Frequency input modules

Tucson, Ariz.— DSCA45 frequency input modules are said to provide a simple, low cost method for interfacing magnetic pulse or "zero-crossing" signals, to data acquisition and control systems. Each module provides a channel of pulse or frequency input, which is isolated and converted to a standard analog voltage or current output.

Tucson, Ariz.— DSCA45 frequency input modules are said to provide a simple, low cost method for interfacing magnetic pulse or "zero-crossing" signals, to data acquisition and control systems. Each module provides a channel of pulse or frequency input, which is isolated and converted to a standard analog voltage or current output. The modules will accept TTL-level or zero-crossing signals in various ranges from 0-500 Hz to 0-100 kHz and convert them to proportional 0-10 V, 0-20 mA, or 4-20 mA output signals. Input levels may range from 60 mV p-p to 350V p-p, and output hysteresis is provided for each signal type. Dataforth
