The field configurable ActionI/Q Q466 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 100mAAC or 50mV to 300VAC.

For current inputs above 100mAAC, it is recommended that an input shunt resistor be used and the Q466 be configured for the proper input range. For example, a 5AAC current transformer output can use the Action model C006 shunt resistor (0.1W, 5W) and set the input of the Q466 for 0-500mVAC.

The DC output of the Q466 is proportional to the average of the fullyrectified AC input signal, and is calibrated for sine waves between 40-400Hz.

Low-cost microprocessor technology has enabled replacement of zero and span adjustment potentiometers with push-button, “TouchCALTM” technology. In essence, the thermal drift and mechanical variability of the potentiometers have been removed and replaced with a digitally stable circuit.

TouchCAL technology enables precise calibration and provides more than 90% offset of the zero value and adjustment down to 10% of the full scale input span for most of the 16 switch selectable input ranges. For example, the dipswitch configured 0-200V input range could be calibrated via push button for 0-80V (i.e. 60% span reduction) or offset to a range of 120-200V (i.e. 60% offset and 60% span reduction). If the output was configured for 0-10V, then 120- 200V input would correspond to the 0-10V full scale output. Thus, input ranges such as 180-200V or 0-20V are possible using the 0- 200V range.

Additionally, the inherent zero and span interactivity of potentiometer based analog amplifier circuitry is removed, providing 100% non-interactive adjustment

Advanced digital technology combined with Action’s exclusive ASIC technology allows the Q466 to be field configured for virtually any AC input to DC output within the limits specified.

Application
The ActionI/Q Q466 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 Q466 can drive a digital meter for direct display or can interface with alarm or control devices including PLCs and computers.

Touchcal Technology
The Q466 utilizes Action Instruments’ TouchCAL technology which greatly simplifies calibration. Once the unit is configured via DIP switches for voltage or current, the push-button is used to precisely calibrate the minimum and maximum levels.

To set the input level within the dip switch configured range, the user simply applies the high input signal (voltage or current) and pushes the CAL button. The low input signal is then applied and pushing the CAL button again stores the low input signal.

The high and low input levels are stored in nonvolatile memory and correspond to the high and low output levels. These output levels are precisely adjusted using the input signal.
