24V DC Power for PLC and Control Systems
A 24V DC power supply is commonly used as the control voltage in industrial automation cabinets. PLC CPUs, distributed I/O modules, industrial sensors, relays, communication devices, and other control components can depend on a stable DC supply.
The 1606-XLS480E-3 24V power supply can therefore be used as a centralized power source in applications where multiple automation components need to operate from a common 24V DC control supply.
The 480W capacity provides additional power margin for systems with multiple connected loads. Rockwell's technical documentation also specifies short-term reserve capability, with up to 30A available at 24V DC for approximately four seconds.
DIN Rail Installation for Industrial Control Cabinets
The Allen-Bradley 1606-XLS480E-3 supports rail mounting, making it suitable for installation inside industrial control cabinets and automation panels.
Its compact 65 mm width can help make efficient use of cabinet space while providing 480W of DC output power. The unit also includes a DC OK relay contact, which can be integrated into a control system for power-status monitoring.
This feature can be useful in applications where the control system needs to detect a power-supply fault and initiate an alarm, diagnostic action, or controlled shutdown.
