SEL-2894 Интерфэйс хөрвүүлэгч

Transfer SEL Mirrored Bits communications via an IEEE C37.94 fiber-optic link through a communications multiplexer. Or, convert other EIA-232 serial links to IEEE C37.94 optical fiber links for improved safety, signal integrity, and longer distances.

High-Speed Communications
The SEL-2894 has very low latency adding only 375 µs of through delay back-to-back. It works with EIA-232 signals from 300 bps to 19,200 bps.

Three LED Indicators
TX and RX green LEDs show incoming and outgoing fiber-optic states. A standard yellow alarm LED indicates a transmission problem.

Selectable Time Reference
A side-selector switch on the SEL-2894 configures the internal clock for either external or internal time reference.

Flexible Power Supply
The converter connects directly to a standard 9-pin serial port and receives power directly on Pin 1 so no external power is required when used with SEL relays. The converter can also receive power from an external supply when connected to other devices.
