Malzeme Numarası:
  • reACTION Technology module
  • 8 high-speed safe digital inputs, sink circuit
  • 4 pulse outputs
  • Software input filter configurable for each channel
  • 6 high-speed safe digital outputs, output type B with 0.2 A, source circuit
  • Safe reACTION task cycle times starting at 125 µs
  • Integrated output protection

This reACTION Technology module is equipped with 8 high-speed safe digital inputs and 6 high-speed safe digital outputs. It is designed for a nominal voltage of 24 VDC.

The module can be used to read in digital signals and to control actuators in safety-related applications up to PL e or SIL 3.

Ultrafast reACTION Technology makes it possible to control internal I/O channels with cycle times down to 125 µs. All commands that can be used for reACTION programs are available 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 is equipped with filters that are individually configurable for switch-on and switch-off behavior. The module also provides pulse signals for diagnosing the sensor line.

The outputs are designed using semiconductor technology so that the safety-related characteristics do not depend on the number of switching cycles. The "high-side high-side" variant (output type B) is required for actuators with reference potential (e.g. enable inputs on frequency inverters). It is important to observe the special notices for the cabling in this case. The safe digital output modules have a start interlock on error in the event of network errors.

This module is designed for X20 12-pin terminal blocks.
