Applied Relay Testing Ltd is an SME, formed in 1992 in response to a small but significant niche market requirement for turn-key relay test equipment. Using our products, relay devices can be tested in both production and laboratory environments, with the benefit of standard test methods and well developed software facilities. The objective of the application experiment was to produce new test circuitry suitable for incorporation within a new parametric relay test system product, the RT290, enhancing technology in three general areas as follows:

  • Replacement of mechanical relays by new-generation MOS devices.
  • Upgrading existing 74-series logic circuitry to higher density programmable logic devices.
  • Use of DSP techniques within the test system.

This new technology has allowed us to offer, at a given price, shorter test times, higher reliability, and the flexibility to adapt to individual customer's needs. This has increased the cost benefit of our product, making it more attractive for inclusion in highly automated systems. We are now actively planning new markets in Japan and the USA where a high-quality, high-specification product is expected to appeal greatly to prospective customers.

Following completion of the experiment, it was clear that the originally perceived risks of introducing the new technology were much greater than in reality. This was due to natural caution and ‘fear of the unknown’. However, with good advice, guidance and the adoption of a planned approach to the project, these perceived risks were quickly replaced by expectations of success.

The costs of the experiment were 29KECU, and the project took 9 months. These costs will be recovered within 16 months and the Return on Investment during the life if the product is anticipated as being in excess of 200%.

Detailed information

You can also benefit from microelectronics

FPGA and DSP- technology provided Applied Relay Testing Ltd with the means of improving its products and enhancing its market position. You can also achieve significant benefits by acquiring the right microelectronics technology and utilising it in your product or manufacturing process. You can get help from FUSE to realise this.

FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.

FUSE provides you with:

  • Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
  • Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
