Description
Use this signal to supply 15 V dc; it will
source a maximum of 100 mA.
This signal is a dedicated return to
internal system ground, then to chassis
ground, and finally to protective earth-
ground.
We recommend that all signals in the
interlock string be referenced to this pin.
This 0 to 15 V signal is held low for 10
to 20 ms whenever an arc is detected at
the MDXII output.
It will sink 35 mA. It is internally pulled
up to 15 V through a 10-k
Ω
its impedance is 100 .
This 0 to 15 V signal goes low when the
target-life counter reaches zero, thus
indicating that target life has ended
("end of target life").
This signal will sink 35 mA. It is
internally pulled up to 15 V through a
Ω
10-k resistor, and its impedance is
Ω
100 .
This signal provides a fully buffered
signal, representing output voltage. Its
Ω
impedance is 100 . It will sink and
source 50 mA.
See Table 9-2 on page 9-15 for the
standard analog signal scalings.
