Shielded cable is used to reduce the unwanted electrical noise signals picked up by the cable. This is particularly important when using sensitive analog input modules like thermocouple modules. Shielded cable provides an extra layer of insulation around the conductors, which blocks the noise signals from interfering with the sensor's signal. It does not carry higher current or lower resistance or insulate the circuit from other cables.
