FAQ
- Can I use inductive loads per channel?
Use inductive loads within the listed contact ratings.
If switching coils, install suppression devices. - How do I test relay outputs safely?
Power the module in a test bench.
Trigger outputs one by one and observe LEDs. - How often should I inspect the module?
Inspect during planned shutdowns.
Check LEDs and wiring every six months. - What reduces interference on long runs?
Use shielded cable and ground shields at one end.
Route power cables separately from signal wires. - How do I handle a stuck relay?
Remove power first.
Check wiring and relay contacts.
Replace module if fault persists.
