G478
Provides an Isolated DC Output in Proportion to input Frequency

Easy Field Configurable Input Ranges from 2Hz to 10,000Hz Eliminates Ground Loops with 1800VDC Input-to-Output Isolation Five (5) Field Configurable Output Ranges: 0-5V, 0-10V, 0-1mA, 0-20mA, 4-20mA Ultra Slim 12.6mm Housing Mounts on DIN Rail for High Density Installations 150mV to 150V Input Amplitude Level Advanced 'Touch-CalTM' Technology for Simplified Ranging Flexible Power Supply Accepts 9 to 30VDC ASIC Technology for High Reliability Lifetime Warranty Datasheet

The Ultra SlimPak Model G478 is a DIN rail mount, frequency input signal conditioner with 1800VDC isolation between input, output and power. The field configurable input and output offer flexible, wide ranging capability for variable frequency drives, magnetic pick-ups, turbine flow meters, and other pulse or frequency output transducers.

The input of the G478 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 G478 to be field configured for virtually any frequency input to DC signal output within the ranges specified. Calibration utilizes ‘Touch-Cal’ 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.

The very narrow Ultra SlimPak housing enables installations of up to 24 unit per linear foot. The wide ranging power supply is inverter isolated and accepts any voltage between 9 and 30VDC.
