GE DS200SDCCG1A Drive Control Card

Configured for motor drive regulation, process feedback execution, and controller communication in GE Mark V and Directo-Matic 2000 systems, the GE DS200SDCCG1A (DS200SDCC Drive Control Card) provides direct electrical execution. The board processes drive feedback, executes motor control algorithms, manages onboard memory resources, and exchanges data through system communication interfaces. It incorporates multiple processors, removable EPROM storage, configurable hardware settings, and expansion capability for optional daughtercards.

Backplane Communication and Firmware Compatibility

The DS200SDCCG1A functions as the primary processing board within the drive control architecture and exchanges operational data with connected system modules through its onboard communication interfaces and optional daughtercards. The multi-processor design separates motor control execution, communication management, and signal processing into dedicated processing resources.

Four socketed EPROM locations allow installation of application-specific firmware and configuration data. When replacing EPROM devices or upgrading firmware, the installed firmware revision should remain compatible with the associated Mark V or Directo-Matic 2000 hardware configuration. Hardware jumpers and DIP switches should be configured to match the required operating mode before system commissioning.

Frequently Asked Questions

Q: Can the EPROM devices be replaced without replacing the complete board?
A: Yes. The board provides four socketed EPROM locations intended for user-serviceable firmware and configuration memory. Replacement firmware should match the system hardware revision and application requirements.

Q: Does the DS200SDCCG1A support communication expansion?
A: Yes. Dedicated board-to-board connectors support optional daughtercards used for communication interfaces or signal conditioning functions, depending on the system configuration.

Q: Is hot-swapping recommended for this board?
A: No. The available documentation does not specify hot-swap capability. Installation and removal should be performed only after the drive or control cabinet has been de-energized in accordance with applicable maintenance procedures.

Field Installation Guidelines

• Verify that the replacement board part number and functional revision match the installed system requirements before installation.
• Disconnect system power and confirm stored energy has been discharged before removing or installing the board.
• Observe electrostatic discharge protection when handling EPROM devices and processor components.
• Record jumper positions and DIP switch settings before board replacement to maintain the original hardware configuration.
• Ensure ribbon cable connectors are fully seated and installed in their designated connector locations.
• Route communication and signal cables separately from high-power motor conductors where practical to reduce electrical noise coupling.
• Verify protective grounding and cabinet shielding continuity before returning the system to service.
• After installation, confirm diagnostic LED status and verify communication with connected control modules during system startup.
