Honeywell 10300/1/1 FSC Diagnostic and Battery Module

Description

The Honeywell 10300/1/1 is a high-reliability DC/DC Converter Module designed specifically for Fail Safe Control (FSC) systems. This module serves as a critical power component, converting a standard 24 Vdc plant supply voltage into a regulated 5 Vdc output to power internal system modules. It provides essential galvanic isolation between the input and output voltages, ensuring system integrity and noise immunity in safety-critical environments. This unit is a pin-compatible, upgraded replacement for the legacy GK60 module.

Features

• Dual Voltage Conversion: Efficiently converts 24 Vdc to 5 Vdc.
• Galvanic Isolation: Separates supply voltages for enhanced safety and reduced EMI.
• Hot-Swappable: Designed for maintenance in active systems with strict safety protocols.
• Inrush Current Limiting: Integrated NTC resistor technology to manage startup current.
• Overvoltage Protection: Ensures stable 5 Vdc output to protect downstream components.

Applications

• Safety and Emergency Shutdown (ESD) systems.
• Burner and Boiler Management systems.
• Turbine and Compressor safeguarding.
• Process Control and DCS power distribution.
• Fire and Gas detection safety systems.

Installation Guidelines

• Cool-Down Period: Always keep the module offline for at least 30 seconds after removal or power-off. Failure to do so may prevent the NTC inrush limiter from cooling, leading to a supply voltage dip that could trip the system.
• Placement: Install the module as close as possible to the system bus (e.g., 12-SBUS). Due to tight 5 Vdc tolerance requirements, minimizing cable length is critical to reduce voltage drop.
• Wiring: Use properly sized cabling to ensure stable power delivery.
• Redundant Configurations: Note that in redundant setups with single I/O, the output LED may remain illuminated even if the specific module is powered off, as it may be back-fed by the redundant partner unit.
• Pin Configuration: For modules without a suffix code or with suffix code 04601, pin d14 (ON/OFF input) must remain disconnected.

FAQ

What is the 10300/1/1?

The Honeywell 10300/1/1 is a 24 Vdc to 5 Vdc DC/DC converter module used in Fail Safe Control (FSC) systems to provide regulated power to internal modules.

Why is the 30-second wait time important?

The module uses an NTC resistor to limit inrush current. If the module is re-powered before the NTC has cooled down, the resulting current spike can cause a voltage dip, potentially triggering a system trip.

Is this module compatible with older systems?

Yes, the 10300/1/1 is a pin-compatible, upgraded version of the older GK60 module.
