Safety over IO-Link - Safe input/output modules


IO-Link for safety-related applications

Thanks to the “PROFIsafe” transmission protocol, standard fail-safe sensors and actuators can also be operated via IO-Link.

Only the PROFIsafe IO-Link module is required. It offers 8 safe digital inputs (OSSD) and 4 safe outputs. The innovation: In terms of the hardware, the module is simply connected to a normal IO-Link master via IO-Link. The special PROFIsafe transmission telegram ensures a "tunneled" connection with the safety controller within the standard IO-Link communication. At the same time, it meets the safety levels SIL 3 according to IEC 61508 / EN 61508 and PL e according to EN ISO 13849-1.

Powerful fail-safe outputs
A separate 24 V supply via L-coded M12 sockets makes it possible to connect powerful actuators. The outputs can be configured to be PNP or NPN switching.
