Description

The Honeywell 10303/1/1 is a specialized power supply distribution module engineered for the Honeywell FSC (Fail Safe Controller) safety system. This module serves as a critical interface for power management, specifically designed for configurations utilizing redundant central processing units alongside non-redundant I/O sections. Its primary function is to combine outputs from multiple power supply units (PSUs) to provide a regulated 5 VDC supply, ensuring stable voltage distribution and system reliability in demanding safety-critical environments such as oil and gas processing, chemical plants, and power generation facilities.

Features

Passive distribution design: Operates without internal power consumption, minimizing heat generation and failure points.
Redundancy support: Merges redundant PSU outputs to maintain consistent power delivery.
High current capacity: Supports a total module load of up to 20 A.
Voltage stability: Designed to maintain a strict voltage tolerance of +/- 5 percent.
Robust connectivity: Utilizes a DIN 41612 H15 connector with Faston terminals for secure, high-current power transmission.
Integrated protection: Features reverse voltage protection up to 30 V.

Applications

This module is intended for use in Honeywell FSC safety systems where reliable power distribution to I/O racks is required. It is commonly deployed in industrial automation systems where maintaining uptime and preventing power-related faults is essential for process safety.

Installation Guidelines

Power-down procedure: Always switch off all associated PSU power before inserting or removing the module to prevent system disturbance or electrical arcing.
Proximity: To maintain the required +/- 5 percent voltage tolerance, install the module as close to the PSU units as possible.
Connector handling: Ensure the DIN 41612 H15 connector is fully seated and that Faston terminals are securely crimped and tightened to prevent high-resistance connections.
Environment: Ensure the installation location is within the specified operating temperature range (0 to 60 deg C) and free from excessive vibration or corrosive contaminants.
Grounding: Follow standard industrial grounding practices for the FSC system backplane to ensure signal integrity and safety.

FAQ

What is the primary function of the 10303/1/1?

The module acts as a passive distribution interface that combines redundant power supply outputs into a single 5 VDC supply for non-redundant I/O sections within a Honeywell FSC system.

Does this module require external power?

No, the 10303/1/1 is a passive device and does not consume power for its own operation; it merely routes and balances the power supplied by the PSUs.

What is the maximum current rating?

The module is rated for a total load of 20 A, with individual pins on the DIN 41612 H15 connector rated for a maximum of 10 A each.
