Malzeme Numarası:
  • 8 safe digital inputs
  • 4 pulse outputs
  • Sink circuit
  • Software input filter configurable for each channel
  • Single-width module

This single-width module is equipped with 8 safe digital inputs. It is designed for a nominal voltage of 24 VDC.

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

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.

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