Models ER-420-AC, ER-420-DC & ER-420-LP
Pulse-signal PNP / PNP-LP
The ER-420 is suitable for use with flowmeters which have a PNP output signal. For a reliable pulse detection, the pulse
amplitude has to go above 1.2V. Signal setting PNP-LP employs a low-pass signal noise filter, which limits the maximum input
frequency (see "Details of Setup Functions" on page 14). For a signal detection level of 50% of the supply voltage, see
"Active signals 8.1V to 12V and 24V" on page 30.
Active signals 8.1V to 12V and 24V
If a sensor gives an active signal, see "Details of Setup Functions" on page 14. The detection levels are 50% of the selected
supply voltage; approximately 4V (ACT_8.1) or 6V (ACT_12) or 12V (ACT_24).
