3.3.3 Monitor output connector
This product has a monitor output connector for observing an output voltage. An output waveform can be
observed by connecting an oscilloscope directly to the connector.
The monitor output connector outputs a voltage, regardless of the output on/off setting. A voltage as small
as 1/100 of the main output level is output.

Output terminal BNC connector (rear)

Monitor ratio 1/100 of output voltage (in phase as output voltage)

Output impedance 50

3.3.4 External control I/O connector
This product has an external control I/O connector with D-sub 9 pins.
To turn on output with the external control I/O function, turn on the power after depressing DIP switch 4
to be set at Power-on. (A DIP switch setting change made after operation is started is not reflected.)
Output on/off control can be exercised externally by using a no-voltage contact. (About the example used
external switch Refer to “
Figure 3-5. Example for I/O control by using external switch ”.)
If output is turned on with the external control I/O function, the output on/off switch (OUTPUT) on the
front panel can only be set to OFF.
To turn on output again after output is turned off using the output on/off switch (OUTPUT), the control
signal must first be turned off prior to turning on.
The overload state and output on/off state can be monitored externally. The overload state is indicated
when a short circuit is made between pins 3 and 8. The output on state is indicated when a short circuit is
made between pins 9 and 5.
After the external signal input level was changed, approx. 10 ms or more might be required for the
controller to execute a function as a maximum response time. “Output ON/OFF” additionally requires the
similar time for a response of a relay device.
