Omniflex can provide plants with a complete site-wide alarm-management system in accordance with the requirements of the IEC61508 and EEMUA 191 standards.

Ideal for areas of high electrical interference, these systems include the conditioning of the front-end process signal through SIL-rated trip amplifiers and transmit these alarms over copper cable or via SIL2-rated fibre-optic transmitters/receivers (where fibre-optic cable is used) into SIL-rated alarm annunciators and sub-1msec sequence-of-event recorders.

The Omniterm fibre-optic transmitter/receiver modules (FCT and FCR) provide the ability to send a digital contact signal up to 4km over a single optical fibre.

The FCT and FCR modules have a PFD that is suitable for SIL2 (Safety Integrity Level 2) applications.

The Omniterm FCT and FCR are designed to be DIN-rail or surface mounted and are 22.5mm wide.

Features: high data rate and wide bandwidth; immunity to EMI/RFI and lightning damage; no ground loops; low attenuation (data loss); longer distances; secure communications; low system cost; and longer life expectancy than copper or coaxial cable.

The Omniflex safety-critical Alarm Monitoring System helps customers to protect their plants and personnel, and enables compliance with HSE and safety regulations.

The company was founded in 1965, formerly known as Conlog, specialising in process control, alarm/event management and instrumentation products and systems. In 1997, the original instrumentation business division of the company changed its name to OMNIFLEX Ltd.

Omniflex works across all business sectors including pharmaceuticals, hospitals, oil, gas, nuclear, water, electrical distribution and energy monitoring.

The company has its offices in the UK, South Africa, and Australia, and the company’s products are sold on five continents. Product ranges include well-known brands such as OMNI SIL alarm annunciators, OMNITERM SIL signal conditioning, MAXIFLEX intelligent remote terminal units (RTU) and I/O systems and the MAXILARM/Omni 4000 alarm/event management systems.

We bracket ourselves as a ‘remote monitoring specialist’, using data acquisition systems, with better than 1mS timestamp at the IO point (from several I/O up to thousands of I/O),  alarm event management including multiplexing systems, telemetry systems, Data2Desktop using standard web browsers, over varying forms of media and high-integrity (SIL1) annunciator systems.

A particular area that Omniflex is also very strong in is obsolescence issues on old legacy alarm annunciators systems. We have, in most cases, a solution for replacement of Rochester, Highland and Robinson’s annunciator systems. Our alarm annunciator systems have been substantiated by Sellafield for and on behalf of all the nuclear operators.

An area that we can offer customers significant cost savings is through the use of our CONET networking technology, which is supported by many of our RTU / PLC products. Using our CONET network technology allows existing installed cabling to be used therefore significant cabling/installation costs can be avoided. A typical example of this whereby our customer in the nuclear industry used our CONET technology, retained their existing cabling and infrastructure, saved them in the region of £1m on cabling and scaffolding.

As a worldwide supplier, OMNIFLEX provides technical training, back-up and application engineering support to a variety of industry partners including local distributors, value-adding resellers and systems integrators, to provide superior levels of service to the end user.
