Safely Transmit Critical Alarms over Fibre Optic Link
Omniflex is pleased to announce that the FCT & FCR modules have been successfully independently assessed by EI (Evaluation International) for use in Safety Integrity Level 1 & 2 applications.
Forming part of the extensive Omniterm range of Industrial Instrumentation equipment, the FCT and FCR modules are DIN Rail Mount Fibre Optic Contact Transmitters and Receivers designed for use in Safety Critical Applications.
The pair of modules provide the ability to send a digital contact signal up to 10km over a single optical fibre, making it ideal for monitoring of safety critical alarms.
The Relay contact input from the field is connected to the FCT module (Fibre Optic Contact Transmitter). This can be either Normally Open or Normally Closed (NC for fail safe operation). The state of this relay contact is then continuously transmitted to the FCR (Fibre Optic Contact Receiver) module over Fibre Optic cable.
In an Alarm condition, the relay contact at the FCR module will be energised or de-energised (fail safe), placing it's Changeover Contact output into the ALARM condition. LEDs are provided on each of the modules to display the state of both the input and output contacts and also the presence of instrument power.
