ABB Analog Input Output Module 8AI/8AO AX522 The ABB AX522 Analog Input/Output Module 1SAP250000R0001 is a versatile and commonly used I/O expansion module within ABB’s AC500 series of Programmable Logic Controllers (PLCs). It’s designed to provide a comprehensive solution for applications requiring. Key Features and Functionality: Combined Analog I/O: The AX522 is the analog inputs and outputs, making it highly flexible for various process control applications. 8 Analog Inputs (AI): Each input channel can be individually configured to accept a variety of standard industrial analog signals, Supports common types like Pt100, Pt1000, and Ni1000. This is crucial for temperature measurement applications. 8 Analog Outputs (AO): Signal Types: The outputs are configurable for: Voltage (U): Typically 0 V to 10 V, and -10 V to 10 V. Current (I): Typically 0 mA to 20 mA, and 4 mA to 20 mA. Output Configuration: While it has 8 AO, the configuration is often split. Commonly, 4 outputs support both Voltage (U) and Current (I), while the remaining 4 outputs support only Voltage (U). Resolution: 13-bit resolution (including sign) for analog outputs, ensuring precise control of actuators.
