ABB GDC780BE IGCT Gate Driver Board

In stock

The ABB GDC780BE is a high-performance, redundant PROFIBUS DP master interface module for ABB Symphony Plus (S+) control systems (HN800 / HPC800 rack). It connects the controller to PROFIBUS DP-V0 / V1 / V2 field networks, supporting up to 125 DP slave devices at baud rates from 9.6 kbps to 12 Mbps, with native support for PROFIBUS PA via DP/PA linking devices.
