Honeywell 10303/1/1 Power supply distribution module (PSD)

Honeywell 10303/1/1 Power Supply Distribution Module (PSD)

The 10303/1/1 Power Supply Distribution Module (PSD) is designed for use in systems with redundant Central Parts and non-redundant I/O. Its primary function is to combine the output of the power supply units (PSUs) in the redundant Central Parts into a single 5 Vdc supply for the non-redundant I/O part of the system. This ensures consistent power distribution and voltage regulation throughout the system.

Key Features:

• Redundant to Non-redundant Power Conversion: Combines outputs from redundant PSUs into one 5 Vdc supply for non-redundant I/O.
• Voltage Drop Management: Routes power through the module to create an equal voltage drop between the Central Part and I/O section.
• Proximity Installation: Requires installation next to PSU modules to minimize voltage drop due to wiring resistance.
• Easy Maintenance: PSD modules can only be exchanged with the PSU power switched off, ensuring safety and system integrity.

Notes

• PSD modules without a suffix code have a maximum current of 12 A.
• Ensure PSD modules are installed next to PSU modules to reduce voltage drop in wiring.
• Use a minimum wire diameter of 2.5 mm² (AWG 14) for connections.

This module is essential for maintaining stable and consistent power distribution in systems where redundant and non-redundant power configurations coexist. It ensures the non-redundant I/O parts receive reliable power supply without significant voltage drops, enhancing the overall system reliability and performance.
