Description

The ABB AI815 Analog Input Module is a versatile component designed for use in industrial automation systems, offering 8 channels that can be configured for either voltage or current inputs. This module ensures reliable performance with features like overvoltage and undervoltage protection, current-limited transmitter supply, and HART pass-through communication. Each input channel provides high input resistance for voltage inputs and precise input resistance for current inputs, ensuring accurate and stable signal processing. The module is ideal for applications requiring single-ended unipolar inputs and provides group isolation from ground.

Features and Benefits

• 8 Channels: Supports 0...20 mA, 4...20 mA, 0...5 V, or 1...5 V DC single-ended unipolar inputs.
• Isolation: One group of 8 channels isolated from ground.
• High Resolution: 12-bit resolution for precise signal measurement.
• Current Limited Transmitter Supply: Built-in current limited power supply for each channel.
• HART Communication: Pass-through HART communication for enhanced data transfer.
• Robust Protection: Withstands overvoltage or undervoltage of at least 11 V DC.
