16 NAMUR in (16 x digital in Ex i)

PROFIBUS-Interface for zone 1/21
  • 16 channels
  • LED display
  • for NAMUR sensors
  • DIN EN 60947-5-6
  • for mechanical contact
  • galvanic isolation
  • group error messages
  • Ex ia/ib
  • Cable monitoring (can be disabled)
  • Programmable address on front panel


In the Ex i version, the MODEX Ex i digital in module with 16 digital inputs enables 16 binary signals to be evaluated. For example, NAMUR sensors, optocouplers, mechanical contacts or other actuating elements can be imported as signals in an intrinsically safe manner. The module is connected to the process control system via the PROFIBUS-DP. This is also displayed on the module itself using LEDs. Diagnostics data indicating the status of the outputs with respect to a disconnection or short-circuit can also be transmitted in addition to the user data. This is also displayed on the module itself using LEDs.
