Waveshare Industrial 8-Ch Analog Acquisition Module with 12-Bit High-Precision Voltage & Current
The Waveshare 8-Ch Analog Acquisition Module is an industrial-grade 8-channel analog input module designed for accurate monitoring and data collection from voltage and current sensors. It provides 12-bit resolution, a sampling accuracy of ≤3%, and an update rate of 25Hz, allowing all 8 channels to be acquired simultaneously. The module supports configurable input ranges of 0–5V, 1–5V, 0–20mA, and 4–20mA, with both single-ended and differential input modes.
Communication is handled through RS485 using the standard Modbus RTU protocol, with baud rates from 4800 to 256000 bps and a default setting of 9600, N, 8, 1. It operates from a wide DC 7–36V power supply and supports device addresses from 1–255, making it suitable for multi-device RS485 networks. Built-in power isolation, magnetic signal isolation, TVS protection, a resettable fuse, and protection circuitry improve reliability in industrial environments.
Features:
• Cascade several devices on the RS485 bus with configurable device addresses (1-255).
• Onboard voltage regulator supports 7-36V power supply.
• Onboard unibody power supply separation delivers stable isolated voltage and does not require an additional power source for the isolated terminal.
• Onboard unibody magnetic isolation provides signal separation, great dependability, and powerful anti-interference.
• Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, providing over-current/over-voltage proof, lightningproof, and anti-electrostatic
• Supports 12-bit high-precision acquisition with numerous range input modes, single-ended/differential input, and simultaneous acquisition of voltage and current.
• Uses high-precision resistors and a zero-drift high-precision operational amplifier for more precise data gathering.
• Onboard watchdog and built-in oversampling digital filtering technology ensure reliable output without crashing.
• Rail-mount case design, supports stacking combinations, is simple to install and safer to use.
• 3x LEDs to indicate the MCU and signal transceiving status.
