The working process includes:
- Receiving external 24 V DC power
- Converting input voltage into regulated internal power
- Supplying additional power to I/O modules
- Supporting larger distributed I/O configurations
- Maintaining stable system operation
Main functions include:
- Auxiliary logic power supply
- Distributed I/O power expansion
- Voltage regulation
