[AUX +, -] [power supply available via self-restoring fuse
protected output F5 .
[U1] programmable positive output protected by 100 ohm
resistor (ON=13 .8 V DC, OFF=NA) .
[U2] for the PXC200 it's a relay C-NA output, for the others
it's a negative programmable open collector output pro-
tected by 100 ohm resistor (ON=0 V DC, OFF=NA) .
[U3, U4] negative programmable open collector outputs

protected by 100 ohm resistor (ON=0 V DC, OFF=NA) .
[NO, C, NC] general alarm relay with clean contacts (one
only for PXC48 and PXC96) .
[F5] for PXC48: no fuse .
[F5] for PXC96: self-restoring 1 .35 A fuse .
[F5] for PXC200: self-restoring 1 .35 A fuse .
A short circuit with open collector output active for a
long time may lead to breakage of the protective resistor
