(PL) Power Line Communications Option

(PL) Power Line Communications; Clock synchronization over the existing power line eliminates or greatly reduces the need for sync wiring. First, the master clock places the time onto the power grid. Then, all slave clocks receive the time from the power line. This means No New Wires. All digital clocks within a one mile diameter circle around the master clock will display the same time by simply communicating over existing power lines.

 The distance between the master and slave clocks may be up to 1,500 feet (500 meters), depending on line loading and other factors. Furthermore, slave clocks may be configured to repeat the time signal, for total range up to 3,000 feet (1,000 meters) between the master and slave clocks. This amounts to a communications area over one mile in diameter. Multiple master clocks may be used for greater range or when building power is supplied from multiple distribution transformers. The power line sync signal will not pass through power distribution transformers.

Two power line communication models are available. PL is for common, single phase power lines, and PL3 is for industrial, three phase power lines. The three phase model is only used on the master clock. The PL (single phase model) is used in most installations, including most three phase installations. Valid power options include P2 (110 volts AC), P3 (220 volts AC), P5 (100-240 volts AC), P8 (110 volts AC with 12' power cord) and P9 (110 volts AC with flat plug).

The master clock may optionally include a GPS or CDMA time receiver for the correct time, all the time. If no time receiver is used, the master clock can be manually set. For special applications, other options may also be used with power line communications including, serial wire sync, IRIG-B, SMPTE, midnight reset pulse sync, and more.

This option adds power line communications to digital clocks. When ordering, simply add the letters PL to the clock model number, i.e. BRG440-PL
