Eight or Sixteen Channel Contact Closure System
With Power Fail Safe Normally Open / Normally Closed Outputs
The American Fibertek 81 Series multiplexes 8 channels of dry latching
contact closure on one multimode fiber. The American Fibertek 82 Series
multiplexes 16 channels of dry latching contact closure on one multimode
fiber. A user-selectable feature allows the contact status to be maintained
unchanged or reset through power-cycle and loss-of-optical-power. A reset
button is available to clear all contact status to the default state. Individual
channel LEDs on the transmitter and the receiver units indicate the channel
status. These systems require no field adjustments at installation or additional
maintenance thereafter. Diagnostic indicators provide a quick visual indication
of system status. Equipment may be ordered as stand alone modules or rack
cards that are mounted in the SR-20D/2 or SR-20R/1 AFI Card Cages.
The
“Afinety” intelligent remote monitoring system is available on the Rack Card
product, please consult factory.
