X20SI4100
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.
