Produktové číslo:
  • reACTION technology module
  • 4 high-speed digital inputs
  • 4 high-speed digital channels, configurable as inputs or outputs
  • 1 ABR incremental encoder input 24 V
  • Pulse width modulation
  • 24 VDC and GND for encoder supply
  • Supports blackout mode

This reACTION technology module has four high-speed digital inputs and four high-speed digital mixed channels. All connections are designed for 1-wire connections. All inputs are designed for sink connections, the outputs for push-pull connections.

Ultrafast reACTION Technology makes it possible to control the integrated I/O channels with response times down to 1 μs. All of the commands that can be used for reACTION programs are provided as function blocks in special libraries (e.g. AsIORTI). Programming in compliance with IEC 61131-3 requirements takes place in the Function Block Diagram editor in Automation Studio.

The module supports blackout mode. In blackout mode, programmable module functionality persists even if the network fails.
