Honeywell 51196655-100 Product Description

Model: 51196655100 (Standard Model: 51196655-100 / ACX633)

Brand: Honeywell

Series: TDC 3000 / TPS / UCN Distributed Control System

Type: Dual Node System Power Supply Module

Status: Discontinued 

I. Product Overview

51196655-100 (ACX633) is a highly reliable, dual-output, redundant system core power supply specifically designed for the NIM (Network Interface Module) of TDC 3000/TPS systems, UCN interfaces, and dual-node controllers. It provides pure, isolated, and uninterrupted power for system control nodes, communication interfaces, and global logic, and is a key component for ensuring the synchronization of the DCS network clock, smooth communication, and uninterrupted control.

It forms a three-level power architecture with 51196653 (HM power supply) and 51196654 (auxiliary power supply) of the TDC 3000 system.

III. Core Functions and Advantages

1. Dual-node redundancy, uninterrupted throughout the network

Dual-isolated output: Supplies power to both dual-node controllers simultaneously, single power failure does not affect the other node

1+1 redundancy enhancement: <8ms fault switching, zero interruption, zero data loss

Load Balancing: Intelligent load distribution of dual power supplies, lower temperature rise, longer lifespan

Wide voltage adaptive: 85~264V AC, stable operation under grid fluctuations

2. Low noise, strong isolation, zero communication errors

2500V strong isolation: Blocks ground potential difference, strong electromagnetic interference, zero communication errors, nodes do not drop out

<25mV ultra-low ripple: Pure DC, ensures stability of CPU, memory, and communication

Full metal shielding: Strong anti-EMI/RFI, stable in chemical plant / power plant strong interference environment

Clock Synchronization: Built-in line frequency clock, precise synchronization of the entire network clock 3. Industrial-grade high-reliability design

Hot-swappable: Replace the power supply online, system does not stop and control is not affected

Full protection mechanism: Overvoltage / Overcurrent / Short circuit / Overheating / Reverse connection hardware protection

Three-proof coating: PCB board dust-proof, moisture-proof, and corrosion-proof

Long-life components: Military-grade capacitors and semiconductors, 24/7 operation for 15 years +

Status visualization: Front panel LED + system diagnosis, real-time monitoring of voltage / current / temperature / faults

4. System-level seamless integration

Plug-and-play: Automatic identification and synchronization when inserted into the rack, no configuration required

Remote alarm: DCS system collects status in real time, faults report alarms actively

Downward compatibility: Perfectly replaces 51195068-xxx, no need to reroute lines, seamless upgrade

Low power consumption and efficiency: ≥ 90% efficiency, energy-saving, reducing the cooling load of the data center
