Nivotester FTL825 FailSafe ©Endress+Hauser

Point level switching unit for Liquiphant FailSafe FTL80, FTL81 and FTL85

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.
