For Contact Closure or Status Monitoring Applications  

   Fiber Optic Contact Closure Transmitter Application

The Luxlink CT/CR-8001 system consists of the CT-8001 transmitter and CR-8001 receiver. Both units utilize digital encoding techniques to transmit and receive one contact closure over a single optical fiber conductor.  For an 8- channel version see the CT/CR-7008.

The CT-8001 may be activated by dry contacts or TTL signals and the CR-8001 will reproduce these inputs as isolated output contact closures corresponding to the respective input signal. All inputs are transient protected against excessive surges present on the signal and power leads. The unit is completely fail-safe in that a loss of operating power or a broken fiber will force all contacts to the open condition.
