Product Description

Model Definition

• 51305072-200: Honeywell part number for CLCN‑A (A‑network).

• 5130: Honeywell DCS hardware series.

• 5072: CLCN series circuit design code.

• 200: Designates LCN A‑network variant (distinct from 300/400/800).

• Alias: CLCN‑A paddle board, LCN A‑network communication board, TDC3000 controller network card.

Technical Specifications

• System Compatibility: Honeywell TDC 3000, TPS, Experion PKS (C300).

• Power Supply: 24 VDC from controller backplane.

• Operating Temperature: -40 °C to +70 °C.

• Storage Temperature: -40 °C to +85 °C.

• Humidity: 5%–95% non‑condensing.

• Dimensions: Approx. 180 mm × 70 mm × 40 mm.

• Weight: Approx. 0.2 kg.

• Data Rate: 1 Mbps.

• Max Nodes: 255 per network segment.

• Certifications: CE, UL, CSA, RoHS.

Interface and Communication Configuration

• LCN‑A Port: BNC coaxial connector for LCN A‑backbone.

• Controller Interface: Gold‑finger edge connector for dedicated CB120/CB121 slot.

• Isolation: Full electrical isolation between controller and LCN to suppress common‑mode noise.

• Indicators: Power, Link, Fault LEDs for real‑time status.

• Protocol: Honeywell proprietary LCN; supports remote diagnostics via engineer station.

Core Functions

1. A‑Network Connectivity: Dedicated LCN A‑network access for controllers in redundant pairs.

2. Signal Adaptation: Converts between controller single‑ended and LCN differential signaling.

3. Electrical Isolation: Contains faults to prevent network‑wide propagation.

4. Impedance Matching: Optimizes coaxial transmission, reduces reflection/attenuation.

5. Redundancy Support: Pairs with CLCN‑B for dual‑network failover and high availability.

Application Scenarios

• Controller Redundancy: TDC3000/TPS with CB120/CB121 and dual LCN A/B networks.

• Process Industries: Oil/gas, chemical, power, petrochemical, pharmaceutical plants.

• Control Rooms: Standard industrial temp/humidity in control cabinets.

• System Upgrades: Replacement for older KLCN‑A boards; fits existing LCN infrastructure.

Usage and Maintenance Instructions

Usage

1. Installation: Insert firmly into controller’s CLCN‑A slot; tighten screws to resist vibration.

2. Wiring: Connect LCN A coaxial cable to BNC; ensure clean, tight connection.

3. Power‑on: Energize controller; verify steady Power/Link LEDs, no Fault.

4. Configuration: Set LCN A address and redundancy via DCS engineer station.

Maintenance

• Environment: Keep clean, dry, ventilated; maintain rated temp/humidity.

• Inspection: Check LEDs monthly; inspect BNC tightness/cleanliness quarterly.

• Cleaning: Wipe dust with dry soft cloth; no liquid cleaners.

• Storage: Store spares in anti‑static packaging, cool/dry, away from ESD/magnetic fields.

• Service: Do not disassemble; all work by qualified personnel.
