ABB GDC801B101 3BHE051592R0101
3BHE051592R0101 GDC801B101
Product Name: ABB GDC801B101 3BHE051592R0101 Digital I/O Module
Brand: ABB
Series: ABB ACS800/ACS6000 frequency converter and UNITOL static excitation system matching control board
Product type: 8-channel digital input/8-channel digital output module (8DI/8DO)
Core function: As the on-site signal acquisition and control execution module in ABB medium and high voltage frequency converters and excitation systems, it is responsible for collecting switch signals from external devices (such as buttons, relay contacts, limit switches, sensor status, etc.) to the main control system, and driving external actuators (such as contactors, solenoid valves, indicator lights, etc.) in the form of relay outputs based on control instructions from the main control system. This module is a pure digital I/O version in the GDC801 series, used in conjunction with the same series GDC801A (Crowbar Crowbar Protection Board) to form a complete inverter/excitation system protection and control link.
