SEL's Fiber-Optic V-Pin Transceiver


The SEL-2820 Fiber-Optic V-Pin Transceiver allows instrumentation and control professionals to safely add isolated segments to multidrop and point-to-point EIA-485 networks separated by up to 500 meters. It also connects segments with optical fiber instead of copper wire, improving safety, signal integrity and reliability. The SEL-2820 is easy to integrate. The transceiver operates over a –40° to +85°C temperature range and meets or surpasses electric utility and industrial type-test standards for instrumentation, control, and communications equipment.
