Product Introduction

51304685-150 is the entry-level advanced communication module (AdvComm R150) of Honeywell Experion PKS/TDC3000/UCN system. It provides a basic high-speed data link between the controller and I/O, as well as between the upper computer and the controller. It is the basic communication card for the old DCS network, focusing on low-cost and low-power communication scenarios.

Model Interpretation

5130: Honeywell TDC3000/UCN/Experion PKS DCS series;

4685: Advanced Communication (AdvComm) card category;

150: Hardware version, representing the R150 streamlined, non-redundant, UCN single interface, basic protocol configuration (compared to 200 which is R200 basic type and 250 which is R300 redundant enhanced type). Technical Specifications

Communication interface: UCN bus (1Mbps), no Ethernet port;

Supported protocols: Only UCN dedicated protocol (no Modbus or other third-party protocols);

Redundancy capability: Does not support redundancy, operates with a single card;

Operating voltage: 24VDC ±10%, powered by the bus;

Power consumption: Approximately 20% lower than R200/R300, suitable for low-power cabinets;

Environmental conditions: Operating temperature 0℃～+55℃, storage -40℃～+70℃, humidity 5%–95% (no condensation);

Structural weight: Standard DCS card, approximately 0.45kg;

Certifications: CE/UL, basic three-proof coating.

Interface and communication configuration

System connection: UCN interface directly connects the controller and the local I/O subsystem;

Protocol conversion: No third-party protocol conversion capability, only native UCN communication;

Clock synchronization: Dependent on UCN network clock, no independent clock chip;

Diagnostic interface: Simple status indicator lights (only running / fault), basic online diagnosis;

Hot swapping: Supports hot replacement without affecting system operation. Core function

Basic UCN Communication: Ensures real-time data transmission between the controller and I/O;

Low power consumption operation: Suitable for scenarios with limited power supply capacity of the cabinet;

Easy maintenance: Compact structure, few fault points, compatible with the operation of old systems;

Data caching: Only caches core control data, without large-capacity storage. Applicable scenarios

Adaptation system: Honeywell TDC3000, UCN older system (compatible with Experion PKS but not recommended for new purchases);

Industry applications: Spare parts replacement for old DCS systems in process industries such as petrochemicals and power generation;

Typical uses: Small non-redundant system controller - I/O communication, replacement of old equipment spare parts, low-cost basic network setup.

Installation and maintenance Installation

Insert the standard slot of the DCS cabinet and lock the back panel connector;

Connect the UCN bus and confirm that the operation indicator light is normal;

Configure the basic UCN parameters in the software and download for effective operation. Maintenance

Keep the cabinet clean and dry, and regularly check the UCN wiring;

Monitor the communication status using the system's basic diagnostic tools;

Store spare parts in anti-static bags to prevent electrostatic damage;

Do not disassemble the machine privately; have repairs carried out by professional personnel.
