About the DS200LDCCH1AFA
The DS200LDCCH1AFA is a drive control local area network (LAN) communications board developed by General Electric. It is a component of the Mark V Turbine Control System drive board series. These cards interface well with GE’s DIRECTO-MATIC 2000 exciters and drives.
The board provides functions to the host drive, including I/O, device, and motor control functions. The Mark V Series has applications in the management and control systems of steam, gas, and wind turbine automated drive assemblies.
The Mark V Series is notable as one of the final GE Mark product series to use the patented Speedtronic control system technology, first seen with the Mark I Series in the late 1960s.
The DS200LDCCH1AFA is not the original product for its intended Mark V Series functional role; that would be the DS200LDCCH1 parent LAN Communications Board, which lacks the DS200LDCCH1AFA's three significant product revisions.
Hardware Tips and Specifications
The DS200LDCCH1AFA is accurately described as a printed circuit card (LAN Communications Card) due to its small stature.
Onboard software is stored in six flash PROM modules (for configuration data) and an EEPROM component (for field-adjustable parameters).
It houses four microprocessors:
- Drive Control Processor (DCP): Performs digital and analog I/O conversions and controls peripheral I/O devices.
- LAN Control Processor (LCP): Accepts five different bus LAN systems.
- Motor Control Processor (MCP): Processes digital I/O communications.
- Co-Motor Processor (CMP): Provides additional processing speed for complex calculations.
A GE programmer keyboard is included on the board for direct user access to system diagnostics and error codes.
This DS200LDCCH1AFA is compatible with up to five different bus systems:
- DLAN+: GE’s ARCNET®-based drive LAN protocol.
- DLAN: GE’s drive LAN for smaller and earlier larger drives.
- Genius® bus: Via an interface board (e.g., DS200ADGI).
- CPL (Control Party Line) serial link: Via an interface board (e.g., DS200ADCI).
- C-bus: A parallel differential bus, via an interface board (e.g., DS200ADCI).
Shipping, Installation, and Support
Any part shipped by AX Control will be protected by a standard static cling plastic wrapping.
Before removing the board, review all installation parameters provided by the manufacturer. Wiring instructions are available in the series manual and device datasheet.
General Electric originally provided technical support for all Mark V series members.
AX Control's trained sales staff is available via phone or email for pricing information for the DS200LDCCH1AFA or other parts/repairs.
