Characteristics
1
FOLDBACK
Output signal, active-low; asserted when in foldback
mode; open-collector of opto-isolator transistor; emitter
is connected to Pin-9. (See OUTP:PROT:FOLD
command in the Output SCPI Command Subsystem,
Section 6.7 of this manual).
60 VDC, max.,
4 mA DC, max.
2
SHUTDOWN
Input signal, TTL active-high; immediate shutdown
when signal is pulled high; open-anode of opto-isolator
diode with internal 1kΩ series resistor; cathode is
connected to Pin-9.
12 VDC, max.,
- 5 VDC, max.
reverse voltage
3
FAULT
Output signal, active-low; asserted when a fault is
recorded in the fault register; open-collector of opto-
isolator transistor; emitter is connected to Pin-9.
60 VDC, max.,
4 mA DC, max.
4
TRIGGER
OUT
Output signal, active-low; synchronization pulse for 10
ms when a change in the output occurs; open-collector
of opto-isolator transistor; emitter is connected to Pin-9.
60 VDC, max.,
7 mA DC, max.
5
COMMON
Return for all relay contacts. Could be optionally
connected to Pin-9, externally, or internally with jumper
JP1 on rear panel Ethernet Connector PWA, 5550387.
Isolated from Pin-9
6
POLARITY
Output signal, asserted (internal relay contacts close to
Pin-5, COMMON) when negative output polarity is
programmed (e.g. OUTPut:POLarity INV) to program
negative voltage (e.g., SOURce:VOLTage -5.0)
2 ADC, max.,
30 VDC, max.
7
ISOLATION
Output signal, asserted (internal relay contacts close to
Pin-5, COMMON) when the output relay is programmed
ON (e.g., OUTPut:ISOlation ON).
2 ADC, max.,
30 VDC, max.
8
SENSE
Output signal, asserted (internal relay contacts close to
Pin-5, COMMON) when the sense relay is programmed
ON (e.g., OUTput:SENse ON).
2 ADC, max.,
30 VDC, max.
9
ISO
COMMON
Return for all opto-isolator signals. Could be optionally
connected to Pin-5, externally, or internally with jumper
JP1 on rear panel Ethernet Connector PWA, 5550387.
Isolated from Pin-5
10
TRIGGER IN
Input signal, TTL active-high; provides external
hardware triggering of sequence functions and of
voltage and current ramp functions; open-anode of
opto-isolator diode with internal 1kΩ series resistor;
cathode is connected to Pin-9.
12 VDC, max.,
- 5 VDC, max.
