Programming Manual
M330517-01 Rev C 9-51
Open collector transistor output, Collector is connected the 26-pin
connector. Emitter point of transistor is connected to common return pin
of the interface connector.
Signal return: Pin 26
Voltage Rating: Maximum 30 V, Minimum 3V for Active High, Sink
Current: 50mA
22
CH3-OUTPUT-
ON-OFF DIGITAL
INPUT
Remote-control input for output on/off with a logic signal: a logic-high, will
enable (turn-on) the output of the supply, and a logic-low signal disables
(turns off) the output.
Signal connects to Open-anode of opto-
isolator diode with 1kΩ series
resistor internal to power supply
Signal return: Pin 26
Voltage Rating: Maximum 24 V, Minimum -5V
Low state 0.3 V max, High State 2.7 V min.

CH3-CV/CC-
STATUS DIGITAL
OUTPUT
User digital output. Output low for Constant Voltage (CV) mode and high
for Constant Current (CC) mode.
Open collector transistor output, Collector is connected the 26-pin
connector. Emitter point of transistor is connected to common return pin
of the interface connector.
Signal return: Pin 26
Voltage Rating: Maximum 30 V, Minimum 3V for Active High, Sink
Current: 50mA

CH3-OUTPUT-
ON/OFF-
STATUS
DIGITAL
OUTPUT
Output Signal, High state indicates output of the power supply is enabled.
Open collector transistor output, Collector is connected the 26-pin
connector. Emitter point of transistor is connected to common return pin
of the interface connector.
Signal return: Pin 26
Voltage Rating: Maximum 30 V, Minimum 3V for Active High, Sink
Current: 50mA.

CH3-Remote
Inhibit
Input
Switch/
Relay
Contact
Switch/Relay contact closure or direct short from this terminal to signal
return is required to enable/disable the output of the power supply.
Opening the contact would disable the output. Upon contact closure, if
remote inhibit is selected as live mode, the fault would be cleared, and
output could be enabled from the front panel or by issuing the SCPI
command.
If remote inhibit is selected as Latch mode, the output will be disabled,
Output could not be enabled upon the contact closure. Fault should be
cleared by issuing the SCPI command OUTP<n>:PROT:CLE or by
clearing the fault from the front panel screen.
Remote circuit must sink up to 10 mA from 5 VDC to enable.
Signal return: Pin 26
26 RTN RETURN Return/GND. Pins 8,17 and 26 are shorted internal to the power supply.

CAUTION!
All the three channels signal returns (Pin 8, 17 and 26) are shorted internally to the
power supply. Applying a voltage potential between them would damage the power
supply.
