Omniflex are satisfying customers requirements for high, single loop, integrity contact repeaters over fibre-optic cable (single-mode or mult-mode) using their latest Fibre-optic Transmitter and Receiver modules.
The Din Rail Mount Fibre-optic Transmitters and Receivers enable you to send a single digital contact over a fibre-optic link (volt free input, Form C output) over distances up to 10KM.
The units are 10-30Vdc powered and have a high reliability circuit with published MTBF and PFD figures with fail-safe operation.
In many applications these units are being used to acquire critical alarm data within the nuclear and commercial environments.
In one particular application in the nuclear industry, 64 critical alarm were acquired, together with other data, using a site-wide blown fibre network. A single fibre was used for each channel with up to twelve fibres in each tube. The basic fibres were terminated in "patch" enclosures then ST Patch-fibres were used for the final connections. This approach enabled installation tasks to be logically split and greatly expedited commissioning of the complete system. LED's on the front of the Fibre-optic transmitters and receivers indicate the presence of power and the status of the input/output, further assisting rapid commissioning. The individual volt-free contact outputs were connected (fail safe) to an Omniflex Omni16C SIL 1 Alarm Annunciator System. Individual repeats were then wired to a Maxiflex Data Acquisition systems for archiving.
