Pilz PNOZ s9 24VDC 3 n/o t 1 n/c t
The Pilz PNOZ s9 24VDC 3 n/o t 1 n/c t is a highly versatile safety relay from the PNOZsigma series that serves two main functions: it can act as a standalone safe timer relay or as a time-delayed contact expander module.
The abbreviation "t" next to the contacts indicates that all of its safety and auxiliary outputs are time-delayed. It is commonly used to safely time control machinery, such as adding a delayed release to an electrical safety gate interlock until a hazardous spin-down sequence finishes.
