Model SP33X-0700
4-Wire DC I/V Signal Splitter w/USB
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-).
Table 2: Optional AC Current Sensor Turns & Range (for SP336 Model Only)
AC Current Input Range Primary Turns Sensor Output (Red/Black)
0 to 20A AC 1 0 to 11.17mA DC
0 to 10A AC 2 “
0 to 5A AC 4 “
0 to 2A AC 10 “
0 to 1A AC 20 “
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.
