Frequency-to-current converter
13 November 2013
To provide accurate control, for example of a conveyor motor speed, often requires feedback of the actual speed of the adjacent machine; if this is only available as a pulse sequence the new DW2503 from ifm electronic offers a solution.
The upgraded DW2503 can accept high-frequency incoming pulses to a maximum 10kHz, from as low as 1 pulse/min. The user can scale the conversion of these pulses to the desired 0/4 to 20 mA or 0 to 10V signal. If needed, the DW will also invert the signal.
The DW also features a switched output in the form of a relay and a solid-state transistor, allowing the user the set an alarm signal. The output can be set to stay on for a chosen time.
ifm electronic has upgraded the original DW frequency converter to cover an operating temperature range down to -40°C; the luminous OLED display is clear and bright, while the menu-guided parameter setting is designed to be user-friendly.
