Ultra Slim Housing for High Density Installations

Flexible Power Supply Accepts 9 to 30VDC

The 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 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA.

The G478 to be field configured for virtually any frequency input to DC signal output within the ranges specified. Calibration utilizes ‘Touch-Cal’ technology in which the user simply applies the minimum and maximum input frequencies, and touches a recessed button to configure the corresponding minimum and maximum output range.

The Ultra SlimPak housing allows installation of up to 24 units per linear foot. The wide ranging power supply is inverter isolated and accepts any voltage between 9 and 30VDC.

Application
The G478 is useful in eliminating ground loops and interfacing pulse output transducers, such as turbine flow meters and magnetic pick-ups, to data acquisition and control systems.

Advanced digital technology, combined with Action’s ASIC technology, provide a stable output at low frequencies for higher accuracy.

Touch-CAL Technology
To precisely adjust the output, the user adjusts the input frequency while the OUTPUT LED is lit until the desired output level is achieved. The output levels are locked-in by pushing the CAL button. Status LEDs show the operation mode of the device.
