Product Short Description
Product Introduction
The GE DS200CDBAG1ABA is a single – channel contactor driver board (CDBA) engineered for GE Mark V Speedtronic and drive control systems, serving as the interface between drive control logic and high – speed contactors. It supplies controlled power to open and close contactors, enabling fast – acting dropout protection for drives. The board connects to power supply and control boards such as DS200DCFB, DS200SDCI, or DCVA, and can drive one high – speed contactor with a 30–40 VDC coil. It applies 105 VDC for 250 msec to force contactor closure, then regulates the holding current via potentiometer RV1. It features configurable jumpers, an LED status indicator, test points, and a fuse, and supports coordinated operation in multibridge systems through jumper JP2 (revisions G1BBA and later). Designed for industrial durability, it ensures reliable contactor control in turbine and heavy – duty drive applications, with a reference manual GEI – 100182B providing comprehensive setup guidance.

Functional Features
- High – Speed Contactor Control: Drives single high – speed contactors with 30–40 VDC coils, enabling fast dropout protection in drives for safe system shutdown.
- Pulsed Closure & Current Regulation: Delivers 105 VDC for 250 msec to force contactor closure, then maintains a regulated holding current via RV1 to optimize coil life and reduce power consumption.
- Coordinated Multibridge Operation: Jumper JP2 (revisions G1BBA +) synchronizes contactor operation across multiple CDBA boards in multibridge systems, ensuring all contactors act simultaneously.
- Status Monitoring: LED indicator shows local contactor close command status when coordinated operation is enabled, simplifying troubleshooting.
- Testability: Three test points allow on – board voltage signal verification, aiding in diagnostics and calibration.
- Plug – and – Play Integration: Interfaces seamlessly with DS200DCFB, DS200SDCI, or DCVA power/control boards without additional hardware modifications.
- Power Input Protection: Internal fuse FU1 safeguards the board from input power surges and overloads.
- Adjustable Holding Current: Potentiometer RV1 lets users set the exact holding current to match contactor coil specifications.
- Industrial Durability: Constructed with industrial – grade components to withstand extreme temperatures and harsh operating conditions.
- Compliance & Documentation: Complies with Mark V system standards, supported by detailed setup and operation guidelines in manual GEI – 100182B.
