Basic Information

• Part Number: 51305072800 (51305072‑800)

• Module Type: Redundant LCN I/O Paddle Board (Enhanced)

• Compatible System: Honeywell TDC3000 / TPS

• Manufacturer: Honeywell

• Country of Origin: USA

• Weight: Approx. 0.18 kg (0.40 lb)

• Certification: CE, UL, CSA

• Status: Discontinued (new/remanufactured available)

Technical Specifications

• Network Interface: Dual CLCN‑A + CLCN‑B (redundant, enhanced signal integrity)

• Node Address: Configurable via rotary switches (more reliable than slide/jumper)

• Power Supply: 5 VDC from chassis backplane

• Operating Temperature: ‑10°C to +60°C (extended range)

• Storage Temperature: ‑25°C to +75°C

• Humidity: 5%–95% RH, non‑condensing

• Mounting: Dedicated slot in 5/10‑slot I/O chassis

Key Features

1. Enhanced Redundant LCN Ports: Improved transceiver design for longer cable runs and better noise immunity.

2. Rotary‑Switch Addressing: Precision 8‑position rotary switches for fast, accurate, and vibration‑resistant node ID setup.

3. Chassis Bus Bridging: High‑speed data transfer between I/O modules and redundant LCN network.

4. Extended Temperature Rating: Suitable for harsher industrial environments.

5. Advanced Diagnostics: LED status indicators for power, link, and fault; supports TDC3000 system diagnostics.

Application Scope

• Industries: Power generation, petrochemical, oil & gas, pulp & paper, metallurgy (critical processes).

• System Role: Primary redundant LCN communication interface for TDC3000/TPS I/O chassis.

• Use Case: Installed in 5/10‑slot chassis where high‑reliability redundant LCN is required (A/B active‑standby).

Installation & Wiring

1. Power Off: De‑energize chassis before insertion/removal.

2. Chassis Installation: Insert into dedicated slot and secure with screws.

3. CLCN Connections: Connect LCN‑A cable to Port A, LCN‑B cable to Port B (use shielded cables).

4. Address Setting: Use rotary switches to set unique LCN node ID (0–255).

5. ESD Protection: Wear anti‑static wristbands and use ESD‑safe work surfaces.

Maintenance Requirements

• Periodic Inspection: Check A/B cable connections, rotary switch settings, and LED status.

• Cleaning: Wipe dust with dry soft cloth; avoid liquid cleaners.

• Replacement: Use original/authorized Honeywell parts; do not disassemble.

• Fault Handling: Verify A/B cables, switch settings, and system diagnostics if communication fails.

Safety Notice

• All wiring/maintenance must be performed with power disconnected.

• Do not exceed rated temperature/humidity limits.

• Unauthorized modification/disassembly is prohibited.

• Comply with site safety rules and ESD procedures.
