Module transforms pulse output sensors into speed monitors

摘要

Any sensor with a pulse output can be turned into a speed monitor with a local display and two adjustable switching setpoints, using a mini-display module from ifm electronic. The DP2122 module reduces the load on a PLC compared to using it to evaluate sensor pulses to determine speed. Typical applications include monitoring belt and screw conveyors, fans, centrifuges, separators and other equipment where speed must stay within a specified range. The module can be used with inductive, capacitive or photoelectric sensors, and has an M12 connector, allowing it to be mounted on the sensor or connected via cable. The two switching outputs can be configured as normally open or closed. An IO-Link interface provides real-time transmission of the speed, and can also be used to configure the module. Alternatively, settings can be made via built-in pushbuttons.
