The cards are engineered to provide backup reliability in a compact, easy-to-use, and
economical package. When inserted in the PCO- 818 frame, their advanced modular design
provides a level of flexibility never before available in an Automatic Changeover unit. When
combined with it’s sync generator companion (the SPG-812), the PCO-818 frame offers the
best performance and reliability available today. Their modular design offers several
advantages over traditional automatic changeover units. Monitor only the signals
used by the system: no need to pay for monitoring capability that is not required by
the system. Install only the modules you need now, and add more later.
Since the PCO-818 frame and the SPG-812 frame share a common chassis, modules
may be interchanged between units. It also allows us to mix analog and digital signal
monitoring in the same chassis. For example, a television station may use a SPG-812
primary module, backup module, and changeover module,all installed in either chassis. In addition, they are designed such
that AC mains failure will not erase the memory of their last generator selection. A dual-coil latching relay provides areliable
signal path even if power is lost to the 818-OP/PL. Meanwhile, its power supply features a “universal” voltage input range of
85VAC to 260VAC. In extreme conditions, the modules would be the last unit to shut down in the event of an AC mains failure.
Bi-color LEDs provide instant status indication for each signal in your system. If a particular signal is not in use, the LED can
be easily de-selected (dark) rather than produce a false failure (red) indication. A “Manual/Automatic” switch allows the user
to over-ride the automatic changeover function and select either generator in the system. As your system grows and new
technology arrives, the PCO-818 series of modules stands ready to grow with
you.
818-OP/PL
Pulse Auto Change-Over Unit
The basic function of the 818-OP/PL is to
monitor an installation’s analog pulse and
automatically switch to a backup analog
pulse in the event of a failure.
