A.2.2 Digital Inputs - Festo CAMC-G-S3 Manual

A Technical appendix
The safe brake control of the CAMC-G-S3 is designed for SIL3 / EN 61800-5-2.
Please check whether the clamping unit you are using achieves a PL r to meet SIL 3. The
clamping unit itself usually has a lower classification, meaning that the safety function
SBC, in combination with the clamping unit, only achieves the lower classification.
A.2.2 Digital inputs
The relevant standards for command devices which request safety functions must be observed, e.g. EN
ISO 13850 for emergency stopping.
