Active signals 8.2 V and 24 V
The unit is suitable for flowmeters with an Active signal. The detection levels are about 50% of the
selected supply voltage; approximately 4 V (ACT_8.1) or 12 V (ACT_24). See
SETUP 4:
FLOWMETER [»26]
for more information.
Active signal selection may be desired in the case of power supply type PD being supplied for
sensor supply.

6.4.11 TERMINALS T1-T4: TEMPERATURE INPUT PT100 - TYPE TP
The E126-P-EL type TP requires a PT100 element (RTD) as temperature sensor. The E126-P-EL
uses the International Temperature Scale of 1990 Temperature vs Resistance table (ITS-90) to
calculate the measured temperature. See
Menu 5: Temperature - with type TP (PT100) [»27]
for
configuring the temperature input.
The sensor can be connected in 2, 3 or 4 wire configuration, as indicated in the figure below.
