3.2 WIRING 3 HARDWARE
The IRIG-B repeater provides an amplified DC-shift IRIG-B signal to other equipment. By using one IRIG-B serial connec-
tion, several UR-series relays can be synchronized. The IRIG-B repeater has a bypass function to maintain the time signal
even when a relay in the series is powered down.
