The ActionI/Q model Q478 is a DIN rail mount, frequency input signal conditioner with 1800VDC isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for variable frequency drives, magnetic pickups, turbine flowmeters, and other pulse or frequency output transducers.

The input of the Q478 can be configured for any frequency span from 2Hz to 10,000Hz. The input amplitude threshold sensitivity can be adjusted from 150mVp to 10Vp to ensure accurate frequency measurement and minimize transient noise related errors. The maximum input amplitude is 150 Vrms. The output can be set for either 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA.

Advanced digital technology allows the Q478 to be field configured for virtually any frequency input to DC signal output within the ranges specified. Calibration utilizes TouchCALTM technology where the user simply applies the minimum and maximum input frequencies, touching a recessed button to configure the corresponding minimum and maximum output range

Another feature of the Q478 is a 8VDC excitation source common to the input. This can be used as a signal source for relay contacts or as an excitation source for open collector type proximity sensors. The Q478 is DC powered and will accept any power between 9 and 30VDC.
