Eaton Meets Evolving Communication Demands for Industrial, OEM Customers with New Connectivity Options for Motor Protection

Single Communications Card Provides Four Protocols, Includes Ethernet/IP and Modbus TCP

February 22, 2012 Pittsburgh … Diversified industrial manufacturer Eaton Corporation is expanding communications options across its motor protection and soft starter solutions to better serve industrial and OEM customers. The new C441 Ethernet series of communications cards allow customers to select from Ethernet/IP, Modbus TCP, HTTP web services and Modbus RTU communication protocols in a single card. The added communications provide electrical original equipment manufacturers (OEMs) and industrial customers, as well as machinery OEMs and panel builders, with flexible communication options to configure, control and monitor their systems.

"The new connectivity options help electrical and machinery OEMs and industrial users address problems before they cause downtime or excessive energy waste," said Adam Krug, product manager at Eaton. "Integral web services allow for configuration, control, monitoring and diagnostics. Also, the flexibility in communications allows OEM customers to add value to their equipment with simple and desirable features, like supervision and control."

This latest offering is compatible with Eaton C440, XTOE and C441 electronic motor protection relays, S611 soft starters, and can be used as stand-alone input/output (IO). Now, the suite of protocols available for Eaton motor protection and soft starter solutions includes PROFIBUS, Modbus TCP and RTU, DeviceNet, and Ethernet IP.

Integral web services provide an easy-to-use web-based graphical user interface (GUI) to make it easier to recognize potential problems. Using a laptop or smart device, customers can drill down to a given load by simply entering an IP address into their web browser. With four levels of access, the cards ensure only those with credentials have access to critical or sensitive functions.

Problems can be addressed in real time with intelligent monitoring readouts from starters and onboard available four digital inputs (120 volts alternating current or 24 volts direct current) and two discrete relay outputs. With a dual port switch, the Ethernet card allows for easy daisy chaining and reliable ring configurations. Additionally, customers have the ability to use one network for control and another for monitoring – through the Modbus serial protocol used in parallel with the Ethernet network –allowing redundant communications and greater reliability with a single card.
