Features:
- Pairs the K4LCN-4 board designation with Honeywell part 51402755-100.
- Provides the processor and Local Control Network foundation in History Module hardware.
- Works with a separate generation-matched mezzanine memory board.
The combined K4LCN-4 and 51402755-100 identity defines the later K4LCN processor board execution.
It provides the LCN processing interface for the supported History Module hardware.
Match the mezzanine memory, node address, chassis revision and complete board labels before service.
Legacy K4LCN supply is verified against processor, memory and History Module configuration.
