The ABB DI620 module is part of ABB’s S800 I/O family. It is typically used in industrial automation and control systems, particularly for applications that require monitoring or controlling digital inputs.
Product Name:
ABB DI620 Digital Input Module
Product Description:
The ABB DI620 is a digital input module used in industrial control systems, typically for monitoring digital signals (e.g., ON/OFF, high/low) from field devices like sensors, switches, or relays. This module is part of ABB’s S800 I/O range, designed for integration with ABB’s automation and control systems. The DI620 module can handle various digital input types and provide reliable communication to a central control system.
The module features a compact design, easy configuration, and high reliability in harsh industrial environments. It is often used in systems where the need for digital signal acquisition from equipment or machines is critical, such as in process control, manufacturing, and energy industries.
Product Parameters and Specifications:
- I/O Type: Digital Input

Product Use:
The ABB DI620 module is primarily used to monitor digital signals from industrial field devices and equipment. These digital signals may include:
- Sensors: Detecting the presence or absence of objects, level detection, etc.
- Switches: Simple on/off control signals.
- Pushbuttons or Indicators: Status monitoring in a control circuit.
- Relays: For switching operations in control loops or safety systems.
Applications include:
- Process Control Systems: Monitoring switches or sensors in pipelines, reactors, or conveyors.
- Factory Automation: Managing signals from machines, assembly lines, and safety devices.
- Building Automation: Collecting input from switches or sensors in HVAC, lighting, or security systems.
- Energy Management: Monitoring status of circuit breakers or protection relays in substations or power plants.
- Safety and Alarm Systems: Input from emergency stop buttons, safety interlocks, or status indicators.
The DI620 module is generally integrated into larger control systems and used with additional modules for controlling outputs, providing a comprehensive solution for automation tasks.
