American Fibertek MT-81-280 8 Channel Contact Closure System, Non-Latching Relays, Multimode, Module Transmitter

The American Fibertek 81-280 Series multiplexes 8 channels of dry non-latching contact closure on one multimode fiber. Both normally open and normally closed outputs are available. A set of 8 LEDs on the transmitter and the receiver units indicates the channel(s) status.

Non-latching relay outputs will follow the state of the contact inputs under normal operating conditions. If either DC power or the optical power (connection) is lost, the relay outputs will switch to their normally open or closed states.

These systems require no field adjustments at installation or additional maintenance thereafter. Diagnostic indicators provide a quick visual indication of system status.
