ABB DI811

Operating Parameters

Input Channels:16 digital input channels, organized into two isolated groups of eight.

Voltage Specifications: Each channel is designed for 48 V DC inputs with current sinking characteristics.

Input Impedance: With an input impedance of around 10 kΩ.

Response Time: The response time is less than 1 ms.

Operating Temperature Range:- 25 °C to + 60 °C.

Input Status Indicators: Each channel is equipped with LED indicators to display the input status, facilitating easy monitoring and diagnostics.

Product Features

High Precision Signal Detection:The ABB DI811 is specifically optimized for accurate and precise signal detection. ABB DI811 is capable of recognizing multiple levels of digital input, allowing for stable and effective performance in noisy or uncluttered environments.

High Speed: The ABB DI811 is able to respond quickly to input signals due to its fast response time, making it crucial for high speed manufacturing processes or real timing monitoring systems where data acquisition is key.

Configurable over the air: The ABB DI811 can be easily configured to suit the needs of applications So, you can set up when you're going to use this module to mitigate overhead when it already has been adjusted for different scenarios.

Signal Isolation: Each input channel features an optical isolation barrier. This isolation provides protection for both the module and the attached equipment against electrical transients, short circuits, and ground loops, which improves reliability and safety in the system as a whole.

Process Voltage Supervision: Built in process voltage supervision increases reliability of the system by monitoring the input voltage levels and notifying the operators for any improper conditions.

Optical Isolation: All input channels come with optical isolation, preventing interference from any electrical activity and ensuring the integrity of each input signal.

Installation

Mounting Type: Typically, ABB DI811 comes with a DIN rail mounting feature. The installation is ensured with the help of a latching device snapped onto the DIN rail and appropriately grounded.

Wiring Connection: It is possible to connect the module with 3 - wire connections for full installation of I/O modules. As well as fuses and field power distribution. Dedicated I/O and zp connections to field wiring is provided for each channel. Each of these two isolated groups has a 6.3 A fuse, and the process voltage can be connected to them.

Data: Configuration Setup: After the physical installation, the module must be configured in the control system. This can include signals such as digital input, TTL, CMOS, filter modes, network addressing, and other parameters.
