Asterion DC Series Calibration
M330460-01 Rev D 3-47
Pin Reference Type Functional Description
21 IMON ANALOG OUT
Monitor signal for output current: 0-10
VDC = 0-100% of full-scale output
current. Minimum recommended load
resistance is 100 KΩ and maximum
load is 20kΩ. Circuit return is pin 22.
22 MON_RTN ANALOG GND Return for Pin 6, 21, 35.
23 Not Used Not Used Not Used
24 TRIG_OUT DIGITAL OUT
User digital output - cause to be
assigned by user. Output high state
either min 4.5V or voltage on Pin 30
(USER_PWR) minus 1V, whichever
is higher. Maximum current of 0.5A.
25 DIO_OUT1 DIGITAL OUT
Output low for CV and high for CC.
Output high state either min 4.5V or
voltage on Pin 30 (USER_PWR)
minus 1V, whichever is higher.
Maximum current of 0.5A.
26 FAULT_OUT DIGITAL OUT
High state indicates fault. Output
high state either min 4.5V or voltage
on Pin 30 (USER_PWR) minus 1V,
whichever is higher. Maximum
current of 0.5A.
27 DIO_OUT2 POWER OUT
Output low for CV or CC and high for
CP. Output high state either min 4.5V
or voltage on Pin 30 (USER_PWR)
minus 1V, whichever is higher.
Maximum current of 0.5A.
28 RTN_UPWR POWER GND Return for Pin 24, 25, 26, 27.
29 RTN_AUX5 POWER GND Return for Pin 43 (5V_AUX).
30 USER_POWER POWER IN
Optional- User can connect between
5V to 24V to control digital
output/relay output voltage. If left
unconnected, digital and relay
outputs have 4.5V high states.
31 ON/OFF_ISO DIGITAL IN
Isolated remote-control input for
output on/off with a logic signal: a
logic-high, 3.3V to 24V signal will
enable (turn-on) the output of the
supply, and a logic-low signal
disables (turns off) the output. This
control input is optically isolated from
the output power negative terminal of
the power supply (up to 500 VDC).
Signal return is Pin 16 (RTN_HV).
