What it is and where it fits
The 6ES7141-1BF41-0XA0 is a SIMATIC DP expansion module EM 141 for the ET 200X distributed I/O family. It provides 8 digital inputs rated at 24 VDC, each channel brought to a 5-pole M12 connector. The module is IP66/67 rated, making it suitable for on-machine or washdown zones. Despite the "spare part" designation, the lifecycle is current — still orderable, still supported.
Mounting and integration
Electronic short-circuit protection. No potential separation on the digital inputs. Status indication per input via green LED. Unshielded cable runs up to 30 m.
