Key interfaces:
X12/X13: Connects to power interface board for voltage, current, and temperature feedback
DDCS Channel: 4 Mbits/s fiber optic for fieldbus adapters
RS-485: For CDP control panel connection and serial communication
The SDCS-CON-2B is deployed across industries requiring robust, high-precision DC motor control :
| Industry | Application |
|---|---|
| Steel & Metals | Rolling mill main drives, coilers, uncoilers |
| Pulp & Paper | Paper machine section drives, winders |
| Mining | Hoist control, conveyor drives, mine winders |
| Plastics & Rubber | Extruder drives, internal mixers |
| Material Handling | Cranes, lifts, and winch systems |
Compatibility: SDCS-CON-2B is compatible with DCS500B and DCS600 drives only. It is NOT interchangeable with SDCS-CON-4 (used in DCS800 series) due to different hardware architecture and firmware .
Hardware Revision: The -2B version features improved EMC immunity compared to -2A. When replacing, verify the suffix matches your drive specification .
Commissioning: After replacement, drive parameters must be re-downloaded to the new board. If the original memory card is transferred, parameters can be retained .
