SmartWire-DT just got smarter

24 May 2012

Eaton's SmartWire-DT panel component interconnection system, which virtually eliminates the need for conventional control wiring in panels and on machines, is now even more versatile and convenient following the addition of devices with integral SmartWire-DT connectivity to two key product ranges – easy800 control relays and PKE motor-protection circuit breakers.

In many applications, easy800 programmable control relays with SmartWire-DT enables sophisticated control systems to be implemented without having to a use programmable controller (PLC), which means big savings in costs and complexity. In addition, Eaton’s easySoft-Pro software makes easy800 relays simple to programme, even for users who have no specialist programming knowledge or experience.

The new easy800 relays are suitable for applications with up to 320 I/O and are programmed using the industry-wide ladder diagram technique. The easySoft-Pro programming software now includes SmartWire Assist to configure external devices, allowing control systems that incorporate the new relays to be drawn, configured, programmed and tested using just this one software package.

The PKE motor-protection circuit breakers with SmartWire-DT allow users to monitor the operation of their motors in detail and in real time. The PKE units can report a wide range of operating parameters via SmartWire-DT, including motor current, motor fault conditions and overload status. This is achieved without the need for additional hardware like current transformers and specialist relays.

SmartWire-DT is a versatile communications system that enables switching and control devices, such as contactors, circuit breakers and pushbuttons, as well as analogue I/O devices, to be connected quickly and simply using pre-fabricated plug-in cables. This saves time in building and testing control systems, as well as virtually eliminating the risk of wiring errors while greatly increasing the ease with which future modifications can be made.
