LED Indicators (Front-Panel)
Power PWR (Green)
–
Channel Green ON indicates power is applied to unit (this LED
is sourced from isolated internal 3.3V rail).
Fault FLT - Channel Output (Orange, Each Output, FLT1 & FLT2) -
Orange FLT LED per
current output channel. ON indicates channel current output is open circuit, or the
corresponding current output load resistance is too high to drive accurate current to
it (load resistance is greater than 525
Ω).
ON may also indicate over-temperature if
the output driver die temperature has exceeded 142°C.
Environmental
These limits represent the
minimum requirements of the
applicable standard, but this
product has typically been tested
to comply with higher standards in
some cases.
Operating Temperature:
-40
C to +70
C (-40
F to +158
F). It is recommended this
unit be mounted upright on a DIN rail, allowing free air to flow into the bottom vent,
pass through the unit and out the top vent.
Storage Temperature:
-40
C to +85
C (-40
F to +185
F).
Relative Humidity:
5 to 95%, non-condensing.
Altitude:
Up to 2000 meters.
Isolation:
Input 1/USB, input 2, output 1, output 2, and DC power circuits are
isolated from each other for common-mode voltages up to 250VAC, or 354V DC off
DC power ground, on a continuous basis (will withstand 1500VAC dielectric strength
test for one minute without breakdown). Complies with test requirements of UL
61010C-
1 First Edition, August 9, 2002 “UL Standard for Safety for Process Control
Equipment”
for the voltage rating specified.
Operating Shock & Vibration Immunity:
Designed to comply with IEC 60068-2-6: 10-
500Hz, 4G, 2 hours/axis, for random vibration, and IEC 60068-2-27: 25G, 11ms half-
sine, 18 shocks at 6 orientations, for mechanical shock.
Installation Category:
Suitable for installation in a Pollution Degree 2 environment
with an Installation Category (Over-voltage Category) II rating per IEC 1010-1 (1990).
