ABB SDCS-BAB-F01 3ADT316400R0501 Field Exciter Interface Board

Products Description

ABB SDCS-BAB-F01 3ADT316400R0501 Field Exciter Interface Board

OnBoard Three‑Phase Half‑Controlled Field Exciter for DCS Drive Systems

Key Features & Benefits

• Integrated Three‑Phase Field Exciter: Functions as an OnBoard half‑controlled field exciter for DC motors, eliminating the need for external excitation equipment in supported drive sizes 

• Direct Armature Supply: The field exciter is powered directly from the armature mains, simplifying system architecture and reducing external wiring requirements 

• Precise Excitation Current Control: Handles output currents up to 30 A (dependent on module size), with current scaling automatically selected using the motor's nominal excitation current 

• Flexible Compatibility: Supports multiple ABB drive platforms including DCS500, DCS550, DCS600, and DCS800 series, providing a versatile spare part for varied installed bases 

• Integrated Overcurrent Protection: Uses fuses F100–F102 (KTK 25A) on the associated SDCS‑PIN‑H01 board for reliable protection of field winding cables and motor windings 

• Snubber Circuit Integration: Shares snubber circuitry with the armature bridge for improved transient suppression and system reliability 

• Industrial‑Grade Construction: Built for reliable operation in harsh industrial environments with wide temperature tolerance and IP20 protection rating 

Technical Specifications

Module Size Compatibility

Note for DCS880 H3/H4: For 600V converter sizes H3 and H4, the OnBoard field exciter is not supplied as standard . For size H5 drives, this field circuit interface is not used .

System Architecture

The SDCS‑BAB‑F01 board is located between the power section and the control board, serving as the interface for field circuit control :

The board works in conjunction with:

• SDCS‑CON‑H01 (control board) or SDCS‑CON‑F (for DCS550) — provides synchronization via the L1, L2, L3 network 

• SDCS‑PIN‑H01 / SDCS‑PIN‑F — hosts firing pulse amplification and protection fuses 

Key Applications

The SDCS‑BAB‑F01 is deployed across heavy industries requiring robust DC motor excitation control:

Configuration Notes

• If the OnBoard field exciter is not required for a specific application, it can be disabled in the firmware 

• The current scaling is automatically selected using the motor's nominal excitation current 

• For field current ratings exceeding the OnBoard capacity, use the appropriate external field exciter option
