Power
Unit power connections are
reverse-polarity protected.
Power Supply (Connect at TB5 or via DIN Rail Bus Terminal):
6-32V DC SELV (Safety
Extra Low Voltage), 1.6W maximum. Observe proper polarity. Reverse voltage
protection included. Current draw varies with voltage as follows (currents indicated
assume dual transmitter mode with both current outputs driving 20mA
into 500Ω
).
SUPPLY
DT333-0700 CURRENT DRAW
CAUTION:
Do not
exceed 36VDC peak
to avoid damage to
the unit. Terminal
voltage at or above 6V minimum
must be maintained across the unit
during operation.

to the DIN Rail Mounting & Removal section for more details.
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 550Ω).
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 power circuits are all 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.
