Analog Programming (APG) and Isolated Analog Programming (ISOL)
M370430-01 Rev B 4-21
Table 4-4 AUX Output and ISOL Connector Pins and Functions J3
Isolated Common (Isolated from Main Output and Communication.
Return wire for +5 V, +15 V Auxiliary Voltage.
Isolated Analog Voltage Programming Input
Isolated Analog Current Programming Input
Isolated Voltage Monitor. Scaled to the value of the Voltage Analog
Programming Level.
Isolated Common (Isolated from Main Output and Communication.
Return wire for control signals, monitoring and programming.
Isolated Current Resistive Programming
Isolated Voltage Resistive Programming
Isolated Current Monitor. Scaled to the value of the Voltage Analog
Programming Level.
Shutdown. Input to power supply to disable output. This input has
user selectable negative logic operation via front panel or remote
digital input/output.
PS_GOOD. Power supply output enabled.
Interlock. Dry contact type. Shorting pins J3.14 and J3.15 while the
interlock functionality is enabled, will enable the output of the power
supply.
1. Important: Isolated monitor lines are only valid when Isolated analog programming modes are
used for the respective voltage and current control. If local control, digital control or non-isolated
APG is used, the non-isolated monitor lines should be used as the isolated monitor lines will not
accurately reflect the output state of the power supply.
2. Use unshielded cable up to 9.84 feet (3 m) length with high-density D-Sub type connector and a
ferrite bead (Fair-Rite part number 0443164251).
CAUTION: Equipment damage
Do not drive or apply a voltage to pins J3.14 (Inter_Lock 1) or to pins J3.15
(Inter_Lock 2).
