Sick ReLy safety relays offer faster response and longer lifeWhen it comes to safety relays, small performance improvements can result in big productivity gains. That is why Sick is launching its ReLy safety relays that achieve a 10ms response time and provide a class-leading, long and durable product lifecycle.

Just four Sick ReLy safety relays meet most needs for monitoring safety functions or safety sensors up to PL e (EN ISO 13849) and SIL3 (IEC 61508), while enabling simpler selection, installation and maintenance.

Seb Strutt, Sick UK's safety specialist, explains: "Safety relays may be an everyday device for monitoring safety sensors and switches, but identifying the best-performing product for your application can be a time-consuming and laborious process. With such a plethora of different devices on the market, we wanted to rationalise safety relay specification.

"Sick's ReLy safety relays therefore offer some great 'new tricks' from an old friend. Our aim was to achieve true gains in performance and usability while making it easier for engineers to stay with a high-performing range they can rely on, saving them selection time and reducing stock inventories."

The Sick ReLy safety relay more than halves the response time of comparable safety relays, thereby reducing corresponding safety distances. Even a small reduction in safety distances can result in a significant overall increase in operator productivity on a machine.

Easy installation and maintenance

The ReLy's narrow 18mm-wide housing takes up minimal space in control cabinets, with easy push-in front wiring and a one-click fit-and-release mechanism for simple set-up and quick replacement.

A 'reset-required' output to the ReLy relays and on-board diagnostics via an LED status display enables easy maintenance with minimal downtime. The Sick ReLy is also capable of operating for a class-leading number of switching cycles before replacement is needed.

Just four products make up the ReLy family:

  • ReLy OSSD1 - for sensors with OSSD outputs and integrated reset/EDM functions, and therefore particularly suitable for use with advanced AOPD devices such as scanners and advanced light curtains.
  • ReLy OSSD2 - includes input and output reset buttons with flashing LEDs for sensors with OSSD outputs but without reset/EDM functions such as simpler light curtain units, sensors and door interlocks.
  • ReLy EMSS1 - provides an option for mechanical switches such as emergency stops and door switches.
  • ReLy HAND1 - for use with two-hand control devices as per EN 574.
