Sensors Powered Independently that Provide Either 12V, 5V or a
10mA DC Output Signal
Caution: When configured for a 10mA DC source input, the
MX001 box expects a current limited 10 mA DC signal to be
supplied by the sensor. Failure to limit this current to 10mA can
damage the sensor input circuitry of the system.
Current limiting can be accomplished by using an external limiting resistor of the
appropriate value (which is dependent upon the sensor's DC signal output
voltage level). This resistor is connected between the S IN+ input of the MX001
box and the sensor.
Approximate Resistance =
