ABB AX521 Analog Input/Output Module

Description

The ABB AX521 Analog Input/Output Module is a dedicated industrial I/O component designed for integration with ABB AC500 and S500 series PLC systems, enabling bidirectional conversion between analog and digital signals to support industrial process monitoring and control. It features 4 configurable analog input channels and 4 configurable analog output channels, all with 12-bit resolution. Input channels support multiple signal types including 0-10V, ±10V, 0/4-20mA, PT100, PT1000, and NI1000, while output channels deliver signals of ±10V and 0/4-20mA. Key technical features include high-precision A/D and D/A converters for accurate measurement and control, channel-to-channel isolation for strong anti-interference performance, and software-configurable input/output ranges for flexible adaptation to diverse industrial requirements. The module uses a modular design for easy installation and maintenance, and its industrial-grade construction ensures reliable operation in harsh industrial environments. It also offers broad compatibility, including support for connection to various fieldbuses via plug-in technology, compatibility with ABB MicroFlex E190 and Motiflex E180 servo drives, and optional Modbus TCP client functionality via firmware upgrade. Powered by 24VDC, it serves as a versatile solution for analog signal processing in industrial automation setups.
