2.2.1 ISOLATED ANALOG PROGRAMMER Functions
The following sections describe the functions of the various signals of the ISOLATED ANALOG
Programmer. Circuit is SELV, and all connections have electrical isolation from the output of the
unit. Pin numbers correspond to the rear panel J4 connector pin out of Table 2–2.
Digital Control Input Signals
ANALOG-CONTROL (Remote/Local): Pin-1, enables remote analog programming with an
active-low logic level. When a low level is applied, the supply will power-up with the analog
interface in control of the output voltage. When high, the power supply will be in local control
mode. Signal return is at J4-2.
EXTERNAL SHUT DOWN (S/D): Pin-14, disables the output when applied and supply is
working in the Remote Control mode. Logic level can be selected with switch SW1-6 to be
active high or low. Signal return is at J4-2.
Digital Control Status Output Signals
VOLTAGE-MODE: Pin-5, nominal 5VDC logic level indicates operation in constant-voltage
mode. Low logic level indicates operation in constant current mode. Signal return is at J4-2.
OVP: Pin-17, nominal 5VDC logic level indicates that the output has been disabled because of
overvoltage protection. Signal return is at J4-2.
FAULT: Pin-18, nominal 5VDC logic level indicates that the output is disabled because of an
over temperature or shutdown fault. Signal return is at J4-2.
Analog Monitor Signals
VOLTAGE MONITOR, 0-5/10V: Pin-19, provides an analog readback of the output voltage
with a 0-5VDC or 0-10VDC signal (user selectable with switch SW1-4) indicating 0-100% of full
scale output. Signal is referenced to J4-6.
VOLTAGE MONITOR, 4-20mA: Pin-4, provides an analog readback of the output voltage with
a 4-20mA signal indicating 0-100% of full scale output. Signal return for the 4-20mA current is
J4-6.
CURRENT MONITOR, 0-5/10V: Pin-7, provides an analog readback of the output current with
a 0-5VDC or 0-10VDC signal (user selectable with switch SW1-5) indicating 0-100% of full scale
output. Signal return is at J4-6.
CURRENT MONITOR, 4-20mA: Pin-24, provides an analog readback of the output current
with a 4-20mA signal indicating 0-100% of full scale output. Signal return for the 4-20mA current
is J4-6.
