　　特色应用
　　在光纤布线的IRIG-B码转换解调IRIG-B从时钟′的DB-9或BNC端口（使用适配器电缆）成纤维sel-3405t，sel-3405r接受IRIG-B通过光纤端口和输出到DB-9或BNC端口（使用适配器电缆）。
　　B从远程时钟把时间从远程卫星时钟进入控制室。这是特别有用的，在安装天线的位置是不可行的，因为一个明确的看法的天空是不可用。把你的天线和时钟，它可以得到一个好的卫星信号，并发送小于200 ns的精确解调码到使用sel-3405需要。
　　IRIG-B码的变电站的院子里送的高精度解调装置在变电站的IRIG-B码同步，IEC 61850-9-2采样值，或其他高精度授时应用。配置三sel-3405r接收器在一圈送< 1?的IRIG-B码到多个设备。
　　适配器电缆
　　这是任何sel-3405 SEL时钟兼容。使用sel-c940 DB-9双插头电缆将设备连接到一个sel-3400 IRIG-B码分配模块。使用一个BNC连接到sel-3400和权力的sel-3405另提供时间。使用sel-c942 DB-9 BNC公镀锡铜线电缆电力设备使用sel-9321电源。使用BNC连接到输入结束时间装置或从时钟接收时间，并使用镀锡电源线

　　FEATURED APPLICATIONS
　　IRIG-B Over Fiber-Optic Cabling—Convert demodulated IRIG-B from a clock′s DB-9 or BNC port (using adapter cable) into fiber using the SEL-3405T. The SEL-3405R accepts IRIG-B via its fiber ports and outputs it to a DB-9 or BNC port (using adapter cable).
　　IRIG-B From a Remote Clock—Bring time from a remote salite clock into the control house. This is especially useful in locations where installing an antenna is not feasible because a clear view of the sky is not available. Place your antenna and clock where it can get a good salite signal, and send <200 ns accurate demodulated IRIG-B to where it is needed using the SEL-3405.
　　IRIG-B to the Substation Yard—Send high-accuracy, demodulated IRIG-B to devices in the substation yard for synchrophasors, IEC 61850-9-2 sampled values, or other high-accuracy timing applications. Configure up to three SEL-3405R Receivers in a ring to send < 1 ?s IRIG-B to multiple devices.
　　ADAPTER CABLES
　　The SEL-3405 is compatible with any SEL clock. Use the SEL-C940 DB-9 to Dual BNC Male Cable to connect the device to an SEL-3400 IRIG-B Distribution Module. Use one BNC connection to provide time to the SEL-3400 and the other to power the SEL-3405. Use the SEL-C942 DB-9 to BNC Male to Tinned Wires Cable to power the device using an SEL-9321 Power Supply. Use the BNC connection to input time to the end device or to receive time from a clock, and use the tinned wires for power.
