Features:

  • Power Distribution Hub for DCS800 Converter Low-Voltage Circuits
  • Integrates Armature Bridge Control with Built-In Excitation Management
  • Adapts to 115 VAC or 230 VAC Auxiliary Input with Jumper-Selectable Relay Logic
The SDCS-PIN-4 serves as the dedicated power interface board within ABB DCS800 DC converter modules rated D1 through D4+ (20 A to 1190 A). It accepts auxiliary voltage inputs of 115 VAC or 230 VAC and automatically adapts to the incoming supply, distributing all low-voltage power required by the drive and its connected expansion options. The SDCS-PIN-4 also incorporates high-impedance measurement circuits for both DC and AC voltages within the armature bridge, and it provides current-transformer interfaces for armature-current sensing. For D1 to D4 frame sizes, the SDCS-PIN-4 additionally manages the on-board exciter and controls excitation current, with drive firmware automatically configuring current and voltage measurements, load-resistance settings, and 2-Q/4-Q operating modes.

The SDCS-PIN-4 is a critical element in the DCS800 power path, directly influencing proper operation of the overall drive system. It mounts inside the module and bonds to chassis ground through its grounding terminal. The board supports main supply voltages ranging from 230 V up to 525 V, as well as 600 V configurations, and its compact design maintains a minimal footprint within the converter assembly.

For applications where the auxiliary supply is a stable 230 VAC or 115 VAC source, the SDCS-PIN-4 can be configured via jumper S1 in the 1-2 position to enable relay K301. In environments with fluctuating 230 VAC auxiliary power—such as diesel-generator networks—jumper S1 must be set to 2-3 to lock the SDCS-PIN-4 into fixed 230 VAC mode and ensure stable operation. This selectable logic allows the SDCS-PIN-4 to accommodate varying site conditions without hardware replacement. A related variant, the SDCS-PIN-4b, also supports 115/230 VAC auto-recognition but does not implement the S1 jumper relay-switching function, making the two boards complementary choices for different installation requirements.

The SDCS-PIN-4 ABB Interface board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The ABB SDCS-PIN-4 Interface Board is a critical component tailored for ABB DCS800 converter modules (sizes D1 to D4+, 20 A–1190 A), serving as a central hub for power distribution and drive control.  It operates on 115 VAC auxiliary voltage with a tolerance of -15%/+10% and supports a frequency range of 45 Hz to 65 Hz, ensuring compatibility with diverse industrial power grids.  With 120 VA power consumption and power loss below 60 W, it balances efficiency and reliability for continuous operation.

Equipped with 20 A/20 ms inrush current, 30 ms minimum mains buffering, and a powerfail trigger at <185 VAC, the board maintains stability during voltage fluctuations and disruptions.  Its core functions include powering all low-voltage components of the drive and connected options, controlling the armature bridge (with high-ohmic DC/AC voltage measurement and current transformer integration for armature current), and managing the OnBoard field exciter plus field current measurement (for D1–D4 modules).

Designed for mains supply voltages from 230 V up to 525 V/600 V, the SDCS-PIN-4 features internal ground connections and leverages DCS800 firmware parameters for automatic adjustment of current/voltage measurement, burden resistor settings, and 2-Q/4-Q operation—seamlessly integrating into drive systems to enable precise control and monitoring.
