Description:

Ex isolating switch amplifiers for Namur sensors:

• 1-channel isolating switch amplifiers in 22.5 mm width with an external power supply,
  to transmit and isolate Namur sensor signals from Ex zones 0,1,2 into the safe zone.
• On the output side there is a potential-free relay contact with closing function and an alarm contact for status/error messages.
• The component can be configured using standard FDT/DTM software.
