When the PLC output goes high, the F4901 energizes, connecting the battery to the fan.
Battery 24V (+) ---- [COM] [NO] ----------------- Fan (+) Fan (-) ----------------- Battery GND
A1: Yes, absolutely. A power supply's current rating is its maximum capacity. Your 5A device will only draw the 5A it requires. However, going the other way (using a 5A supply for an 11A load) would be dangerous and cause the supply to fail. f4901 11a 24v schematic install

Logic-level or direct 24V trigger (model dependent) Contact Type: Usually SPST or SPDT 2. Understanding the Schematic
After completing the , perform these tests: Your 5A device will only draw the 5A it requires
Actuator does not move when thermostat calls for system operation. Loss of primary 24 VAC power supply.
The numbers below reflect standard industrial and automotive relay terminal naming conventions (ISO 7588). Check your specific casing diagram to confirm matching numbers.
