Frequently Asked Questions
What happens if an output fuse blows?
The red Fault LED illuminates immediately to signal a hardware error. You can identify the specific group through the diagnostic software.
Can I use this for DC loads?
No, the 140DAO84210 is strictly for AC loads. Using DC will damage the internal TRIAC components.
Buyer Guide: How do I choose the right output module?
Verify your total current draw per group. While this module supports 16A total, each group of four outputs must stay under 4A. If your load exceeds this, split the devices across multiple modules to prevent overheating.
