Wago Corporation’s two zero- to 10-VDC 859 Series Voltage-to-Frequency Converters (VFCs) provide output frequencies of zero to 1.5KHz or zero to 25KHz for pulse generation. The VFCs are designed to simplify simulators by replacing standalone frequency generators, rotating equipment and associated cabling, allowing machine builders to design more cost-effective simulators for industry and transportation, the company says. Serving industrial applications, such as variable frequency drives, Wago’s VFCs mimic motor encoders to generate pulse inputs for controlling lighting or machine speed. Isolated VFCs are also available for excessively noisy environments or applications with high potential differences between machinery. Within vehicle/non-automotive transport simulators, the VFCs pulsate to mimic wheel speed for tachometer and speedometer readings – no costly subassemblies with rotating tires or cabling. Beyond drivetrain development, streamlined simulators can help develop or economize driving skills.
