Siemens SIRIUS 3TK2810 Standstill & Speed Monitors

Siemens SIRIUS 3TK2810 Standstill & Speed Monitors

SIRIUS 3TK2810 safety relays with special functions: sensorless standstill monitors and speed monitors with integrated protective door monitoring.

Key features

  • SIL 3 (IEC 62061 / IEC 61508) and PL e (ISO 13849-1)
  • 3TK2810-0 detects motor standstill from residual voltage without sensors; usable with frequency converters
  • 3TK2810-1 monitors standstill and speed with NPN/PNP or NAMUR proximity switches and encoders
  • Integrated monitoring of a spring-locked protective door on speed monitors
  • Display for parameterization and permanent diagnostics (3TK2810-1)
  • Screw or spring-loaded terminals
