The DS200LDCCH1AGA is a GE Mark V LDCC board. Its central job is broader than simple communications: the board combines drive control, motor control, I/O processing, and LAN communication functions. GE’s LDCC documentation identifies the LCP, DCP, MCP, and CMP as the four major processing functions on this board family.
Product Introduction
The GE DS200LDCCH1AGA is a Drive Control/LAN Communications Board used in GE Mark V drive systems, particularly DIRECTO-MATIC 2000 drives and exciters. The board integrates several processing functions on one PCB: the DCP handles drive-related analog and digital I/O processing, the MCP handles motor control and digital I/O functions, the CMP provides additional computational capacity, and the LCP manages LAN communications.
From a maintenance perspective, the DS200LDCCH1AGA should be treated as a system-specific Mark V control board, not as a generic communication card. Its firmware/configuration storage, processor arrangement, jumper settings, and LAN interface are all relevant to successful replacement. GE’s applicable manual is GEI-100216, which should be used alongside the actual drive documentation when commissioning or troubleshooting the board.

Application Scenarios & Field Pitfalls
Engineering Pain Point
The biggest replacement risk is assuming that every DS200LDCC board is interchangeable. The LDCC family contains multiple hardware and functional revisions. The DS200LDCCH1AGA is specifically an H1AGA configuration, while closely related models such as DS200LDCCG1AGA have different functional/artwork revision combinations. The revision information is part of the hardware identity and should not be ignored.
Typical Applications
- GE DIRECTO-MATIC 2000 drives — drive control, I/O processing, diagnostics, and communications.
- Exciter systems — processing control and feedback functions associated with GE excitation equipment.
- Legacy industrial drive systems — maintaining Mark V installations where the original control architecture remains in service.
- Drive troubleshooting and refurbishment — replacement of failed LDCC assemblies while retaining the existing Mark V configuration.
Technical Pitfalls to Avoid
- Do not classify it as a pure LAN card. The LCP is only one of four major processing functions. The DCP, MCP, and CMP also perform drive, motor, I/O, and computational tasks.
- Verify the exact H1AGA suffix and board revision. DS200LDCC variants can look similar while carrying different functional/artwork revisions.
- Preserve configuration information. The LDCC assembly uses onboard flash PROMs and an EEPROM for configuration-related data. A replacement board may require configuration or firmware information from the original system.
- Record jumper positions before removal. The LDCC board uses configurable jumpers, and the installed settings should be documented before swapping the PCB.
- Do not rely on generic Ethernet/RS-485 descriptions. Some secondary listings describe this board as a conventional Ethernet/RS-485 communications card. The stronger LDCC documentation instead identifies the LCP as supporting Mark V-specific bus systems including DLAN+, DLAN, Genius, CPL, and C-bus.
Related Products
- DS200LDCCH1A — earlier LDCC-H1 family board; verify revision and configuration before considering substitution.
- DS200LDCCH1AFA — related H1 LDCC configuration with a different artwork/revision suffix.
- DS200LDCCH1AHA — another H1 LDCC variant; exact hardware revision must be matched.
- DS200LDCCH1AKA — related LDCC drive/LAN control board with a different revision configuration.
- DS200LDCCH1ALA — another H1 LDCC variant used in legacy GE drive systems.
- DS200LDCCG1AGA — LDCC board with G1AGA revision designation; similar core architecture but not an automatic substitute for H1AGA.
- DS200LDCCG1A — earlier G1 LDCC family board.
- DS200KLDCF1A — Mark V software PROM set associated with LDCC-family applications; relevant when investigating firmware/configuration rather than replacing the control board itself.
- DS200KLDCG1A — Mark V LED/key display board associated with the broader LDCC/operator-interface architecture.
Procurement Check
For GE DS200LDCCH1AGA, I would put the complete designation on the purchase requirement rather than shortening it to “DS200 LDCC.” The critical identification is:
→ Mark V → LDCC → H1AGA revision → GEI-100216
Also retain the original PROM/configuration information and jumper positions when removing an installed board. This is one of those legacy GE boards where an apparently correct base model can still fail the replacement test if the revision or configuration does not match the drive.
