Reed-switch:
The E112-P is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce from the
reed-switch, it is advised to select REED LP - low-pass noise filter, which limits the maximum input
frequency (read par. 3.4.).

NAMUR-signal:
The E112-P is suitable for flowmeters with a Namur signal. The standard E112-P is not able to power the
Namur sensor, as an external power supply for the sensor is required. However, an 8.2V sensor supply
voltage can be provided through terminal P4. See paragraph 3.4. for more information.
