Field of application
The Nivotester FTL825 supplies the Liquiphant FailSafe FTL8x point level switch with direct voltage via a two-wire cable. At the same time, it analyzes the current values (4-20mA discrete) of the Liquiphant and returns a switching signal. The signal inputs of the Nivotester FTL825 are galvanically isolated from the mains and the output and can be ordered Safety-critical systems up to SIL3. For industries where redundant or diverse systems are either not recommended or not possible.
FailSafe point level switch unit for top hat rail mounting.
Ambient temperature: -20 to +60°C (-4 to +140°F)
International explosion protection certificates, overfill prevention WHG
Benefits
Use in safety systems requiring functional safety to SIL3 in accordance with
IEC 61508 Ed.2.0 /IEC 61511-1 / ISA 84-1Proof test: proof testing interval up to 12 years, Slave devices tested at the press of a button
For safety-critical systems up to SIL3 in the chemicals, petrochemicals and oil & gas industries
For applications where redundant or diverse systems are either not recommended or not possible, the longest possible test cycles are desirable, or proof tests are either not possible or only with great difficulty and expense
Integrated locking function (self-holding)
4 switching outputs (can be analyzed separately): 2 as level safety contacts based on the quiescent current principle for a redundant output signal, 1 x signaling contact (e.g. lamp),
1 x fault-signaling contact as changeover contact
