The ABB SDCS-FEX-2A is an integrated single-phase field exciter and power supply circuit board engineered for internal mounting within armature converter modules. Functioning as a digital field exciter board, this module consists of an integrated power part and an onboard control processor section that links all internal components both electrically and mechanically.
The SDCS-FEX-2A is designed explicitly for installation inside ABB DCS converter modules of type C1, C2, and C3 alongside the electronic power supply board SDCS-POW-1, but is completely incompatible with C4 frame sizes. Operating with a wide single-phase rated input voltage range from 110V to 500V AC and a maximum current capacity of 16A, the 3ADT311500R1 uses a fully digital micro-controller layout to dynamically scale its active burden resistors, ensuring optimal signal resolution across an automated selection band between 3A and 16A.

The SDCS-FEX-2A module is specifically engineered for frame integration into DCS type C1, C2, and C3 converter modules. Do not attempt mechanical or electrical structural mounting inside larger type C4 converter bays, as the ventilation flows, structural sizing, and communication path cabling are completely non-interchangeable. The module retains a permanent fixed RS485 network routing identifier at Node Address 1, which requires strict configuration adherence on the accompanying master SDCS-CON-x board layout.
During initialization, the onboard microcontroller depends on real-time parameter streaming from the main armature processor memory via flat cable X14. If an interruption occurs in the RS485 communication link or parameter table configuration values fail to deploy correctly, the field control software will fail to scale the internal burden resistors, causing zero-current tracking faults. Additionally, when testing output loop values via the terminal row X20:, external multi-meters must maintain an internal operational resistance greater than 1M Ohm to prevent short-circuit conditions or measuring errors.
CRITICAL WARNING: LETHAL HIGH VOLTAGE AC/DC POTENTIALS
Isolate, switch off, and safety lockout all incoming three-phase AC feeder lines and distinct single-phase excitation voltage links supplying the converter chassis. Internal storage capacitors preserve high-energy electrical charges after supply line termination. Allow a minimum of 15 minutes for safety bleed-down to discharge completely, and verify a zero-energy state across all terminals with a calibrated testing device before handling internal circuitry.
