Description
Michigan Scientific's MSCF2V04 is one of the most versatile frequency to voltage converters available today. With a digital signal processor at it's heart, the MSCF2V04 can process up to four frequency inputs simultaneously at a rate of up to 120 kHz aggregate between the channels. The outputs are updated within 6 μs to 36 μs at every period of the input signal, providing the most accurate frequency measurement possible. Using the supplied interface software, the user can quickly and easily configure the MSCF2V04 for just about any frequency to voltage application using any Windows 98, 2000, or XP machine with a USB port. The inputs can be configured to accept either digital square-wave pulses with a TTL threshold or magnetic reluctance type sensors with a minimum 350 mV amplitude. The inputs can be individually offset by up to ±10 V and can be as large as ±120 V in amplitude. An analog input is available to synchronize one or more of the channels to an external device such as a fifth wheel. The outputs are scalable to almost any range within the available ±10 V, and the sensitivity is adjustable to almost any value as well. The minimum measurable frequency can be adjusted to anywhere from about 0.15 Hz to 610 Hz. The maximum measurable frequency is 120 kHz for high-speed mode, 85 kHz for quadrature mode, and 35 kHz for standard mode. In quadrature mode, an index pulse is used to set the zero position. If no index pulse is used, the zero position corresponds to the position of the encoder at power-up. For wheel speed applications, an ABS algorithm can be used to quickly detect wheel lock-up. The display can be configured to display output voltage (1 mV minimum resolution) for each channel, trigger status of each channel, or rotational velocity and position (quadrature mode only).
