B&R X20SI4110
4 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 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.
