Frequently Asked Questions

• Q: What type of load can the relay outputs control?
  A: They can switch AC/DC loads up to 2A, such as contactors, solenoid valves, and indicator lamps.
• Q: How is this CPU powered?
  A> It uses a standard 120V or 230V AC line voltage, making it suitable for panel installations without a separate DC power supply.
• Q: Can it connect to a network?
  A: Yes, via its built-in PPI/MPI port. It can also be the master of a PROFIBUS DP network with an additional EM 277 module.
