Waveshare 8-Channel Industrial Analog Output Module
High-precision 12-bit DA conversion
Dual-mode: 0~20 mA / 0~10V outputs
Robust Modbus RTU over RS485
Built-in surge & isolation protection
Easy rail-mount installation
The Waveshare 8-Channel Industrial Analog Output Module w/ 12-Bit DA Conversion (Modbus RTU) is designed to meet the rigorous demands of industrial environments. This module facilitates eight-channel simultaneous analog output, capable of both voltage and current modes. It features a 12-bit digital-to-analog conversion for high-precision output data and adopts the Modbus RTU protocol for communication. The device is equipped with built-in protection circuits, including power and magnetic isolation, which enhance its reliability and anti-interference capabilities.
The module allows for configurable device addresses, enabling the cascading of multiple devices on an RS485 bus. It includes an onboard voltage regulator compatible with a wide range of power supplies and integrates unibody power supply isolation to deliver stable isolated voltage without the need for an additional power source. Additionally, the module's magnetic isolation ensures signal integrity and robustness against interference.
For enhanced circuit protection, the module is outfitted with a resettable fuse and a Transient Voltage Suppressor (TVS), which work together to mitigate surge voltage and transient spikes, while also providing over-current and over-voltage protection. The onboard watchdog contributes to stable output performance. The module's rail-mount case design facilitates easy installation and secure stacking for multiple modules.
The module supports two output modes: a current output with a range of 0~20mA and a voltage output with a range of 0~10V. It is capable of sending Modbus RTU protocol commands via an RS485 interface and outputting data to sensors within the specified ranges. The industrial-grade isolated protection ensures stable operation, with dual isolation for both power and signal on the RS485 communication interface. The module's construction includes a built-in fuse and anti-reverse protection, further enhancing its suitability for challenging industrial settings.
Please note that the module should be handled with care, considering the built-in protection against lightning and electrostatic discharge. Proper installation and maintenance are essential to ensure the module's performance and longevity.

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]".
