System Architecture & Signal Flow
The 1606-XLP100E accepts wide-range AC mains input (L, N, PE terminals) and converts via an isolated switch-mode topology to a regulated 24VDC bus. The DC output (+V, –V, PE) feeds the control panel 24VDC rail, supplying PLCs, I/O modules, sensors, and actuators. The DC OK relay contact (if wired) provides a dry-contact signal to the PLC input card for power health monitoring. Output voltage is adjustable via front-panel trim potentiometer. For redundant architectures, two 1606-XLP100E units feed a common bus through Schottky diode ORing modules (e.g., 1606-XLRED4), ensuring seamless failover with zero output interruption.

Technical FAQ
Q: Can the 1606-XLP100E power a ControlLogix chassis directly?
A: The 1606-XLP100E supplies the 24VDC I/O and field device rail. The ControlLogix chassis power supply (e.g., 1756-PA75) is a separate unit. The 1606-XLP100E is ideal for powering the 24VDC I/O bus, sensors, and distributed devices associated with the chassis.
Q: Is parallel operation supported for redundancy?
A: Yes. Two 1606-XLP100E units can be paralleled using Rockwell’s 1606-XLRED4 diode ORing module to create a redundant 24VDC supply. This is the recommended architecture for high-availability applications.
Q: What is the derating curve above 60°C?
A: Above 60°C ambient, output power must be derated linearly to 50% at 70°C. Ensure adequate panel ventilation for installations in high-ambient environments.
Q: Is this unit suitable for Class I Division 2 hazardous locations?
A: Yes. The 1606-XLP100E carries ATEX Zone 2 and Class I Division 2 certification, making it suitable for use in panels installed in light hazardous areas without additional explosion-proof enclosures.
Q: What is the difference between 1606-XLP100E and 1606-XLP100B?
A: The suffix denotes the input voltage range variant. The ‘E’ suffix indicates the universal input (85–264VAC) version suitable for global deployment. The ‘B’ suffix is the 120VAC-optimized North American variant. For international projects, always specify the ‘E’ variant.
