PTC901 Application

A big application request has always been for
Real-Time Clocks to display time throughout the
plant. The challenge has been to keep all the
various clock locations synchronized with the
right time. With the new PTC901 Timer/Real-
Time Clock this problem is history. You can install
up to a maximum of 32 units. Simply select one of
the units in the system as the host and the balance
are programmed as slaves. The host will send out
a synchronization pulse every hour to correct the
time on any clock unit wired in the system.
