Relays

What is a Relay?

Relays are electrically operated switches that open and close circuits receiving electrical signals from external sources. The relays built into electrical products work in a similar way; they receive an electrical signal and send the signal to other equipment by turning the switch on and off. The three main functions of relays are to allow a small amount of electrical current to control high current loads, send different types of electrical signals, and drive multiple outputs with just one input.

What Do We Supply?

We have a broad range of relays in stock, including:
Modular step relays
Monostable relays
Ultra-slim PCB relays
Relay interface modules
Miniature PCB/plug-in relays
Low profile PCB relays
Miniature industrial relays
Safety relays
Power relays
Miniature power relays
Solid State relays
Relay bases
Coil indication
EMC protection

Why Choose E. Preston?

We are an official distributor and wholesaler of relays from brands such as Crouzet, Crydom and Finder. These are well known companies in their fields with excellent reputations for the quality of their products.

What really sets us aside from our competition is our choice and range of relays – you really don’t need to look anywhere else for your requirements.

As we have been operating for over forty years, we have developed a fantastic relationship with our suppliers. This benefits us in two main ways: We gain access to the widest choice of components from those suppliers, and secondly, they sell us those components at competitive prices because we purchase such significant volumes. We are able to pass on those competitive prices to you, our customer.

We have a large stockholding of our products at our warehouse in Dukinfield, Cheshire in the UK. This stock means that our product availability is consistently high, and we can get your order for stock items out to you in a 24 to 48 hour time frame.
and we can talk through your specific relay requirements.

PLN6 xPole Miniature Circuit Breaker

Pln6

The PLN6 miniature circuit breaker (MCB) is a protective device that’s equipped with both a thermal and an electromagnetic release. The former responds in the event of an overload, while the latter offers protection against short circuits. The 1+N-pole MCB is only 1 HP wide and is available with rated currents from 2 A to 40 A. The switching capacity is 6 kA.

The circuit breaker, which is available with tripping characteristics B and C, is equipped with a red-green contact-position indicator for indicating the device state: green means that the contacts are open, and red that they are closed.

SCS200 – Intelligent Power Management

Intelligent and complex systems as well as the electrification of loads currently play a decisive role in the development of on-board electrical systems.

The SCS200 is the right answer to these requirements. It is an intelligent power distribution system, enabling decentralised control and monitoring of loads via CAN bus. The design features a PCB-based power distribution in a compact IP66/67 enclosure.

The SCS200 modules are plug & play solutions which help reduce wiring time and space requirements. Its comprehensive diagnosis capability (integral load protection, load current and voltage measuring, output status) and its integral CAN connection enable predictive maintenance and implemented load management.

Typical Applications:

  • Agricultural machinery, construction machinery, special vehicles, trucks and buses
  • Decentralised power distribution downstream the ECU
  • Vehicle modernisation and easy system extension through standardised CAN components

Benefits

  • Predictive maintenance and load management through comprehensive diagnostic functions (current, voltage, status)
  • Facilitated wiring through plug & play solution with CAN connection
  • Space-saving, flexible installation through compact IP66/67 housing
  • Increased safety through integral electronic load protection
