Omniflex offers alarm-management system for plants
Omniflex
Omniterm Alarm Monitoring System
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.
