Waveshare Industrial 8-Channel Analog Acquisition Module, 0–10V, RS485 Modbus

Description

The Waveshare Industrial 8-Channel (B) Analog Acquisition Module is engineered for reliable data collection in demanding industrial automation and control systems. It provides eight high-precision analog input channels with 12-bit resolution, capturing signals with an accuracy of ≤3%. The module defaults to a 0–10V voltage input mode, which is fully configurable via software for compatibility with a wide range of industrial sensors and transducers.

Communication is handled through a magnetically isolated RS485 serial interface, supporting the standard Modbus RTU protocol for seamless integration into existing SCADA, PLC, or HMI networks. The design incorporates robust power and signal isolation, safeguarding sensitive measurement circuits from ground loops and electrical noise. With a wide operating voltage of DC 7–36V, comprehensive protection features (TVS, ESD, resettable fuse), and a DIN-rail mountable form factor, this module delivers a dependable solution for continuous monitoring in factory automation, process control, and environmental sensing applications.
