Key Features

1. Precise Contactor Control & Drive
   • Delivers a 105 V DC, 250 ms pulse to reliably close 30–40 V DC contactor coils.
   • Regulates holding current via RV1 potentiometer to maintain stable contactor closure under varying loads.
   • Drives one high-speed contactor per board, supporting coordinated multi-contactor operation via jumper JP2.
2. Integrated Protection & Diagnostics
   • Onboard 4 A slow-blow fuse safeguards input power from overcurrent damage.
   • Three dedicated test points enable direct electrical testing and troubleshooting by technicians.
   • Single LED indicator provides real-time visual status of contactor close command and board operation.
3. Robust Industrial Compatibility
   • Designed for seamless integration with GE Mark V and DC2000 drive systems, fitting standard EX2100 and Innovation series cabinets.
   • Accepts wide-range 75–140 V AC/DC input power for flexible industrial power sourcing.
   • Ruggedized components and wide temperature tolerance ensure reliability in harsh plant environments.
4. Coordinated Multi-Bridge Operation
   • Jumper JP2 enables synchronization with other CDBA boards in multi-bridge drive systems, ensuring simultaneous contactor operation.
   • Optimized for fast dropout protection, critical for preventing motor damage during drive faults.
