Model Explanation

51400668-100: Honeywell part number (without delimiter, i.e. 51400668100)

51400668 = HPM Main Control Card Series

100 = Standard version, Rev A/B hardware, industrial-grade temperature range

Component Type: HPM Controller Board (HPM Controller Board)

Adapter Rack: TDC 3000 HPM Standard 10-slot Rack (paired with 51400665-100 backplane) Technical Specifications

Processor: 16-bit industrial-grade CPU, with a main frequency of 8 MHz

Memory: RAM 128 KB, ROM 512 KB (fixed system firmware)

Control functions: Continuous PID, sequential logic, batch recipe, arithmetic operation, alarm management

I/O capacity: The single card supports up to 64 analog/digital I/O points

Network communication: LCN (5 Mbps), UCN (1 Mbps) dual network interfaces

Power supply: 5 VDC (power supply from the back panel, ±5%), power consumption ≤ 20 W

Operating temperature: 0°C ~ +60°C (environment of the cabinet)

Storage temperature: -40°C ~ +85°C

Humidity: 5% ~ 95% RH (no condensation)

Size: Standard 19-inch card (3U height)

Weight: 0.72 kg

Certifications: CE, UL, CSA, RoHS

Interfaces and Configuration

Backplane interface: Compatible with 51400665-100 power backplane, gold finger connection

Network interface: LCN coaxial BNC (75Ω), UCN twisted pair terminals

Status indicators: PWR (power), RUN (operation), LCN/UCN ACT (communication), FAULT (fault) LEDs

Redundant configuration: Supports dual-machine hot standby (1:1 redundancy), switching time < 30 ms

Installation method: Hot-swappable (supports no-down-time replacement)

Compatibility: Directly replaces the old HPM control card, compatible with the entire TDC 3000 HPM cabinet series Core function

Closed-loop process control: Implements multi-loop PID regulation (up to 32 loops), supports cascade, feedforward, ratio, and staged control, with a control accuracy of ±0.1%, ensuring stable process parameters.

Logic and batch control: Integrates ladder diagram logic and batch recipe management functions, enabling equipment interlocks, sequential start-stop, and automatic execution of batch production processes, suitable for intermittent production scenarios.

Real-time data processing: Collects on-site data from I/O modules, performs filtering, engineering quantity conversion, and alarm threshold judgment, and simultaneously uploads data to the LCN network, providing monitoring and historical archiving for the upper computer.

Dual network redundant communication: Connects to both LCN (system network) and UCN (control network), enabling bidirectional data interaction between the controller and the operation station, other controllers, and I/O modules, with automatic switching in case of a single network failure.

Fault self-diagnosis and redundant switching: Continuously monitors CPU, memory, and communication link status. In the event of a fault, triggers an alarm and automatically switches to the redundant card, with a non-disruptive switch, ensuring continuous production. Applicable scenarios

System: Honeywell TDC 3000, TPS, Experion PKS (compatible with C200/C300)

Cabinet: HPM control cabinet, integrated cabinet for I/O and control

Industry: Petrochemicals, thermal power, nuclear power, metallurgy, cement, glass, pharmaceuticals, papermaking

Application: Redundant configuration of main controllers, replacement of old system HPM components, expansion of process control loops, upgrade of batch production systems, renovation of core control layer of TDC 3000 system
