About the DS200LDCCH1AHA
The DS200LDCCH1AHA is a drive control and LAN (local area network) communications board manufactured by General Electric. This board is a component of the Mark V Turbine Control System series, suitable for installation in DIRECTO-MATIC 2000 exciters and drives.
The Mark V Series has applications in managing and controlling wind, steam, and gas turbine automated drive assemblies. It's highly regarded in the industrial marketplace as one of the final GE Mark series to use their patented Speedtronic control system technology.
The DS200LDCCH1AHA is not the original product for this functionality; the DS200LDCCH1 parent board preceded it, lacking the DS200LDCCH1AHA's three significant product revisions.
Hardware Tips and Specifications
The card provides various I/O control and drive function services to the host drive.
It houses four microprocessors:
- LAN Control Processor (LCP): Accepts five different bus systems.
- Drive Control Processor (DCP): Converts analog and digital I/O signals, and converts incoming I/O from peripheral devices (encoders, timers).
- Motor Control Processor (MCP): Processes digital I/O signals.
- Co-Motor Processor (CMP): Provides additional processing power for strenuous calculations.
An alphanumeric programming keypad is attached for easy access to board diagnostics and error codes.
Reset options for the board include:
- A pushable RESET pushbutton.
- Acceptance of a +5-24 V DC voltage via the 30-pin 6PL connector.
- Programmed software controls.
- Automatic internal hardware watchdog protection.
- Soft resets can be performed through programming alteration or using a Mark V Series Programmer Module's reset key.
A stab connection is available for common reference to LAN interface boards, providing stiffening in high-noise environments.
Onboard testpoints are available for functional fault diagnosis before performing hard resets.
Software selections include six flash PROM Modules for configuration data and an EEPROM Module for field-adjustable parameters. Parameters are downloaded using drive configuration tools, likely the Mark V Series-standardized I/O Configuration editor.
Shipping, Installation, and Support
All boards from AX Control arrive in protective static-reducing plastic wrapping.
Before installation, users should review all manufacturer-provided installation parameters. A complete wiring guide is available in the series manual and the board’s datasheet.
General Electric originally provided technical support for all Mark V series members.
AX Control's sales staff is available by phone or email to provide pricing and other information for the DS200LDCCH1AHA or any other parts/repairs.
