Endress+Hauser Liquiphant M FTL50H - FEL51 (AC) - Compact Housing Specifications; Compact Housing: Power and Wiring; Compact Housing: Output and Load

Liquiphant M FTL50(H), FTL51(H)
Endress+Hauser 7
Electronics FEL51 (AC, in compact housing)
Power supply Supply voltage: 19...253 V AC
Power consumption: < 0.83 W
Residual current consumption: < 3.8 mA
Short-circuit protection
FEM51 overvoltage protection: overvoltage category III
Electrical connection Two-wire AC connection
Output signal
Signal on alarm Output signal on power failure or in the event of damaged sensor: < 3.8 mA
Connectable load • For relays with a minimum holding power/rated power > 2.5 VA at 253 V AC (10 mA) or
> 0.5 VA at 24 V AC (20 mA)
• Relays with a lower holding power/rated power can be operated by means of an RC module connected
inparallel
• For relays with a maximum holding power/rated power < 89 VA at 253 V AC or < 8.4 VA at 24 V AC
• Voltage drop across FEL51 max. 12 V
• Residual current with blocked thyristor max. 3.8 mA
• Load switched directly into the power supply circuit via the thyristor.
Transient (40 ms) max. 1.5 A, max. 375 VA at 253 V or max. 36 VA at 24 V (not short-circuit proof)
Always connect in series with a load!
Check the following:
• The residual current in
blocked state (up to 3.8 mA)
• that for low voltage
– the voltage drop across
the load is such that the
minimum terminal voltage
at the electronic insert
(19 V) when blocked is not
undershot.
– the voltage drop across
the electronics when switched
through is
observed (up to 12 V).
• That a relay
cannot de-energise with
holding power below 3.8 mA.
If this is the case, a resistor
should be connected parallel
to the relay.
(RC module available on request).
