to minimize voltage drops.
• Use twisted pair cable to minimize noise effects.
Proper compressed connection terminal
• Circular type terminal (O type Lug)
• Circular type terminal with insulation resistance

Power supply system
Use separate wiring systems for the PLC module, I/O module, and
power supply module as shown in the following diagram.
Use isolation transformer for noisy environments
• Use a low noise power supply.
• Use an isolation transformer to reduce the noise as illustrated above.
