Note 1: Shields should be connected at their respective signal source.
Note 2: Unused channel should remain open for minimum power
consumption.
Note 3: More than one external power supply can be used provided the
power supply commons are connected.
Note 4: A Series 217, 0.032A fast-acting fuse is recommended for 4-20
mA current input loops.
Note 5: If the power supply common of an external power supply is not
connected to 0 VDC on the module, then the output of the
external transmitter must be isolated. To avoid "ground loop"
errors, recommended 4-20 mA transmitter types are:
2 or 3 wire: isolation between Input signal and power supply
4 wire: Isolation between input signal, power supply, and 4-20
mA output.
Note 6: If an analog channel is connected backwards, then
erroneous data values will be returned for that channel.
Note 7: To avoid small errors due to terminal block losses,
connect 0 VDC, IN-, and OUT- on the terminal block as
shown. The module’s internal connection alone of these
nodes is not sufficient to permit module performance up
to the accuracy specifications.
Note 8: Choose an output transducer resistance according to the
maximum load/power listed in the Output Specifications.
