6.3.5

PFM output (electronic insert FEL67)

• For connecting to the Nivotester FTL325P and FTL375P switching units from Endress

+Hauser

• PFM signal transmission; pulse frequency modulation, superimposed on the power

supply along the two-wire cabling

• Functional testing without level change:

• A functional test can be performed on the device using the test button on the

electronic insert.

• The functional test can also be prompted by disconnecting the supply voltage or

triggered directly by the Nivotester FTL325P and FTL375P switching unit.

Supply voltage

U = 9.5 to 12.5 V

DC

Reverse polarity protection

Comply with the following according to IEC/EN61010-1: provide a suitable circuit

breaker for the device.

Power consumption

P ≤ 150 mW with Nivotester FTL325P or FTL375P

Behavior of output signal

• OK status: MAX operating mode 150 Hz, MIN operating mode 50 Hz

• Demand mode: MAX operating mode 50 Hz, MIN operating mode 150 Hz

• Alarm: MAX/MIN operating mode 0 Hz

Terminals

Terminals for cable cross-section up to 2.5 mm

2

(14 AWG). Use ferrules for the wires.

Overvoltage protection

Overvoltage category II
