External Programming Port - Ametek Amrel PLA Series Operation Manual

EXTERNAL PROGRAMMING PORT

The external programming port provides remote sense inputs, input voltage monitoring, input current monitoring, external
trigger input, external trigger output, and analog programming signal.

Positive remote sense.
Negative remote sense.
Analog Ground. Provides common (reference) connection for EXT_PRG
(PIN 4), VMON (PIN 5), and IMON (PIN 6). When an external
programming function is not used, connect this point to Analog pin 4 to
prevent EMI Noise.
External analog programming input signal. The electronic load can be
programmed externally by 0-10Volts DC or DC + AC voltage (AC voltage
must be biased to above 0V). When external analog programming function
is not used, connect this point to AGND pin 3 to prevent EMI Noise.
Input voltage monitoring signal. Generates a 0-10Volt output signal that is
linearly proportional to the electronic load's 0 to full-scale voltage.
Input current monitoring signal. Generates a 0-10Volt output signal that is
linearly proportional to the electronic load's 0 to full-scale current.
No Connection
Fault signal output. A TTL compatible signal that becomes active (high)
when any of the protections are triggered.
Digital port output. Port can be activated via front panel operation or by
SCPI command PORT 0|1 |off|on. PORT becomes active (high) when the
PORT is on.
Negative Edge Triggered External trigger signal input. A TTL compatible
signal is used to activate the electronic load. TRIG_IN is used to change to
a preset mode or switch between settings in transient mode, such as trigger
the step mode, trigger mode, continuous mode, toggle mode, step auto
mode, step once mode, or pulse mode.
NOTE: IN ORDER TO ENABLE THE TRIG_IN PORT FOR USE, THE
TRIGGER SOURCE MUST BE SET TO EXTERNAL.
External trigger signal output. A TTL compatible signal that is activated
via the Trig-in or GPIB command *TRG. This output follows the state of
the TRIG_IN input. External trigger output is used for triggering
oscilloscopes, power supplies, or other electronic loads that have external
trigger input.
Earth Ground. Provides the common (reference) connection for TRIG_IN
(PIN 10), TRIG_OUT (PIN 11), Fault (PIN 8), and PORT (PIN 9).
