07AI91 GJR5251600R0202 ABB Analog input module High precision multi channel industrial grade reliability
Product Overview
ABB 07AI91 is a high-performance 8-channel analog input module, specifically designed for ABB automation control systems, used for precisely collecting analog signals from sensors, transmitters and other devices. This module supports multiple standard industrial signal types, including voltage and current inputs, and features high precision and long-term stability. It is widely used in industries such as power, chemical engineering, water treatment, metallurgy, and HVAC.
Core features
8 independent analog input channels
Support multiple signal types
Current input: 4-20 mA
Voltage input: 0-10V, ± 10V
High precision and resolution
Accuracy: ±0.1% of full scale (typical value)
Resolution: 16 bits
Built-in isolation protection: Electrical isolation between each channel enhances anti-interference capability
LED status indication: Each channel is equipped with a green operation light, and the module panel integrates a fault (ERR) indicator light
Supports hot plugging: Can be safely replaced during system operation (with redundant power supply and controller required)
Technical parameters
Power monitoring system: It is used to collect data from smart meters and transmitters
Chemical industry: Monitoring of parameters such as pressure, temperature and flow rate of reaction vessels and storage tanks
Water treatment plant: Status feedback for key equipment such as pumping stations and valve controllers
HVAC system: Precise control of air flow, temperature and humidity in building automation
Energy management: Measurement of key parameters for facilities such as boilers and steam pipelines
Installation and wiring instructions
Hardware installation: Insert the 07AI91 into the TB820V1 (screw terminal) or TB840A (spring terminal) base.
Wiring specification
Current input: Connect to the positive and negative terminals of the sensor, and pay attention to the polarity
Voltage input: Use shielded cables, with the shield layer grounded at a single point
Configuration Settings: In Control Builder M, select the input type (mA/V), range and engineering unit for each channel.
Diagnostic function: Supports open-circuit detection (only available in 4-20mA mode). When a fault occurs, the ERR light will turn on and report to the controller.
