Honeywell 10303/1/1 FSC Power Supply Distribution Module

The Honeywell 10303/1/1 is a Power Supply Distribution (PSD) Module designed for use in systems featuring redundant Central Parts and non-redundant I/O configurations. Its primary function is to consolidate the output from redundant Power Supply Units (PSUs) into a single 5 VDC supply for the non-redundant I/O section of the system. This ensures consistent and reliable power distribution across the system components.

The module is engineered to maintain voltage stability within strict limits (±5%), which is crucial for the proper functioning of sensitive electronic components. To achieve this, the PSD modules should be positioned adjacent to the PSU modules to minimize voltage drops in the wiring. The recommended minimum wire diameter is 2.5 mm² (AWG 14).

Note: The PSD module should only be replaced when the power supply to its PSU is switched off to prevent potential damage or safety hazards.
