Honeywell 51109818100 Product Description

Model: 51109818100 (Standard Model: 51109818-100)

Brand: Honeywell

Series: TDC 3000 / TPS / Experion PKS Distributed Control System

Type: System Redundant Power Supply Module

I. Product Overview

51109818-100 is the core redundant power supply module of Honeywell's TDC 3000 control system, specifically designed to provide stable and uninterrupted DC power supply for Universal Station (US), GUS operation stations, AXM application modules, and HM historical modules. As the 1+1 redundant hot standby power supply for the system, it ensures seamless switching without interruption in case of a single power supply failure, and is the key driving force for ensuring the continuous operation and no power outage of the entire DCS control network, operation interface, and data storage unit.

Automatic load current sharing, dual power supplies evenly distribute the load, extending lifespan

Automatic fault diagnosis, the failed power supply exits immediately, without disturbance switching

Real-time monitoring of redundant status, supports remote alarm and status feedback

2. Ultra-wide voltage global compatibility

85-264VAC full voltage, compatible with global power grids

AC/DC dual input, meets special power supply requirements for power plants, petrochemicals, etc.

Compatible with all TDC 3000 operation stations and controllers

Direct replacement of old models such as 51109818-001/-002

3. Industrial-grade stable output

Ultra-low ripple, pure DC, protects precision circuits

Wide temperature stability, voltage does not drift under extreme conditions

Super isolation, blocks on-site surges and ground potential differences

Multiple protections, automatically shuts down in any abnormal situation, maintenance-free

4. Intelligent diagnosis and maintenance

LED status indication (PWR, OK, FAULT, REDUNDANT)

Hot-swappable design, online replacement does not affect system operation

Intelligent fan, low noise, long life, dustproof, moisture-proof

Remote monitoring, supports system software reading of voltage, current, temperature

IV. Typical Applications

TDC 3000 US / GUS operation station - redundant power supply

AXM application module, HM historical module, UWS engineer station - power supply

LCN network nodes, control processor, I/O rack - auxiliary power supply
