Electrical Installation - Sensor Partners i-Tec USB Serie Guía Del Operario

ELECTRICAL INSTALLATION

The sensor to electronics cable is a 1 m PVC cable. One end is attached, at the fac-
tory, to the sensor head. The other end has a pair of wires and a shield (ground) wire.
WIRING
The I-Tec USB sensor can be used in 3 different ways as shown below. To use the 4-20
mA output, connect the I-Tec USB sensor to the controller/indicator with the 24 V DC
power supply in the loop using the following table and connection diagram as a
guide. The maximum loop impedance is 900 ohms. Note: The I-Tec USB sensor
must be grounded at only one point, either the cable shield or the sensor housing.
Output
4 to 20 mA
Alternatively, to use the USB output, connect the I-Tec USB sensor to a PC using
the cable provided. No external power supply is required when using the USB out-
put. The I-Tec USB sensor can also be used with both the 4-20 mA loop and USB
connected, provided that the negative terminal of the 24 V DC power supply being
used is not grounded. Note: The SP- software must be installed before connecting
the sensor to a PC.
