SKU: QEC-RXXJT3S Category: Tag:

ICOP’s QEC-RXXJT series are standard industrial EtherCAT slave junction modules, with standard EtherCAT junction modules and fiber optics modules. Supports flexible wiring configurations in line, tree, and star topologies, allowing EtherCAT systems to remain operational if a machine error requires a shutdown.


Complying with the EtherCAT Conformance Test Tool (ET9400), the QEC-RXXJT is qualified and can cooperate with most third-party EtherCAT master systems for quick implementation in industrial applications.

The QEC-RXXJT3S module, featuring an SC duplex socket for fiber-optic connections, enhances EtherCAT networks by enabling the creation of star topologies using 100BASE FX hardware. This flexibility is further amplified by the module’s ability to connect seamlessly into any position within an EtherCAT Terminal segment. Multiple QEC-RXXJT3S units can be used together for expansive network configurations to form a modular EtherCAT star hub. The key advantage of this module is its impressive reach, offering connection distances of up to 20 kilometers with multi-mode glass fiber, ideal for large-scale industrial applications.

The QEC-RXXJT series can also monitor hardware information on temperature, voltage, current, and startup time (hr). These features allow users to track the system’s carbon footprint and estimate its lifespan.

The QEC-RXXJT series measures 107.45 x 77.4 x 30 mm and supports standard system operation from -20 to +70°C. It can be easily installed by Din Rail mounting kit and features a European-style terminal block that provides easy installation and removable wiring terminals for easy deployment.
