Namur Sensor; Analogue Sensor With Voltage Output - NetComm NTC-220 User Manual

NAMUR Sensor

A NAMUR sensor is a range of sensors which conform to the EN 60947-5-6 / IEC 60947-5-6 standards. They
basically have two states which are reflected by the amount of current running through a sense resistor.

Analogue Sensor with Voltage output

There are various analogue sensors that connect directly to the unit which can provide a voltage output. These
would require an external power source which may or may not be the same as the unit itself. The voltage range
they provide can be between 0V and 30V. Some common sensor output ranges include 0V to 10V. These would
work on the unit, The pull up resistor is not activated in this case.
