  • Description

    RBE2-8 Ethernet Relay Board

    AMCI's RBE2-8 is an eight-output relay board that accepts AC and DC solid state relays. The RBE2-8 can drive high power loads while allowing you to lower wiring cost by placing the RBE2-8 close to those loads and running a single network cable back to the host controller. 

    The host controller can be updated to any future platform that supports EtherNet/IP, PROFINET, or Modbus TCP and the RBE2-8 will operate with the new system.

    PLC-Based Specialty I/O Solutions

    Functionally, the AMCI Ethernet Relay Boards 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 Ethernet Relay Boards integrate with ANY network enabled PLC that supports EtherNet/IP, Modbus-TCP, or Profinet.

    The flexibility of AMCI's Ethernet Relay Boards offers you a sustainable solution that 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 AMCI's Ethernet Relay Boards integrate via network communication, PLC platforms no longer restrict compatibility and integration.

    Compatible Networks


    AMCI's Ethernet Relay Boards are compatible with any networked PLC that supports these networks.

    The Best PLC Integration Available

    AMCI products are uniquely designed to provide the best PLC integration available. Unlike other products that require a separate software package for configuration or operation, AMCI's PLC-based products are programmed using your PLC's software - nothing new to buy or learn!

    Our expertise with the leading PLC manufacturers (e.g. Allen-Bradley Schneider, GE, etc) is unmatched when it comes to high performance Specialty I/O, Position Sensing, and Motion Control technology.
