Frequently Asked Questions
-
Q: What is included in this kit versus buying a single PM857?
A> This PM857K02 kit includes two controller units and the essential cables to connect them for a redundant pair, providing a ready-to-deploy high-availability solution. -
Q: Is the SM812 safety module included?
A> No. The SM812 module is required to achieve SIL 2/3 functionality and must be purchased separately. -
Q: What is the main benefit of redundancy?
A> It ensures continuous operation; if the primary CPU fails, the backup takes over within milliseconds, preventing process downtime.
