User I/O connections
Input/output signals
The Pulstar p100’s input/output signals are divided into three categories: auxiliary DC power, input signals,
and output signals. Signals in each category are fully described in the following sections.
Auxiliary DC power
Pulstar’s
User I/O
connector provides auxiliary DC power for driving external inputs or outputs connected
to the
User I/O
port. Pin 4,
+5 VDC Auxiliary Power
, and Pin 5,
+24 VDC Auxiliary Power
, are protected
by self-resetting fuses rated at 0.5 A. Pin 12,
Auxiliary DC Power Ground
, is connected to chassis ground
while all other
User I/O
pins are floating with respect to chassis ground. Figure 3-8 illustrates Pulstar’s
internal DC supply wiring.

Pin 4 + 5 VDC Auxiliary Power
This connection pr5 VDC for driving external inputs or outputs. The
+5 VDC Auxiliary
Power
output can source up to 0.5 A and is protected by a 0.5 A self-resetting fuse. The return
(ground) path must be through Pin 12,
Auxiliary DC Power Ground
.
Pin 5 + 24 VDC Auxiliary Power
This connection pr24 VDC for driving external inputs or outputs. The
+24 VDC Aux-
iliary Power
output can source up to 0.5 A and is protected by a 0.5 A self-resetting fuse. The
return (ground) path must be through Pin 12,
Auxiliary DC Power Ground
.
Pin 12 Auxiliary DC Power Ground
This connection provides a ground (earth) connection for +5 and +24 VDC auxiliary power out-
puts. This pin is the only
User I/O
pin that is connected to the laser’s chassis ground. Do not use
this pin for grounding if I/O circuits are powered from an external customer-supplied DC power
source.
