It can also evaluate safe rotary encoder signals. The module features two redundant microprocessors and self-monitoring capability. A separate, safely isolated power supply ensures availability. Five safety modes can be parameterised to suit the required application profile: safely limited speed (SLS), safely limited speed range (SSR), safe direction input (SDI), safe operating stop (SOS), safe speed monitoring (SSM).
The SK TU4-PNS module is available for NORDAC LINK, NORDAC FLEX and NORDAC PRO series inverters with STO functionality, thus covering drive electronics for control cabinet installation, field distribution systems, and motor-integrated units.
