ARDBOX PLC Relay, Arduino based PLC (GPRS)
Description
- ARDBOX PLC Relay, Arduino based PLC (GPRS)
- Versatile with 8 relay outputs & 10-bit analog inputs
- Long-range LoRa & GPRS for remote applications
- High-speed WiFi & BLE integration
- Arduino-based for easy programming
- Expandable via I2C with up to 127 modules
The ARDBOX PLC Relay, Arduino based PLC (GPRS) is an advanced programmable logic controller that integrates multiple communication technologies to cater to a variety of industrial automation needs. It features eight 10-bit analog inputs and two digital optoisolated inputs, along with eight relay outputs for comprehensive control and interfacing capabilities. The device supports a range of industrial communication protocols including I2C, RS232, RS485, and SPI, allowing for versatile connectivity options.
Equipped with LoRa connectivity, this PLC benefits from the Long Range modulation's ability to cover wide areas and its high resistance to interference. LoRas Chirp Spread Spectrum (CSS) modulation, originally used in military operations, offers high tolerance to interference, exceptional receiver sensitivity, and low power consumption. It is particularly suitable for applications requiring long-range communication, such as Smart Grid Management, Logistics and Fleet Management, Environmental Monitoring, Industrial IoT, and Smart Cities.

The PLC also includes GSM/GPRS connectivity, making it ideal for remote monitoring, data logging, and control. It allows for the customization of SMS messages with both static and dynamic content, which can be sent to predefined phone numbers triggered by various events such as input state changes or alarm thresholds.
Furthermore, the integration of WiFi and BLE technologies enables high-speed and secure communications with a wide range of digital devices. WiFi facilitates internet access without the need for wires, while Bluetooth allows for data exchange over short distances within the ISM 2.4 GHz frequency band.
The ARDBOX PLC is based on an Arduino platform, ensuring ease of programming and instant connectivity. It is designed to be flexible and dynamic, with standardized modules for uniform programming across the ARDBOX PLC family. The system is expandable through the I2C connection, supporting the potential connection of up to 127 modules for extensive input/output configurations.
Please note that the use of this device in certain frequencies is subject to regional regulations and compliance with the ISM Band requirements.

Refund Policy
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.
Please review the Return Conditions, Return Exceptions and the process on How to Request a Return Authorization (RA) before initiating a return request.
European consumers exercising their statutory Right of Withdrawal are subject to different conditions. See the Statutory Right of Withdrawal.
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.
- Professional & Specialized Equipment — See the Professional & Specialized Equipment Warranty page and Professional & Institutional Buyers (B2B) section in the Terms & Conditions.
* European consumers retain their statutory Right of Withdrawal on these items. Its exercise is subject to the conditions and exclusions set out in the Statutory Right of Withdrawal, and any reimbursement may be reduced to reflect a loss in value resulting from handling beyond inspection.
How to Request a Return Authorization (RA)
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, or contact us through our Support Center.
- 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]".
