✅ Typical Load Combination Reference (5A Capacity)

S7-1200 CPU + 8~16 DI/DO points + HMI + several proximity/photoelectric sensors + 2~4 pcs 24V solenoid valves + safety relay.

Atenţie: Solenoid valve has high inrush current, reserve margin during selection; High-power valves require separate power loop.

⚠️ Not Recommended Applications

1. High-power 24V motors, heavy heating loads (This is control power supply, not power supply for high power loads)
2. 3-phase input system (unless single-phase power is tapped from front end)
3. Heavy corrosion environment, direct outdoor exposure (must be installed inside control cabinet)
4. Direct installation in hazardous explosive area
5. Main power supply for large systems (10A+ model or redundant scheme recommended)

✅ Selection Key Points

Avantaje: Power-good relay output, 150% short-time overload capacity, compact DIN rail mounting, SELV safety isolation, ideal for small control cabinets requiring power status monitoring.
