The LuxLink™ CT/CR-7008 system consists of the CT-7008 transmitter
and CR-7008 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, for 16 channels see the
CT/CR-7016
The CT-7008 may be activated by dry contacts or TTL signals and the CR-7008
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. |
