Pin name Pin number Description
Ext-V In /
Ext-R In (+) 1 Used for voltage/resistance control of CC, CR, CV
and CP mode.
0V to 10V corresponds to 0% to 100% of the rated
current (CC mode), rated voltage (CV mode), or
rated power (CP mode). 0V to 10V corresponds to
the maximum resistance to minimum resistance (CR
mode)
0Ω to 10kΩ corresponds to 0% to 100% or 100% to
0% of the rated current (CC mode), rated voltage
(CV mode), or rated power (CP mode). 0Ω to 10kΩ
corresponds to maximum resistance to minimum
resistance or minimum resistance to maximum
resistance (CR mode)
Ext-V In (+) for
+CV 2 Used for voltage control of Cx+CV mode.
0V to 10V corresponds to 0% to 100% of the rated
voltage.
A COM 3 Connected to the negative load input terminal on the
rear panel.
SUM I Mon Out 4 Used during master/slave operation. Connected to
SUM I MON of the J2 connector.
PRL In(+) 5 Used during master/slave operation. Connected to
PRL OUT+ of the J2 connector.
PRL In(-) 6 Used during master/slave operation. Connected to
PRL OUT- of the J2 connector.
Ext-Load On(+) 7 Turns on the load with low (or high) TTL level signal.
Pulled up the internal circuit to 5V using 10kΩ.
I Rang) 8 External range switch input
*1 *2
Pulled up the inter
nal circuit to 5V using 10kΩ.
I Rang) 9
Ext Alarm In(+) 10 Activates alarm with low TTL level signal input.
Pulled up the internal circuit to 5V using 10kΩ.
Ext Trigger In(+) 11 When paused, clears the pause when a low level
TTL signal is applied for 10us or longer.
Pulled down the internal circuit to A COM using
100kΩ.
A COM 12 Connected to the negative load input terminal on the
rear panel.
Load On Out(+) 13 Turns on when load is on. Open collector output by a
photo - coupler.
