Relay Modules

Standstill / speed monitoring

Stand-still/speed relays monitor the rotation of drives to generate a control signal at zero speed or when a set speed is exceeded.

Extension modules

  • Prewired rail-mounted modules
  • Safety category 3 acc. to EN 954-1
  • Positively driven output contacts
  • Connection monitoring of the proximity switches

These modules have measuring circuits in redundant configuration with 2-channel control by proximity sensors, either as pnp or npn input. The thresholds are either fixed or can be adjusted up to 26000 IPM. Zero-speed monitors can also work without sensors by measuring the remanence voltage of the coasting motor and evaluating it at zero speed.

  • Release safety gate interlocks when the stationary condition of a dangerous movement is detected
  • Work with opened safeguard devices and reduced speed during the set-up mode of the machine
