Page 22 B - ANALOG OUTPUT A linear 4-20mA signal (option AB: 0-20mA or option AU: 0-10V) output signal is generated according to the calculated flowrate with a 10 bits resolution. The settings for flowrate (SETUP - 2) directly influence the analog output. Note: When the analog output is not used, please make sure that setting B1 is disabled, or else the battery life time will be reduced significantly! When a power supply is available but the output is disabled, a 3.5mA signal will be generated. -

When power is applied to these terminals, the (optional) internal battery will be disabled / enabled automatically to extend the battery life time.
- Page 31 Page 31 Option AI: An isolated 4-20mA signal proportional to the flowrate is available with this option. When the output is disabled, a 3.5mA signal will be generated on these terminals. Max. driving capacity 1000 Ohm @ 30V DC. This option can be battery powered but the life time of the battery is about 2 -3 years. Option AU: A 0-10V DC signal proportional to the flowrate is available with this option.
- Page 32 Page 32 Pulse-signal NPN / NPN-LP: The F127-P-EL is suitable for use with flowmeters which have a NPN output signal. For reliable pulse detection, the pulse amplitude has to go below 1.2V. Signal setting NPN-LP employs a low- pass signal noise filter, which limits the maximum input frequency - read par. 3.2.3. Pulse-signal PNP / PNP-LP: The F127-P-EL is suitable for use with flowmeters which have a PNP output signal.
- Page 33 Page 33 Active signals 8.1V - 12V and 24V: If a sensor gives an active signal, please read par. 3.2.3. The detection levels are 50% of the selected supply voltage; approximately 4V (ACT_8.1) or 6V (ACT_12) or 12V (ACT_24). Active signal selection may well be desired in the case of options PD-PM being supplied for sensor supply.
