ABB 07AI91E GJR5251600R0202
Model interpretation: “07AI91” is the code name for the Advant OCS series 8-channel analog input module family. The suffix “E” represents that this version has electrical isolation function, which can effectively suppress common mode interference and is suitable for industrial sites with strong electromagnetic interference.
[Core Function]
This module is specifically designed for industrial automation process control and monitoring scenarios, responsible for collecting and converting analog signals from on-site sensors into digital signals for use by upper level control systems. Support simultaneous access of multi-channel analog signals, compatible with commonly used industrial voltage signals (0 to 10V DC) and current signals (4 to 20mA), capable of independent acquisition and processing of signals from different channels, ensuring comprehensive monitoring of multiple process variables by the system. The electrical isolation version (E suffix) adds an isolation barrier between the signal input terminal and the system, greatly improving the ability to resist common mode interference, and is suitable for application environments where strong interference devices such as frequency converters and high-power motors coexist.
