Passive sensors
Connection method for sensors which are supplied with power by means of the sensor power supply
integrated in the device.
Fig. 9: Connecting a passive sensor, e.g. to input 1 (slot A I).
Item 1: pulse signal
Item 2: PFM signal
Item 3: 2-wire transmitter (4-20 mA)
Item 4: passive sensor connection, e.g. optional Universal extension card in slot B (slot B I, → Fig. 13)
Temperature sensors
Connection for Pt100, Pt500 and Pt1000
!
Note!
Terminals 1 and 5 (3 and 7) must be jumpered when connecting 3-wire sensors (see Fig. 6).
Abb. 10: Connecting a temperature sensor, e.g. to input 1 (slot E I)
Item 1: 4-wire input
Item 2: 3-wire input
Item 3: 3-wire input, e.g. optional temperature extension card in slot B (slot B I, → Fig. 13)
E+H-specific devices
Flow sensors with PFM output
!
Note!
Set the Prowirl measuring device to PFM output (Æ FU 20:
ON, PF)
