X20SI4100 B&R X20 PLC SYSTEM I/O Module 4 Safe Type A Digital Inputs, 4 Pulse Outputs, 24 VDC



  • 4 safe digital inputs
  • 4 pulse outputs
  • Sink circuit
  • Software input filter configurable for each channel

This module is equipped with 4 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.
