Frequency Input Modules from Dataforth
August 17, 2006
Dataforth Corp., Tucson, AZ, adds the 8B45 Series frequency input modules to its SensorLex 8B family of isolated analog signal conditioners. The modules accept a zero-crossing or TTL-level sensor output signal and isolate, convert, and filter it to provide a high-level analog output. Available models measure frequency signals in 8 ranges from 500 Hz up to 100 kHz with signal amplitudes from 100 mVp-p to 350 Vp-p. A 5 V constant voltage excitation source is provided for sensors that require a stimulus. Zero-crossing and TTL input signal paths have built-in hysteresis.
