Q476 Field Configurable Isolator

Brand: Eurotherm
Does not ship to United States

The Q476 is a DIN rail mount, frequency input signal conditioner with 1,800 Vdc 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 Q476 can be configured for any frequency span from 2 to 10,000 Hz.

The input amplitude threshold sensitivity can be adjusted from 150 mVp to 10 Vp 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 to 5 V, 0 to 10 V, 0 to 1 mA, 0 to 20 mA or 4-20 mA.
