The DC Current Sensor CE-IZ02-32MS1-0.5 0-10mA measures direct current up to 10 mA. It is powered by an external 12 VDC power supply and provides a 0 to 5 VDC analog signal that is linearly proportional to the current measured at the terminal blocks. The sensor can be easily mounted using the screw holes or on a 35 mm wide DIN rail for quick installation. The terminal blocks accommodate conductors up to AWG #16.
To measure the current, the sensor features an internal 50 Ohm resistor, which may result in a slight voltage drop before the voltage reaches the device requiring power. Consequently, the remaining voltage might not be sufficient to power the device, particularly if the power supply has a voltage close to the device's minimum voltage requirements.

For comparison, using a 9V battery running through an LED with a forward voltage of 1.8 V and a 1000 Ohm resistor, there is an approximate drop of 0.35 V due to the 50 Ohm sensing resistor on the 10mA DC Current Sensor. The maximum voltage drop is 0.5 V when the sensor is measuring 10 mA.
It is important to note that the output of this sensor is not clamped at 5 V. If the current being measured exceeds the rated input current, more than 5 V will appear at the output signal. This can potentially damage the Phidget Board (or any other ADC) that it is attached to if the output signal exceeds 5 V for an extended period of time.
