The Waveshare Industrial 8-Ch Analog Acquisition Module, 12-Bit High-Precision, Supports Voltage & Current Acquisition (0~10V) is an advanced industrial-grade module designed for precise analog data acquisition. It supports both voltage and current acquisition across eight channels simultaneously, utilizing a 12-bit high-precision system. The module operates on a wide voltage power supply range of DC 7~36V and communicates via the Modbus RTU protocol, ensuring compatibility with various industrial systems.
This module is equipped with multiple protective features, including power and magnetic isolation, a resettable fuse, and transient voltage suppression (TVS), which enhance its reliability and resistance to interference. It offers configurable device addresses, allowing for cascading multiple devices on an RS485 bus. The module's design includes a rail-mount case for easy installation and stacking, making it suitable for environments with stringent requirements.
The module supports a variety of input modes, including single-ended and differential inputs, and allows for simultaneous voltage and current acquisition. It incorporates high-precision resistors and a zero-drift operational amplifier to ensure accurate data collection. Additionally, it features a built-in oversampling digital filtering algorithm and an onboard watchdog to maintain stable output.
The module's robust design includes industrial-grade isolated protection, ensuring stable voltage and current output, and is equipped with ESD protection for analog inputs. It supports multiple configurable ranges and is designed for easy integration into industrial applications requiring high precision and reliability.

If you are not satisfied with a product purchased from the Site, you may request a return within 30 days from the delivery date, unless the product is listed under the Return Exceptions below or is subject to specific return conditions noted on the product page.
This return policy also applies, as a minimum standard, to products sold and fulfilled by third-party vendors through the Marketplace.
Returns under this policy concern non-defective products. In the case of a confirmed manufacturing defect, remedies are handled under the Warranty terms, at the Vendor's discretion. See the Warranty section.
Return Conditions
To qualify for a refund under the 30-day return policy, all of the following conditions must be met:
A valid Return Authorization (RA) number must be obtained prior to returning the product. Returns without an RA number will be refused.
The RA number is valid for 30 days. The returned item must be received within that period.
The RA number must be included with the return.
Products must be returned in unused, unmodified condition (e.g., no scratches, alterations, missing parts, or signs of installation/use) and in their original packaging, suitable for resale.
Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
RobotShop Fulfilled Orders → submit a support ticket from your account under My Support Tickets.
Marketplace Vendor Orders → submit a ticket from your account under My Marketplace Tickets to contact the vendor directly.
Note: Marketplace vendor products are normally labelled with SKUs starting with RM, and identified on the product page with the mention "Sold and fulfilled by [Vendor Name]".
