PLZ-4WL
Monitor Signal Output
Trigger signal output
The trigger signal can be used as a synchronization signal for monitoring the waveform of the
switching operation on an oscilloscope. It can also be used to synchronize with an external
device during sequence execution.
The trigger signal is output from the TRIG OUT connector (BNC connector) on the PLZ-4WL
front panel.
The trigger signal output voltage is approximately 4.5 V. The pulse width is 2 µs or more. The
output impedance is approximately 500
. The TRIG OUT connector is connected to the
chassis electric potential. It is isolated from A COM.
The trigger signal output is generated
under the following conditions.
•
During switching operation.
•
When a step in which trigger output
has been specified is executed
during sequence operation.
Current monitor output
The signal is output from the I MON OUT connector on the PLZ-4WL front panel and across
pins 7 and 8 (pin 8 is common) of the J1 connector.
■
I MON OUT connector (BNC) on the PLZ-4WL front panel
The common is connected to the chassis electric
potential. It is isolated from A COM. For current ranges
H and L, 1 V corresponds to the full scale current; for
current range M, 0.1 V corresponds to the full scale
current. The output impedance is approximately 50
.
■
Across pins 7 and 8 of the J1 connector
The common is connected to A COM. For current ranges H and L, 10 V corresponds to the
full scale current; for current range M, 1 V corresponds to the full scale current.

CAUTION
To avoid damaging the PLZ-4WL, observe the following precautions. Pin 8 of the J1
connector is connected the negative load input terminal. Make sure that the wire of pin 8
does not touch any of the other pins.
