Finder's Astro 12.81 Time Switch Saves Energy Wherever You Are

Finder.jpg

Where the need exists to control lighting, temperature or other functions according to daylight hours, Finder’s Astro 12.81 time switch is an innovative, easily programmable time switch, which employs a unique digital program to calculate sunrise and sunset times by simply entering the location’s postcode with a single joystick. Its newest version now offers added flexibility, with the capability to override the Astro ON time with time-switch settings, thus further avoiding energy wastage.
 
With ever increasing pressures to reduce energy consumption, the Astro will control lighting, heating/cooling and humidity equipment in commercial, residential and industrial applications wherever sunrise and sunset times are critical in determining operational times, or where stipulated by local or national regulatory requirements.
 
The Astro’s micro-controller stores postcode data from 16 European countries, including the UK, which together with date information allows for the precise calculation of seasonal sunrise and sunset times. The Astro is also programmable using geographical coordinates, settable between 30°S and 64°N; 16°W and 50°E. The Astro will also automatically compensate, should European Summer Time be enabled.
 
For further versatility, the output switching can be advanced or retarded about the calculated sunrise (or sunset) time in 10-minute increments—up to a maximum of 90 minutes. A manual override of the output status allows for maintenance or one-off events.
 
With a 16 A 250 V AC rated output contact and a 120 A 5 ms peak current rating, the Astro time switch is capable of directly switching 2000 W halogen, 750 W compensated fluorescent, 200 W CFL or LED lamp loads and AC15 loads up to 750 VA.
 
The integral back-up battery, which is easily replaceable from the front, features an automatic power save mode which helps extend battery life.

Now the Eaton Moeller Series SmartWire-DT Is Smarter than Ever!

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.

FINDER New Generation of Staircase Timers Provide Extended Functionality for Energy Saving and Safety

 Finder.jpg

Finder announces a new generation of its 14 Series electronic staircase timers, which have been designed for energy saving control of lighting in areas of temporary occupation. The latest models feature microprocessor control, and are targeted at lighting applications in stairwells, corridors, washrooms, storerooms and similar areas that only require illumination for short periods of time.

Designers, contractors and installers of lighting in commercial and residential property are continually looking for ways to reduce energy consumption by eliminating wasteful lighting in unoccupied areas, while addressing the growing need to illuminate more public areas for security and safety reasons in an economical way. Staircase timers such as the 14 series offer a cost-effective solution that is simple to implement even in small installations.

FIN0044_14Series.jpg

The 14.01 timer is a multi-function unit, while the 14.71 is a single function version. Both models have an on period that is adjustable between 30s and 20 minutes, so that a single timer is suitable for wide range of installations. This flexibility of operation means that specification is simplified and inventory levels can be kept to a minimum. A further single function model, 14.81, offers wiring compatibility with earlier mechanical models.

All the new timers feature zero-crossing load switching, which enables the switching of higher lamp loads and also offers the benefits of longer lamp and unit life and reduced RF interference. A switch-off early warning function on the 14.01 gives a user who is still in the area time to re-activate the timer before the light is turned off.

Multi-function features on the 14.01, accessed via a simple rotary function selector, include timed control with or without manual override, early warning, standard on/off, permanent on and maintenance function with extended 60 minute on time.

Each timer can be used with up to 30 illuminated pushbutton actuators, offering local control over a wide area and thus giving the user maximum opportunity to re-activate the timer before being plunged into darkness: this enhances safety, and is especially beneficial in stairwells.

All the 14 Series timers are housed in a 35mm rail mounting enclosure that is 17.5mm wide, and have a timing adjustment suitable for standard consumer unit.
