The revolutionary SmartWire-DT system from Eaton’s Electrical Sector, which virtually eliminates the need for conventional control wiring in panels and on machines, is now even more versatile and convenient. This follows 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 make it possible to implement sophisticated control systems without the need to use programmable controllers (PLCs), which means big savings in costs and complexity. In addition, Eaton’s easySoft-Pro software makes easy800 relays simple to program, 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 straightforward and well-known ladder diagram techniques. 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 intuitive software package.
Equally well suited for use in control systems based on easy800 relays, and those based on conventional PLCs, 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 via the SmartWire-DT connection a wide range of operating parameters that include motor current, motor fault conditions and overload status. This is achieved without the need for additional hardware like current transformers and specialist relays, which are not only costly to buy, but are also inconvenient to fit and wire.
A key benefit of the information supplied by PKE units with SmartWire-DT connectivity is that, in many cases, it allows developing problems to be identified and addressed before a motor trip occurs, thereby greatly reducing downtime and costly production losses.
SmartWire-DT from Eaton is a powerful and 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.

With its latest ranges of compact yet versatile timing relays, Moeller Electric now offers convenient and cost-effective timer options covering virtually every control panel and power distribution application.
Special features of the Moeller Electric timer family include models for operation direct from 400V supplies, which are ideal for use in three-phase systems where no neutral is available, models with remote adjustment facilities, and ultra-compact versions just 17.5mm wide, which save valuable space in distribution boards.
Featuring the same design and dimensions as the popular DILEM contactors, DILET timers are well suited for control panel applications. They are available in three types, the DILET 11-30 which is an economical option where an on delay of between 1.5 and 30s is required; the DILET 11-M which also offers an on-delay function, but has ten timing ranges covering 0.5 seconds to 60 hours; and the DILET 70 multi-function relay which offers a choice of eight timing functions as well as the option of adjusting the setting with a remote potentiometer.
DILET timers can be supplied in universal versions for use with AC and DC supplies anywhere in the range 24V to 240V, and for 400V AC operation.
For applications where maximum versatility is required from a compact timing relay, Moeller Electric offers the ETR4 range. Just 22.5mm wide, these DIN-rail mounting units cover times of 0.05s to 100h in ten ranges, and offer a choice of different timing functions. The range offers a basic on-delayed timer, a star-delta timing relay and two multi-function relays, ETR4-69 and ETR4-70 offering eight timing functions. The ETR4-69 has a single changeover output contact, while the ETR4-70 has two changeover contacts and also allows the connection of a potentiometer for remote adjustment.
Both the ETR4-69 and ETR4-70 have an opto-isolated input to allow timing to be initiated from almost any kind of external circuit, and both incorporate LEDs that give a clear indication of current status.
Moeller Electric’s ultra-compact ETR2 timing relays have been specifically designed for use in distribution boards, and are the same size as most miniature circuit breakers. In spite of their small dimensions, they offer a timing range from 0.05s to 100h, and are available in six different versions, including a multi-function model. All ETR2 relays are suitable for use with AC and DC supplies in the range 24V to 240V.
