Finder Introduces Meters for Individual Monitoring of Energy Consumption

 Finder.jpg

The 7E Series single phase kWh totalising meters from Finder have been designed for the measurement, recording and display of individual energy consumption for loads drawing up to a maximum of 65A.

 FIN0033_7ESeries.jpg

 

The meters are targeted at applications in residential, commercial and industrial  installations where the consumption of energy needs to be measured or monitored.  This might be either to assist in meeting government targets for reduced emissions by minimising energy consumption, or to allow metering of locally billed electricity supplies. Typical areas of use might include test laboratories, the individual monitoring of machines, control cabinets and switchboards, in battery charging equipment, or for hook-up supplies to campers, caravans and boats.

The meters can be DIN rail mounted, and can easily be installed in a standard consumer unit. A high resolution pulsed open-collector output allows accurate remote monitoring.

The two models in the series, the 7E.13 and 7E.16, are rated for maximum current levels of 32A and 65A respectively, for a supply voltage of 230V AC at 50Hz. The display counter features a 4mm high, 7-digit display with a red decimal digit, giving a maximum totalising count of 999,999.9kWh. Both models have a maximum resolution of 100Wh, and their accuracy is specified as Class 1 (±1%). Rated power is 8VA and the AC operating range is 0.8 – 1.15 of nominal voltage.

The meters are housed in compact industry-standard packages with simple direct wiring connections. They are PTB approved in accordance with EN 61036, and carry CE type approval for EMC.

Model 7E.13 is a single unit width (17.5mm) with the digits arranged vertically, while 7E.16 is double unit width (35mm) and has a horizontal digital display. Both models feature a flashing red LED as a quick visual indication of operational status.

Finder Miniature Time Delay Modules for Relays

 Finder.jpg

The Finder 86 series miniature plug-in time delay modules can be used with a wide range of Finder rail-mounted relay socket combinations including the latest 46 Series Industrial Relays. The timer modules in the 86 series are among the smallest and most versatile currently available.

 FIN0032_timer_modules.jpg

The modules offer the ability to introduce a time delay to the operation of relays, and are ideally suited for use with control circuits that require a delayed relay response in order to ensure the correct functioning of logic or sequence. The timer modules can either be fitted during panel assembly or retrofitted without any need for re-wiring or for the introduction of components requiring additional panel space.

The time delay modules are compatible with sockets having both screw and screwless connection formats, and can be used with relays from Finder’s 40, 44, 46, 55, 60 and 62 series, therefore providing the facility for multiple delayed contact combinations from 1 CO to 4 CO with switched current ratings from 7A to 16A at 250V AC or 30VDC.

ON delay and ON pulse functions, four time delay ranges spanning 1.5s to 64 min and a 12 – 24V AC or DC operating voltage mean that fewer models need to be held in stock to cover the whole range of available specifications.

By ensuring that all future introductions of relay socket combinations offer full compatibility with the 86 series, Finder guarantees the user continued maximum flexibility of operation for the widest variety of applications.

Finder Rail Mounting Sockets Feature Screwless Terminations

 Finder.jpg

New from Finder is a range of 35mm rail mounting sockets featuring screwless terminations. Designed for use with Finder’s 34, 40, 41, 44 and 55 series plug-in relays and 85 series timers, the sockets can be used in any application where power and control wiring is terminated. The sockets will allow panel builders, machine builders, system integrators, OEMs and installers to make a reliable and vibration-resistant connection to the relay or timer in the shortest possible time.

 FIN0031.jpg

 

Conventional screw terminals must be tightened to a specified torque during assembly: this process is time-consuming, and it is difficult to ensure that it has been performed correctly. As a consequence, screw connections can work loose under high levels of vibration, either in operation or when being transported. Screwless connections are achieved by means of two metallic blades that are both under tension, which will always force a strong closing action on the wire.

The sockets are all suitable for 35mm rail (EN 50022) mounting and, depending upon type, may also be suitable for panel mounting. The sockets offer the same features and performance as their screw terminal equivalents, allowing the designer the choice of a screwless termination without compromising on other parameters.   Many of the sockets accept Finder’s range of coil indication, EMC suppression and timer modules, and all feature plastic retaining and release clips .

The wide range of relay socket styles that are now available in the screwless format means that the benefits of reduced wiring time and termination reliability can be offered across a large selection of Finder’s relay types and ratings.

These sockets are the result of Finder’s total in-house capability for product design and expertise in advanced manufacturing technology; encompassing the design and manufacture of all precision mould and press tools, automated assembly machinery and test equipment.

Finder Miniature Single-Pole and Two-Pole Relays Offer Terminal Compatibility With Industry Standard

 Finder.jpg

New from Finder is the 46 Series miniature industrial relay range. The 46 Series has evolved from the successful PCB mount 40 Series, and provides both single-pole and two-pole contact configurations for use in control panels and systems. The key characteristic of this new range is its full terminal compatibility with a widely used but single sourced de-facto industry standard. The Faston spade/blade terminals provide secure and reliable connections between the relay and the associated 97 Series socket, over and above that achieved by its predecessor.

 FIN0030_46series.jpg

Says Finder’s Sales Manager Ted Waller, “This type of relay with spade terminals has been primarily single-sourced until now. The introduction of the 46 Series provides the customer with a real choice, offering a higher current rating than the competing product, and a unique range of optional plug-in modules for greater functionality that is not available elsewhere”

The 46 Series relays are available with either AC or DC coils, and benefit from a host of advanced features and options, including a mechanical flag indicator and manual test button that can be used in momentary or latching mode – useful during commissioning, fault tracing and override situations.  A version with LED indication is also available.

The 46.52 relay has a two-pole changeover (DPDT) configuration and a maximum rated current of 8A, while the single-pole changeover (SPDT) 46.61 model is rated at 16A maximum.

The associated 97 Series rail mounted sockets feature a flip-out retaining and release clip for easy removal of the relay. Uniquely these sockets accept an extensive range of time-delay, coil indication and EMC suppression modules and an 8-way jumper link that reduces the time taken to wire common connections.

As an alternative to using the rail mounting socket the relay can be secured by an optional flange-mount bracket allowing direct mating with Faston connectors.

The terminal arrangement and pitch of the 46 Series are fully compliant with existing relays of this type, and the new relays can be used as a drop-in replacement for industry standard products.
