Dry contact closure input
. Applying
a voltage to these pins may damage
the unit.
When linked to a FVT109A
, the output
relay refl ects the state of the input
contact (open or closed).
When linked
to a FVT109A-M
, the output relay
indicates the state of the optical link.
The terminal pair is closed when the
optical port has established link, and is
open when the optical port has lost link.
NOTE: It is possible to configure the FVR109A output relay to indicate the link status instead of
the contact closure input when linked to a FVT109A. Consult the factory for more information.
