Physical Construction and Component Layout
This DS200LDCCH1A DS200LDCCH1AKA LAN communications board measures 8.2 inches in length. Its width reaches 6.4 inches with a thickness of 1.3 inches. The total weight comes to approximately 1.24 pounds. Manufacturers placed 312 discrete components on this six-layer PCB. These components include a 32-bit controller, memory chips, Ethernet PHY, and isolation transformers. Both DS200LDCCH1A and DS200LDCCH1AKA share the same communications architecture.
Network Interfaces and Protocol Support
DS200LDCCH1A DS200LDCCH1AKA provides two independent Ethernet ports for network redundancy. Each port supports 10/100Base-T with auto-sensing data rates. RJ-45 connectors include magnetic isolation for surge protection. The board supports Modbus TCP for industrial device communication. SRTP (Service Request Transport Protocol) handles GE-specific messaging. EGD (Ethernet Global Data) enables high-speed data exchange between controllers. An RS-232 port provides serial connectivity for legacy devices.
Processing Power and Memory Resources
DS200LDCCH1A DS200LDCCH1AKA features a 32-bit communication controller at 66 MHz. The board includes 4 MB of SDRAM for packet buffering. Flash memory provides 2 MB of storage for firmware and configurations. Eight LED indicators show network and system status clearly. Green LEDs indicate link activity and data transmission. Yellow LEDs signal collision or error conditions. Therefore, technicians can diagnose network issues without additional tools.
Energy Storage and Application Use
DS200LDCCH1A DS200LDCCH1AKA integrates eight 220µF capacitors for bulk energy storage. Six additional 47µF capacitors filter high-frequency power noise. The board draws 750 milliamps from the 5V DC backplane supply. You will find this board in GE Mark V and Mark VI turbine control systems. It connects turbine controllers to plant-wide Ethernet networks. The board operates reliably from 0°C to 55°C ambient temperature. For example, it links HMIs, DCS systems, and remote monitoring stations. Therefore, this LAN communications board enables modern industrial networking for legacy GE automation systems.
