The S.I.Tech Model 2811 TR transmits a 10 KHz optical square wave over fiber optic cable when power is applied and the control input is shorted. It operates at 820 nm wavelength with an optical power budget of 10 dB and supports ST or optional SMA fiber connectors. Power input is +12 VDC or +24 VDC at 50 mA. The unit has a plastic enclosure measuring 6" X 6.5" X 2.75" (15.2 X 16.5 X 7 cm) and operates from 0°C to 50°C. It meets FCC Class A, Part 15 requirements. Indicator LEDs for power and carrier detection are on the front panel.
The S.I.Tech Model 2811 TR transmits a 10 KHz optical square wave over optic fiber when power is applied and control input shorted. The 2812 receiver detects this optical square wave and turns ON a 4PDT relay. If the fiber cable is removed, broken, or the remote transmitter or local receiver loses power, the relay in the local receiver will turn OFF. The 4 sets of Form C (4PDT) relay contacts are provided on the rear panel via screw terminal blocks. The power input (+12 VDC or +24VDC is also via screw terminals. The fiber optic input/output is provided on the rear panel via ST recepta 905/906 compatible SMA receptacles are available as an option. The front panel contains 2 indicator LEDs, a power ON indicator and a CARRIER (10 KHz detected) indicator.
