happens if a channel exceeds 500mA?
The module’s protection limits the current. Extended overload may cause the channel to shut down temporarily. Reduce the load to restore normal operation.
3. Is isolation provided between individual channels?
No, channels are non-isolated within each group of 16. Therefore, you must consider common voltages inside the same group.
4. Which shipping carriers do you use?
We ship using Fedex, UPS, and DHL. Delivery times vary by destination. Contact us for a tracking number.
5. How do I check if a specific output is working?
Look at the yellow channel status indicators on the front panel. Each LED lights up when its corresponding output is ON.
