Description

The ABB SDCS-UCM-1C is a Unified Control and Memory Module for the ABB DCS400 DC drive platform, consolidating parameter storage and control execution functions on a single board. The SDCS-UCM-1C serves as the intelligence layer within ABB's SDCS (DC Drive Control System) architecture, handling critical control functions for DC motor speed regulation in heavy industrial applications.

The SDCS-UCM-1C features an External DC Voltage Measurement Kit configuration with two resistor chains for voltage reduction. These resistor chains of the SDCS-UCM-1C enable external mounting outside the drive module, providing safe and accurate DC voltage measurement without interfering with the main drive circuitry. The SDCS-UCM-1C provides dual DC voltage terminal connections via X1 and X2 terminals, facilitating flexible wiring configurations for various voltage monitoring applications.

The SDCS-UCM-1C connects directly with analog input channels (such as AI3) on standard drive control boards, enabling real-time EMF (electromotive force) and armature voltage scaling. This direct connection capability of the SDCS-UCM-1C ensures precise feedback signal acquisition for optimal motor speed control and protection.

Features:

  • Two Resistor Chains for Voltage Reduction
  • External Mounting Outside Drive Module
  • Dual DC Voltage Terminal Connections (X1 and X2)
The SDCS-UCM-1 3ADT220090R0008 specifically for ABB DCS880 thyristor power converters in frame sizes H1 through H5. In these drive sizes, the DC voltage measurement is integrated on the SDCS-PIN-H01 board, making it impossible to split the DC voltage measurement and measure externally directly at the motor. This limitation causes problems when using a DC-breaker or US-style DC-contactor, because an exact DC voltage measurement cannot be obtained when the DC-breaker or contactor is open.

The SDCS-UCM-1C 3ADT220090R0008 ABB MEASUREMENT BOARD may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

With the help of the DC measurement set SDCS-UCM-1 for H1...H5, external DC voltage measurement at the motor terminals becomes possible. The board contains two resistor chains which are connected to the DC voltage (armature circuit) of the motor. The voltage reduced by the resistor chain is connected to analog input AI3 (XAI: AI3) of the DCS880. The DC voltage is wired to connectors X1 and X2, where the positive DC voltage (C1) is connected to connector X1 and the negative DC voltage (D1) to connector X2. The connection of X1 and X2 is done according to the nominal motor voltage.
