To provide accurate control of, say a conveyor motor speed, often requires a feedback of the actual speed of the adjacent machine; if this is only available as a pulse sequence the new DW2503 digital converter from ifm electronic offers a solution. The new upgraded DW2503 can accept high-frequency incoming pulses up to a maximum 10kHz, from as low as 1 pulse per minute. The user can scale the conversion of these pulses into the desired 0/4 to 20mA or 0 to 10V signal. If needed, the DW will also invert the signal.
As a bonus 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 extended operating temperature range down to 40degC below zero; the newly developed luminous OLED display is not only clearer but also brighter, and the menu-guided parameter setting are designed for maximum user friendliness.
The DW2503 will operate on a wide range of voltages, AC or DC, and provide DC supply to input sensors. As a market leader in the field, ifm electronic can advise on and supply suitable sensors, such as inductive or magnetic pulse pickups, or shaft encoders.
