ULTRA SLIMPAK(R) G468-0001 AC Input Field Configurable Isolator Provides an Isolated DC Output in Proportion to an AC Input G468-0001 Field Configurable Input Ranges: 50mV to 250VAC, 5mA to 5A AC Eliminates Ground Loops Field Configurable Outputs: 0-5V, 0-10V, 0-1mA, 0-20-mA and 4-20mA Description The G468 is a DIN rail mount, AC input signal conditioner with 1800VDC isolation between input, output and power. The field configurable input and output offers flexible, wide ranging capability for scaling, converting or buffering AC inputs ranging from 5mA to 100mA or 50mV to 250V. For AC current measurements above 100mA, use the model C006 shunt resistor (0.1 Ohm, 5Watt). This resistor must be wired in series with the current source, with the G468 configured to measure the voltage generated across the resistor (see Figure 3 for an example). The DC output of the G468 is proportional to the average of the fully-rectified AC input signal, and is calibrated for sine waves between 40-400Hz. Application The G468 is useful in applications requiring an isolated, conditioned DC output from an AC signal. Typical applications include energy management, load shedding, motor current/load monitoring, locked rotor detection, isolation and data acquisition. The output of the G468 can drive a digital meter for direct display or it can interface with alarm or control devices, including PLCs and computers. Diagnostic LED The G468 is equipped with a dual function LED signal monitor. The green, front mounted LED indicates both DC power and input signal status. Active DC power is indicated by an illuminated LED. If the input signal is more than 110% of the full scale range, the LED will flash at 8Hz. Below -10%, the flash rate is 4Hz. Ultra Slim Housing for High Density Installations Flexible Power Supply Accepts 9 to 30 VDC ASIC Technology for Enhanced Reliability RoHS Compliant Configuration The G468 has 15 input range switch settings. Trim potentiometers allow 50% input zero and span adjustablity within each of the 15 fullscale, input ranges. Since the unit has 50% adjustability, it can be ranged so that any 100 volt input span can create the full output (e.g., 25 to 125Vac = full output). Unless otherwise specified, the factory presets the Model G468 as follows: Input Range: Output: 0-500mVAC 4-20mA The DC power input accepts any DC source between 9 and 30V; typically a 12V or 24VDC source is used (see Accessories). Refer to Tables 1 through 3 for the proper switch settings. With power disconnected, use the switches (9 & 10) on SW1 to select the input type (voltage or current), on SW2 to select the desired output ranges, and (1-8) on SW1 to select the desired input range. WARNING: Do not change switch settings with power applied. Severe damage will result! Calibration 1. After configuring the DIP switches, connect the input to a calibrated AC source. Connect the output to the device (or a load approximately equivalent to the device) and apply power. Refer to the Terminal Wiring Diagram (Figure 2). Note: To maximize thermal stability, final calibration should be performed in the operating installation, allowing approximately 1 to 2 hours for warm up and thermal equilibrium of the system. 2. Set the calibrator to the desired minimum and adjust the zero potentiometer for the desired minimum output. 3. Set the calibrator to the desired maximum and adjust the span potentiometer for the desired maximum output. 4. Repeat steps 2 and 3, if necessary for best accuracy.
