The CT-7001 may be activated by dry contacts or TTL signals and the CR-7001
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.
