Electronic speed monitor with safety certification

The electronic speed monitors monitor as many as 4 programmable speed ranges (overspeed, underspeed and standstill) with a high level of switching accuracy, including at low operating speeds. The speed monitors are certified for safety applications up to SIL 2 / PL d. If a programmed speed is exceeded or is too low, the respective switching output switches. As a consequence, speed monitoring plays its part in system and personnel protection. The speed monitors are installed on motors on cranes, in mining operations as well as in rolling mills and more. When devices are swapped it is possible to transfer the parameters previously stored on the first device to the new device.
