RTK SIL2 annunciator is certified to IEC61508

A RTK Instruments product story
Edited by the Engineeringtalk editorial team Jul 9, 2009

RTK Instruments is launching its SIL725 safety annunciator to provide high safety integrity for critical alarm applications and for use as a component part of a safety instrumented system.

The SIL725 annunciator is third-party certified by SIRA using the CASS methodology to a safety integrity level of SIL2 to IEC61508.

The unit uses RTK's multi-redundant design to ensure there is no single point of system failure.

The modular construction of the SIL725 Safety Annunciator allows units to be assembled in almost any size and shape to suit customer requirements.

Units can be constructed from a single alarm channel to a maximum of 128 channels, in any format, with ultra-bright LED illumination as standard and with a choice of two window sizes and six colours.

The unit can be panel or 19in rack mounted or fully integrated into a wall mounting or floor standing enclosure.

Each individual alarm way is fully configurable from the front, using the integral configuration module.

This allows the user to select many different features giving thousands of possible combinations.

This combination of user flexibility and SIL2 certification is a feature that is said to be valuable to all those involved in instrumentation for the process industry.

The SIL725 annunciator has common safety related relay outputs that are SIL2 compliant.

These can be used as part of a safety instrumented system.

Each annunciator can have up to two Horn relays and two Group relays and each alarm channel can be configured to drive any of these common relays.

RTK Instruments is a supplier of alarm annunciators and systems, event recorders and hazardous area notification equipment.

RTK can also offer design, supply and commissioning of custom systems through its Engineering Solutions service.
