Use ESD protection tools during board disassembly, installation and replacement.Verify 24 V DC field power voltage within the normal range before power-on.Check channel LED indicators regularly to judge working status of each I/O point.Clean terminal blocks and board surface every six months to remove dust and oxide.Tighten loose wiring terminals periodically to prevent poor signal contact.Avoid overloading single output channel to trigger overcurrent protection.Inspect internal bus connectors for looseness to ensure stable data transmission.
