Switching of three-phase motors or a realization of a sophisticated installation is a breeze with industrial relays Finder.

As we know, a relay is a very versatile component, able to realize also various “sequential” circuits, when for example by switching one relay we´ll switch on a target device and at the same time we´ll enable (or disable) switching of another relay. In these case, it´s an often demand for a relay to have a sufficient number of poles. Majority of such “logic” circuits can be realized even with a common 1-2 pole relays, but it´s not always economical and it also brings another costs for solution of supplying and protection of logic circuits.

Industrial relays Finder series “55” and “60” are suitable for a construction of such more complex circuits or for switching of three phase devices.

  • Finder 55 – miniature industrial relay for a PCB or for socket, 2-4 poles, 7-10A (switching current up to 20A), 250/400VAC,
  • Finder 60 – a more robust industrial relay for a socket, 2-3 poles, 10A (switching current up to 20A), 250/400VAC,

In the series 55 can be found types which can be soldered directly into a PCB (without a socket) or to insert into some of many available sockets (for PCB, with soldering pins or on a DIN rail). Types from series 60 need to be inserted into a socket (for PCB, with soldering pins or on a DIN rail). Naturally, for eventual repair/maintanance, it´s much better to use a socket. Sockets can be equipped with metal or a plastic clip. Also exists a socket 94.94.3 with a safety separation of an input and output part. Similarly like at majority of Finder types, sockets can be equipped with optional protection and indication modules. Read the rest of this entry »

In our portfolio you can also find a DIN rail socket for the ultra slim relay Finder 34 series. It enables to use various relays thus to simply adapt an interface module to a given application.

From nowadays offer of relay interface modules, it is already no problem to choose a type meeting requirements of a given application. But if you need to change a configuration of a device, it is often convenient to change only a relay type. Series 93.01 socket enables this easily, because the protection and indication circuit is designed for a wider range of input voltages. This enables to use a 5V, 12V and 24V Finder relays 34.51 series. A green indication diode indicates presence of a control voltage and the protection circuit protects relay against reverse voltage and suppresses voltage spikes appearing at its switching off. When using 93 series socket, it is even possible to use an AC voltage to supply a DC coil of a relay.

Finder 34 series relays are ultra slim 6A relays with a sensitive DC coil. High 6kV isolation provides a safe disjunction of relay coil from contacts. Finder 34.x can be mounted directly to a PCB, via a PCB socket or to a DIN rail by means of the above mentioned socket. In some applications can also be convenient relatively short switching times – 5/3 ms.

Phoenix DIN-rail enclosures meet the most stringent criteria and offer a wide variability of PCB placing.

Top quality is a main advantage of Phoenix Contact products. With over 80-year tradition and 11000 employees belongs Phoenix Contact among leading producers of electric contacts and industrial automation technologies. In a portfolio of Phoenix Contact products we can find products covering almost all industrial segments.

Modular DIN rail enclosures have earned a big popularity. From many available types we added to our offer ME a BC series. They offer a very quick and simple assembly of devices into the enclosure and a big variability. Both series can be equipped with a bus and connectors, what enables a simple interconnection of enclosures between each other, connection of power supply, data transmission etc. ME series enclosures are made of polyamide, BC series enclosures are made of polycarbonate and both materials meet UL 94-V0 – self-extinguishing.

Detailed information will provide you the overview of Phoenix BC and Phoenix ME series.

With a powerful relay interface module Finder 48 series you can control devices reliably and digestedly directly from a distribution box.

Very often used centralized control of devices from a distribution box via relay interface modules offers several benefits. This solution enables for example a transparent and quick installation, simple functionality test and easy changes in configuration if necessary. To place switching elements to a DIN rail can in many cases substantially increase the immunity to disturbances. It is thanks to the fact, that when a relay interface module is placed in a distribution box near a controlling electronics, wires leading to the module are very short. By this we avoid parallel layout of control wires with other power-line wires, often few tens of meters long, from which a current able to switch on a relay could be inducted in extreme cases.

Advantages / Features:

  1. relay interface module for a DIN rail
  2. versions with 1 or 2 changeover contacts
  3. 8/16A 250V AC rated current
  4. 10*10E6 mechanical life
  5. ambient temperature range -40 to +70°C
  6. only 0.5W power consumption (DC versions)
  7. contains components for EMC coil suppression and indication status LED
  8. made in EU

Finder 48 are powerful relay interface modules in versions with one or two changeover contacts. They are available with a coil for DC or AC voltage as well as with screw or screwless terminals. From our stock we offer you 2 versions – 48.52 and 48.61 with a sensitive DC coil with only a 0.5 W power consumption. Interface modules already contain components protecting against wrong voltage polarity, for EMC suppression as well as indication circuit with a LED.

Besides high 16/8A switching currents offer Finder 48 also a high level of safety thanks to an up to 6 kV insulation voltage (coil/contacts). Finder 48 enable instant relay rejection by means of a plastic retaining clip, what makes an inspection or exchange of a relay easier. Also available is the jumper link for a mutual interconnection of several interface modules. Detailed information will provide you the Finder 48 datasheet.
