Digital Input Output Module NAMUR for Ex n Zone 2 Series 9471/35

Digital Input Output Module NAMUR for Ex n Zone 2 Series 9471/35
17617E00

Series 9471/35

  • 16 channels can be adjusted in pairs as digital inputs or outputs
  • Suitable for NAMUR proximity switches, 3-conductor PNP proximity switches with external supply, contacts and low power solenoid valves
  • Up to 8 channels can be used as frequency/counter inputs; with rotation direction recognition
  • Line fault monitoring
  • LED display for signal and errors for each channel
  • Energized module can be replaced in hazardous areas (hot swap)
  • Function-compatible replacement for IS1 I/O modules: 9470/25 and 9471/15 series

The digital input output module can connect up to 16 non-intrinsically safe digital signals to the IS1+ remote I/O system. All channels can be configured as input for NAMUR proximity switches (EN 60947-5-6), 3-conductor PNP proximity switches with external supply, for passive contacts and as output for connection of low power solenoid valves (in pairs with adjustable parameters). Up to 8 inputs can be used as frequency inputs or as counters up to 20 kHz. In the "rotation direction recognition" and "forward/backward counter" operating modes, it is up to 4 inputs. All inputs and outputs are monitored for short circuiting and line breakage.
