Overview

The ABB GDC801B101 is a versatile control board used in distributed control systems (DCS) and programmable logic controller (PLC) environments. Engineered for precision and reliability, it features 8 digital inputs, 8 digital outputs, and a 14-bit analog-to-digital converter for accurate voltage and current measurements. Moreover, its modular design and compact footprint (110 × 76 × 23 mm) make it ideal for space-constrained installations.

In addition to its I/O capabilities, the GDC801B101 supports hot-swapping, allowing maintenance without system shutdown. Therefore, it’s widely adopted in mission-critical applications such as power plants, chemical processing, and manufacturing automation. The board is manufactured in Switzerland and meets global industrial standards for performance and safety.

For instance, engineers deploying this module in multi-cell battery systems benefit from its 1% measurement accuracy and broad operating range of 3.6V to 60V. In addition, its robust build and low power consumption (24 VDC input) ensure long-term reliability.
