Input...continued
The output wires of this sensor are polarized with red as plus (+) and black as minus
(-). Normally these output wires are attached to one end of a user supplied cable,
while the other end connects to the process current input terminals at TB1 of this
module, as shown above (current input to input+ and returned via input-).

AC Input Burden
: A function of the wire gauge resistance used for primary turns (the
current carrying wire being monitored).
AC Current Sensor to Transmitter Wiring Distance
: 400 feet maximum for 18 gage
wiring. Other wire gauges can be used if the resistance of both wires is less than 5
.
AC Input Overload
: The AC current sensor will withstand overload conditions as
follows:
•
20 times full scale for 0.01 seconds.
•
10 times full scale for 0.1 seconds.
•
5 times full scale for 1.0 second.
