ABB DI04
The ABB DI04 is a digital input module belonging to the ABB S800 I/O Series, specifically designed for industrial automation control systems. It is used to collect on-site discrete signals (such as signals from buttons, limit switches, and relay contacts). This module provides high-density and high-reliability signal input interfaces, making it suitable for distributed I/O systems in industries including power, petrochemical, and water treatment. It ensures the accurate collection and transmission of control signals.
The core values of the DI04 are as follows:
High channel density: 16-channel digital input, saving installation space.
Electrical isolation: Isolation between channels and at the system level, providing strong anti-interference capability.
Flexible configuration: Supports dry contact/wet contact input, adapting to a variety of on-site equipment.

Structure and Composition
The DI04 adopts a compact modular design, with main components including:
Input Signal Conditioning Circuit
16-channel optocoupler isolation input, supporting automatic identification of dry contacts/wet contacts.
Configurable filtering circuit (1ms/10ms/50ms) to suppress contact bounce.
Backplane Interface
Interacts with the S800 backplane through a high-speed connector, transmitting data to the controller (e.g., AC 800M).
Status Indicators
Each channel is equipped with an LED to display the input status (green = activated, off = deactivated).
Terminal Block
Pluggable screw terminals, supporting front-wiring (no need to disconnect the backplane).
Metal Enclosure
Provides EMI shielding and mechanical protection, complying with industrial anti-vibration standards.
Main Features and Advantages
High-reliability Signal Collection
500V AC isolation effectively prevents ground loop interference and on-site noise.
Wide input voltage range (0-30V DC), compatible with various sensors and switches.
Flexible Configuration and Fast Response
Adjustable filtering time (1ms/10ms/50ms) to adapt to different signal types (e.g., emergency stop signals require fast response).
Automatic adaptation to dry contacts/wet contacts, no need for hardware jumpers.
Seamless System Integration
Natively compatible with the ABB AC 800M controller and S800 I/O system, enabling plug-and-play functionality.
Automatically identifies modules and configures parameters via the Control Builder M software.
Industrial-grade Durability
Wide operating temperature range from -25°C to +70°C, suitable for harsh industrial environments.
Complies with IEC 61131-2 and UL 508 standards.
Installation and Maintenance
Installation Key Points
Perform operations with power off (or confirm that the system supports hot swapping).
Use shielded twisted-pair cables for signal lines, with the shield layer grounded at one end (control cabinet side).
An external 24V DC power supply (e.g., ABB SD822 power module) is required for wet contact input.
Maintenance Recommendations
Regularly check the tightness of terminals (they tend to loosen in vibrating environments).
Diagnose channel faults through LED status lights (e.g., a constantly on light indicates a line short circuit).
