Liquiphant M FTL51C
8 Endress+Hauser
Electronic insert FEL52 (DC PNP)
Power supply Supply voltage: DC 10 to 55 V
Ripple:
 1.7 V, 0 to 400 Hz
Current consumption:  15 mA
Power consumption:  0.83 W
Reverse polarity protection
Overvoltage protection FEL52: overvoltage category III
Electrical connection Three-wire DC connection
Output signal
Signal on alarm Output signal on power failure or in the event of damaged sensor: < 100 μA
Connectable load • Load switched via the transistor and separate PNP connection,
 DC 55 V
•Load current
 350 mA (pulsed overload and short-circuit protection)
• Residual current < 100 μA (with transistor blocked)
• Capacitance load  0.5 μF at 55 V,  1.0 μF at 24 V
• Residual voltage < 3 V (with transistor switched through);
Switches the load via the transistor (PNP) and
separate connection.
Preferably used with programmable logic
controllers (PLC),
DI modules as per EN 61131-2.
Positive signal at switching output of the
electronics (PNP); Output blocked on reaching
point level.
