DESIGNATION
DESCRIPTION
1 (
green
)
ENABLE
+5V TTL applied to this pin enable PDD.
While 0V are applied to this pin or pin is
unconnected module is disabled.
Once
Fault
has occurred module is
blocked till you eliminate fault cause, then
disable
module and
enable
it again.
2 (
orange
)
FAULT
If module is
enabled
and some trouble has
occurred, module automatically stops
operations and sets
Fault
status (
Fault
loop is “closed”).
Fault can be caused by following
reasons:
- overheating
- mains voltage interruption
- maximum pulse energy exceeded
To remove Fault state one should
disable
driver and
enable
it again
In case of normal operations
Fault
loop is
“opened”.
Maximum allowed current in
Fault
loop is
50mA.

)
PULSE 1
+5V TTL pulse should be applied to pin 3
and to pin 8 simultaneously in order to
obtain pulsed current from PDD-300.
In cases if 0V is applied to one of these
pins or at least one of these pins is
unconnected, there will be no current
from PDD-300.

PULSE 2 RETURN
Return of Pulse 2 signal
5 (

)
PULSE 1 RETURN
Return of Pulse 1 signal

CURRENT
PROGRAM
Voltage applied to this pin sets output
current.
0-10V DC are linear with 0-I
MAX
.
8 (
white
)
PULSE 2
+5V TTL pulse should be applied to pin 3
and to pin 8 simultaneously in order to
obtain pulsed current from PDD-300.
In cases if 0V is applied to one of these
pins or at least one of these pins is
unconnected, there will be no current from
PDD-300.
