Connectivity and compatibility

The ICD116A supports multiple serial communication standards, making it compatible with a wide range of industrial devices such as PLCs, remote terminal units, and sensors. Its fiber optic interface ensures immunity to electromagnetic interference, which is critical in electrically noisy environments like substations or manufacturing floors. The ability to form ring topologies allows flexible network designs that enhance redundancy and reliability.

Performance and reliability

Designed for demanding industrial and utility applications, this extender maintains stable communication even under extreme temperature fluctuations and mechanical stress. The triple isolation feature safeguards sensitive equipment from voltage surges and ground loops, reducing downtime risks. Compliance with rigorous industry standards further confirms its suitability for mission-critical installations where continuous operation is essential.

Installation and setup

Setting up the ICD116A is straightforward thanks to DIP switches that allow quick selection of the serial interface type and termination settings. Automatic data rate detection simplifies integration with existing equipment by adapting to the connected device’s communication speed. Its compact metal housing can be mounted easily in control cabinets or on DIN rails, fitting well into existing industrial infrastructure.

Ideal uses and environments

This fiber extender is well suited to industrial automation, utility substations, and defense sites where long-distance serial communication is required without compromising signal integrity. It fits environments that demand rugged hardware capable of withstanding temperature extremes, vibration, and electrical interference. Engineers working on building automation, generator controls, or substation relay systems will find this unit a reliable choice for extending asynchronous serial data links.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
