  • Description

    NX3A1_ & NX3M1_ NEXUS Networked I/O PLS Controller

    The AMCI NEXUS PLS Controller integrates high-speed programmable limit switch functions with a direct network connection. These units operate independently from, yet communicate data and status to, the main system controller. Program files are downloaded for all output setpoint functions while operational data is available over the network. Typical applications are packaging machine controls, high-speed assembly, and food and beverage machine applications.

    The NX3A1_ uses a single resolver transducer as the position sensor while the NX3M1_ uses an incremental encoder.

    Both units have two modes of operation, Independent Mode and Group Mode, both of which feature speed compensation (Auto Advance). Configured using the Independent Mode, each output is independent of the others and has a corresponding input that is ANDed with the output.

    Configured using the Group Mode, the outputs are combined into one of six groups. Each group is assigned an Operating Mode that condition how the outputs fire. This configuration replaces the ladder logic that you would typically have to write for such packaging functions as glue gun control or material sensing. In either mode, the programmable limit switch outputs are updated every 100microseconds.

    PLC-Based Specialty I/O Solutions

    Functionally, the AMCI NEXUS controllers and interfaces deliver the same level of PLC integration as their plug-in module counterparts, but with much more flexibility from a systems standpoint. Rather than limit these versatile products to one PLC brand or specific backplane, all units are Din-rail mountable and equipped with a network interface that allows connection to various controllers. AMCI NEXUS specialty I/O integrate with ANY network enabled PLC using Ethernet I/P, Modbus TCP/IP, Profinet, Profibus, ControlNet, or DeviceNet.

    The flexibility of a NEXUS controls solution saves time and money, letting customers choose whatever PLC best meets their needs, or change PLCs without having to re-specify and repurchase plug-in modules. And because the NEXUS integrates via network communication, PLC platforms no longer restrict compatibility and integration.
