Model 10889A Fiber-Optic to Logic Adapter - 6 Outputs

The Model 10889A Fiber-Optic to Logic Adapter converts signals received via optical fiber into CMOS levels. The received signal is distributed to six individually-buffered outputs, each using a two-pin connector. Mating connectors are supplied with the unit.

The outputs deliver 0 to 5-volt logic signals, with a high output corresponding to fiber illumination. A green light emitting diode is lighted whenever the output levels are high.

The 10889A is powered by an external 9.0V to 13.5V DC source. With all outputs fully loaded, the input current required will be less than 250mA. A second green LED indicates that power is supplied to the unit. Power is supplied via a two-pin header, with included mating connector. The input is protected against reverse polarity.
