Distribute IRIG-B time to SEL products and other devices, and connect GPS and radio antennas to SEL devices with an antenna connection.
Communicate up to 500 meters with port powered fiber-optic transceivers
Communicate up to 4 kilometers with port powered fiber-optic transceivers
Isolate EIA-232 and IRIG-B signal lines to reduce signal-ground current induced by adjacent high-current conductors.
The SEL-3400 is an inexpensive, reliable, and precise way to distribute demodulated IRIG-B time information. With twelve IRIG-B distribution ports and a bright display, the SEL-3400 is ideal for time distribution in panels.
High-visibility digital clock display synchronized by IRIG-B time signal may be connected together to make synchronized clock system.
Send delay-compensated demodulated IRIG-B up to 4 km over fiber-optic cable with SEL-3405 High-Accuracy IRIG-B Fiber-Optic Transceivers.
Use one pair of fibers for full-duplex serial communications plus IRIG-B time synchronization.
