gauge, and shielding. Make sure the U141v+'s
power is off before wiring any inputs or
outputs.
• Thermistor: Precon type 2 (10kohm at
77°F). Input voltages should range
between 0.489V and 3.825V for
thermistors.
• 0 to 5VDC: When using 0 to 5VDC
signals, remove the pull up jumpers of
the U141v+. The pull up jumpers are
located behind the input port. You must
remove the cover to access the pull up
jumpers. The output impedance of a 0
to 5VDC source must not exceed
10kohms. The input impedance of the
U141v+ is approximately 1Mohm.
• Dry Contact: A 5VDC wetting voltage is
used to detect contact position. This
results in a 0.5mA maximum sense
current when the contacts are closed.

Using the LogiStat
Use Figure 10 and Figure 11 on page 8 to wire
a LogiStat, LogiStat Plus, or LogiStat Pro to
the U141v+.
Automated Logic Corporation recommends a
specific wire to connect the U141v+ to the
LogiStat. This 22AWG solid copper wire is
available from Magnum Cable Corporation,

about using a LogiStat sensor.
Digital Output Wiring
The U141v+ has one digital output that can be
connected to a maximum of 24 Volts AC/DC
(see Figure 12). Each output is a dry contact
(rated at 1A maximum) that is configured as
normally open.
