Frequently Asked Questions

• Q: What is the main advantage of the FC5M-40MN-AC over DC-powered models? A: It operates directly on AC 220V power, eliminating the need for an external 24VDC power supply for the PLC and simplifying panel wiring.
• Q: How many high-speed inputs and outputs does it have? A: The FC5M-40MN-AC includes 7 HSC inputs and 6 PTO/PWM outputs, ideal for motion control and high-speed counting applications.
• Q: Can I use both standard and high-speed outputs simultaneously? A: Yes. The unit provides 10 standard NPN outputs and 6 dedicated high-speed outputs. You can configure them independently based on application needs.
• Q: What types of sensors are compatible with the inputs? A: The 24 inputs are sink/source configurable, supporting both NPN (sinking) and PNP (sourcing) sensors, including 2-wire and 3-wire types.
