AFI MR-88 1310nm 12dB MM Eight Supervised Contact Module Receiver

Eight Supervised Contact Module Rx 1310nm 12dB MM.

The American Fibertek MR-88 multiplexes 8 channels of “supervised input” dry contact closure on one multimode fiber. A set of 8 LEDs on the transmitter and the receiver units indicates the channel(s) status. The Contact Input supervision will detect an open connection and a shorted connection as an alarm. The alarm condition is removed only when the Contact Input voltage falls within a predetermined range. Failsafe operation is provided such that, if the optical power is loss or the transmitter or receiver dc power is loss, the normally open contact outputs will go to the alarm states (open). 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 American Fibertek Card Cages: SR-20/2 or SR-20H/2 (redundant power supply).

• 8 Channels, Form-C (Normally Open or Normally Closed) Dry Contact Closure
• Diagnostics: Power, Optical Presence and Channel Indicators
• High Density DB26 Data Connector with Adaptor to screw terminal
• External Contact Input Supervision
