Professional FAQ

• When should I choose non-isolated design?

Choose it when all field devices share same ground.
It lowers cost.
Do not use in high noise area.

• How do I check load compatibility?

Check output loop resistance.
Make sure total load is below 550 Ω.
Add margin for cable length.

• Is this module good for small plants?

Yes.
It is compact.
It fits simple control loops.
Good for water and utility systems.

• What should I confirm before replacement?

Check model code.
Check wiring layout.
Confirm power rating.
Verify channel count.

• How to reduce signal error?

Use shielded cable.
Keep cable short.
Avoid running near power line.
Check grounding point.
