NEIO Series: EtherCAT I/O Modules That Simplify Factory Automation

Are you in need of a compact and convenient EtherCAT solution to meet your factory automation needs? NexCOBOT, a NEXCOM subsidiary, is proud to showcase the NEIO family of EtherCAT slave I/O modules, a welcome addition to your own set of master controllers. With its industrial-grade certification, user-friendly design, and rich selection of I/O combinations, the NEIO series is the choice that’s most cost-effective and easiest to install for machine control and robotic control applications.

Enjoy the intuitive design

Setting up an assembly line is no easy task. That’s why NexCOBOT makes the process as easy as possible, with all NEIO I/O modules featuring an uncluttered and user-friendly design. To ensure safety, you’ll notice that circuits are covered with protective smart latches, which prevent debris or other wires from accidentally falling into wiring slots when modules are placed in electrical control panels, thus avoiding costly short circuits. Additionally, stress-free maintenance is possible with the detachable screw terminals – remove wiring from the module or transfer existing wiring to another module. Quickly view I/O statuses and diagnose faults by viewing the front-facing LED indicators. And finally, to suit a variety of manufacturing environments, we provide multiple mounting methods (DIN rail and wall mounts).

Industrial certifications mean peace of mind

To ensure problem-free operation and compatibility with other devices in your factory, all NEIO series modules have passed the EtherCAT Conformance Test, after testing with other third-party master controllers. As automation sites are subject to electromagnetic interference, our modules have also been tested for EMC against IEC EN 61000-6-2 and EN 61000-6-4, as well as received CE/FCC Class A certification. Moreover, they provide three-way isolation (LAN, power, and I/Os) and protection against surges, shocks, and vibration.

Mix and match till you’re content

The NEIO series is perfect for industrial environments with assembly lines and individual machinery. Supporting high-density I/Os of up to 32 points, they connect specifically to machine control and robotic control devices. Digital I/Os can link to any of our B1811/1812 modules (B1101/1102 DI only, B1201/1202 DO only), and analog I/Os to the B1841/B1842. We also have models for other specific needs: such as the B1603 for serial communication and B1851 for encoders. Likewise, the NEIO EtherCAT slaves match perfectly with our EtherCAT motion controllers, the NexMotion NET series.
