Honeywell 51403519-160
- Product Name: K4LCN-16 TDC 3000 LCN Memory Processor Module
- Product Introduction: A core LCN (Local Control Network) memory processor module for the classic Honeywell TDC3000 DCS system. It undertakes system logic operation, process data caching, LCN network scheduling, and configuration storage. It is an enhanced upgrade of traditional LCN modules, featuring ECC memory error correction and power-off data protection.
Detailed content
- Technical Specifications:
- Model: 51403519-160 / K4LCN-16
- Type: TDC3000 LCN Memory Processor Module
- Core Processor: Motorola 68040 industrial dedicated CPU
- Memory: 16 MW high-speed industrial memory with ECC error correction
- Storage: RAM, ROM, EEPROM multi-layer architecture
- Bus Protocol: TDC3000 proprietary LCN
- Extended Protocol: Compatible with HART
- Signal Support: 0–5 V, 1–5 V, 0.4–2 V, 4–20 mA
- Channel Config: 12 single-ended + 4 differential
- Power: 24 VDC via TDC3000 rack backplane
- Protection: Over-voltage, over-current, ESD, surge; electrical isolation between core and ports
- Operating Temperature: -20 °C to +60 °C
- Storage Temperature: -40 °C to +85 °C
- Humidity: 5 %–95 % RH non-condensing
- EMC: Industrial-grade anti-interference
- Protection: IP20 (indoor cabinet)
- Functional Features: ECC hardware-level error correction ensures accurate operation. Comprehensive power-on self-test of processor, memory, bus, and storage. Precise fault diagnosis identifies memory errors, bus disconnection, and configuration loss. LED indicators show run, communication, and fault status. Hot-swap support allows online replacement. Power-off cache protection for key configuration.
- Application Scenarios: Chemical, power, oil & gas industries for aging TDC3000 DCS system replacement, hardware upgrades, and stability optimization.
- Structural & Material Characteristics: Reinforced PCB design for vibration resistance. Industrial component grade. Dimensions listed vary by source (approx. 175 × 150 × 50 mm per one supplier; another lists 85 × 65 × 30 mm); confirm exact mechanical drawing against your chassis before ordering.
- Working Principle: The Motorola 68040 CPU executes complex process operations and interlock logic, caches process data in ECC-protected memory, and schedules communication over the LCN proprietary bus with other TDC3000 nodes.
- Installation Requirements: Install in a TDC3000 rack chassis slot. Ensure backplane power matches 24 VDC specification. Maintain ambient temperature within -20 °C to +60 °C. Mount in IP20 or higher control cabinet.
- Usage Notes: Verify firmware revision compatibility with existing TDC3000 system. Use ESD protection during hot-swap. Monitor LED status for run/communication/fault. Perform configuration backup before replacement.
