ABB DI811 3BSE008552R1 Digital Input Module

The ABB DI811 is a Digital Input Module designed for use in ABB's S800 I/O system, which is part of ABB's distributed control systems (DCS) such as the Advant Controller 800 and AC 800M families. Below is a detailed description of the DI811 module:

Key Features and Specifications of ABB DI811:

1. Type: Digital Input Module.

2. Number of Channels: The DI811 provides 16 digital input channels, which can be used to receive signals from various field devices (e.g., switches, sensors, or other contact-based input devices).

3. Voltage Range:

   • Input signal type: 24 V DC.
   • Nominal voltage range for inputs is 18-30 V DC.

4. Input Type:

   • Designed for 24 V DC input signals.
   • The module supports signals in the IEC 61131-2, Type 1 and Type 3 categories.

5. Isolation:

   • The module provides optical isolation between the field inputs and the system's internal electronics to protect the system from electrical faults.
   • Grouped isolation: Inputs are grouped into 2 sets, with 8 inputs per group, allowing for isolated sections.

6. Signal Status Indication:

   • Each input channel has an LED indicator, providing visual feedback on the status of the input signals, which simplifies troubleshooting and diagnostics.

7. Mounting: The DI811 module is designed to be mounted on ABB's S800 I/O terminal units, like the TU830 or similar termination units, which handle field wiring.

8. Power Consumption: The power consumption of the DI811 module is low, typical for digital input modules.

9. Diagnostic Functions: The module supports diagnostics to detect common wiring issues, such as open circuits, to help maintain system reliability and minimize downtime.
