04652E00

Series 9471

  • 16 channels for active 0 / 24 V signals
  • Zone 2 / Division 2 version for connection of circuits acc. to Ex nL, Ex nA, Nonincendive and Non-Ex
  • Galvanic separation between inputs and system
  • Two channels can be used as frequency inputs or counters up to 20 kHz
  • Module can be replaced in operation (hot swap)

The Digital Input Module 24 V is used for the connection of up to 16 contacts with active 24 V signals. The inputs are passive voltage inputs for 0 / 24 V signals. All 16 channels have a common earth (0 V).

Channels 14 and 15 are equipped with a fast comparator and can also be used for frequency measurement or as pulse counters up to 20 kHz.
