Overview
Enhance your ABB Low Voltage Drive system with the ABB SDCS-IOB-21 Standalone I/O Board (SKU: SDCS-IOB-21). This module directly replaces standard digital inputs and outputs, providing 8 externally mounted DI/O points. It operates with an input voltage level of 24 to 48V DC, ensuring compatibility with a range of DC power sources. The inputs are designed with filtering and galvanic isolation, offering robust protection and reliable signal integrity. Installation is straightforward, but note that terminals X6 & X7 on the main control unit must not be used when this SDCS-IOB-2x board is installed. For applications requiring both the IOB-21 and IOB-3 modules, the combination kit (SDCS-IOB-21/IOB-3) must be ordered separately. This board is an essential component for expanding the input/output capabilities of your ABB drive system, allowing for greater control and monitoring flexibility in industrial automation setups. Its design prioritizes signal clarity and system protection through its isolated and filtered input stages. The UNSPSC code for this product is 39122004.

RTAC-01-KIT
The Pulse Encoder Interface module offers a differential or single ended interface for a digital pulse encoder. The module is capable of operating from either a 15 or 24VDC signal with a max frequency of 200kHz. This option uses 55 mA of the available 250 mA power supply. When the drive’s internal power supply is used to power the encoder, additional options may not be installed. Check the encoder’s power supply requirements prior to installation.
SDCS-DSL-4
The DSL-4 board provides a drive-to-drive communication dedicated to the DCS800, based on CAN bus. This communication adapter is also used in 12-pulse operation and communication/control of external field supplies. It is standard on D4+ and D5-D7.
