Engineered for complex electromagnetic environments
Supports speeds up to 115.2Kbps
Safeguards with 2500V isolation and surge protection
Operates stably over distances exceeding 1200m
Detects data flow direction for reliable conversion
The Industrial RS485 Opto-Isolated Hub is engineered to fulfill the demands of large-scale RS485 systems operating in complex electromagnetic environments. It supports data transmission speeds up to 115.2Kbps and employs photoelectric isolation technology to safeguard against lightning surges, ensuring the safety and reliability of data communication. The hub features a built-in opto-isolator and a 600W surge protection circuit, providing an isolation voltage of 2500V to effectively suppress interference such as surges and electrostatic discharges.
This hub is capable of stable operation over transmission distances exceeding 1200 meters in RS485 mode. It includes a discrimination circuit that automatically detects data flow direction and switches the enable control circuit, addressing the issue of RS485 transmission and reception conversion delay. This makes it highly suitable for power acquisition systems and other applications requiring reliable data interface conversion.
The hub facilitates a star RS485 bus connection, with each port offering short-circuit and open-circuit protection. Users can enhance the RS485 bus structure, segment networks, and improve communication reliability. In the event of lightning strikes or equipment malfunctions, the hub isolates the faulty network segment, allowing other segments to function normally, thereby enhancing the reliability of the RS485 network and reducing maintenance time.

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.
