07AC91 GJR5252300R0101 ABB Analog output module High precision multi channel industrial grade reliability
Product Overview
ABB 07AC91 is a high-performance 4-channel analog output module, specifically designed for ABB automation control systems, used to precisely output control signals to actuators, control valves and other equipment. This module supports multiple standard industrial signal types, including current and voltage output, 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
Four independent analog output channels
Support multiple signal types
Current output: 4-20 mA
Voltage output: 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)
Seamless integration of Control Builder M: Automatically identify channel types and support online calibration and diagnosis
Technical parameters
Power monitoring system: It is used to control the data output of smart meters and transmitters
Chemical industry: Regulation of parameters such as pressure, temperature and flow rate of reaction vessels and storage tanks
Water treatment plant: Status control of key equipment such as pumping stations and valve controllers
HVAC system: Precise control of air flow, temperature and humidity in building automation
Energy management: Regulation of key parameters for facilities such as boilers and steam pipelines
Installation and wiring instructions
Hardware installation: Insert the 07AC91 into the TB820V1 (screw terminal) or TB840A (spring terminal) base.
Wiring specification
Current output: Connect to the positive and negative terminals of the load, and pay attention to the polarity
Voltage output: Use shielded cables, with the shield layer grounded at a single point
Configuration Settings: In Control Builder M, select the output 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.
