VEGAPULS 56V 17
Measuring system with five VEGAPULS 56V Ex, 56V Ex0 per two-wire line
via separator VEGATRENN 548V Ex on the processing system
VEGALOG 571
• Two-wire technology, voltage supply and digital output signals via one two-wire line from the
separator
• Five sensors on one two-wire line
• Measured value indication integrated in the sensor
• Optionally external indicating instrument with analogue and digital indication (can be
mounted up to 25 m separated from the sensor)
• Adjustment with or without adjustment module MINICOM (can be plugged into the sensor or
into the external indicating instrument VEGADIS 50)
• Max. resistance of the signal line 15␣
Ω
per wire or 1000␣ m cable length (see also approval
certificates of the separators)
