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.
