Function module DIO8-Z (2 encoder channels and 2 digital in- or outputs)

The function module DIO8-Z is a compact counter module with 6 counter inputs. Therewith e.g. 2 encoder (A,B,Z) with 5V, 24V or 2 absolute encoder (RS422) can be connected. This module provides 2 digital inputs or outputs (2A) too.

  • insertion stripe with description field for every signal
  • cage-clamp connector with 2 lift arms or bolt flanges on side
