3.3.4 Triggers in/out BNC connectors (panic, arm, and sag)
On the upper left corner of the rear panel there are three BNC
connectors.
These are 0V min, 24V max signals. Do not connect other
voltages to these connectors. The shield side of these BNC connectors
in connected to the chassis.
You can use the signals on the ARM and TRIGGER BNC connectors
to trigger external data acquisition - the
ARM signal will go low
approximately 2 cycles before the event begins, and the TRIGGER
signal will go low exactly as the event begins.
You can use the PANIC BNC to provide a remote trip switch for the
main circuit breaker
. Simply shorting across the PANIC BNC will
assert the internal Panic signal, which will shunt-trip the breaker.
(These BNC connectors also play a role in a future option that
allows multiple IPC’s to work together.)
3.3.5 RJ-45 rear panel communications ports
To the right of the BNC connectors on the upper left of the rear
panel, there is a row of 6 RJ-45 connectors.
These connectors are all
reserved for future expansion capabilities.
3.3.6 Analog outputs
On the upper right area of the rear panel, find a row of 9 BNC
connectors.
These are all ±10-volt scaled analog outputs of the internal voltage
and current readings, on the load side of the IPC.
These signals are
digitized and stored by your IPCs' data acquisition system, but having
them available as outputs offers a convenient means of reading the data
on an oscilloscope, chart recorder, etc.
The signals include both phase-to-neutral and phase-to-phase
voltages, scaled at 1 volt out = 100 volts in .
The three current outputs
are scaled at 1 volt out = 100 amps in.
The shield side of these BNC connectors in connected to chassis,
and there is a 5 kiloHertz low-pass filter on the signals.
The source
impedance of the signals is approximately 1k ohm.
