June 18, 2025 – AutomationDirect has added Define Instruments Twin Link series point-to-point wireless I/O devices, which provide a cost-effective solution for applications where wiring is difficult or impractical, such as long distances, physical obstacles, or moving equipment. They create a dedicated, bidirectional radio link between a pre-paired set to reliably transmit analog or digital signals with minimal setup. The signals can be transmitted up to 0.9 miles line-of-sight or 500 feet through walls, and up to 15 repeaters can be used to improve the signal path or extend the range.
The sender/receiver pair accepts thermocouple, RTD, mA, or frequency inputs and provides two isolated 4–20 mA outputs for seamless integration with control or monitoring systems. Discrete I/O is also included to support advanced control, alarms, or transparent signal pass-through. The free Define ToolBox software simplifies configuration and includes advanced features such as signal simulation, configuration export, and PDF documentation.
Define Instruments Twin Link series point-to-point wireless I/O devices are CE marked, RoHS compliant, and offer a 5-year warranty.
The Twin Link point-to-point wireless I/O sender/receiver pair is priced at $614.00 (DEFINE-TWIN-LINK) and repeaters are priced at $236.00 (DEFINE-REPEATER).
