CT/CR-7016     Contact Closure (16 Channels)    Front Panel Layout of CT/CR-7016
For Contact Closure or Status Monitoring Applications  

   Typical Aplication of the Contact Closer Monitor


The LiteLink CT/CR-7016 system consists of the CT-7016 transmitter and CR-7016 receiver. Both units utilize digital encoding techniques to transmit and receive eight separate contact closures over a single optical fiber conductor. For a lower cost single channel version see the CT/CR-7001, or 8 channel CT/CR-7008

The CT-7016 may be activated by dry contacts or TTL signals and the CR-7016 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. Integral indicators are provided on both units to continuously indicate the link and contact closures status as well as proper operating power thereby making system troubleshooting simple.
