Speed monitors

In addition to the high input frequency from as low as one pulse per minute up to 60,000 pulses / minute and configurable functions, these also include an extended operating temperature range down to 40 °C below zero. The newly developed luminous OLED display is not only clearer but also brighter.

Speed monitors DD2503 and DD2603 monitor the rotational speed of one channel with two separately adjustable limit values. A separate switched output is assigned to each limit value, and an analogue signal is provided for further processing or display. The DD2505 and DD2605 monitor two separate input channels, each having one switch point. The DD2603 and DD2605 can also check that the sensor cabling is intact.
