Professional FAQ

Q1: How does the FC5-40MR-AC perform in environments with temperature changes?
A1: Field experience shows the FC5 series remains stable in most industrial settings. Good airflow is usually enough.
Q2: Can I drive larger loads with the relay outputs?
A2: For higher loads, using an intermediate relay is recommended. This is a common engineering practice.
Q3: Can expansion boards be replaced without shutting down the PLC?
A3: Expansion boards should be replaced after power-off. Engineers typically back up the program before changes.
Q4: Is Ethernet communication stable for long-term use?
A4: Yes. Using shielded network cables significantly improves long-term stability.
Q5: Will program updates risk losing user data?
A5: USB Type-C upgrades are safe. Still, backing up the project is standard engineering practice.
