Description
The 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 100mA, it is recommended that an input
shunt resistor be used and the Q466 be configured for the proper
input range. For example, a 5A current transformer output can use
the C006 shunt resistor (0.1 ohm, 5W) with the input of the Q466
set for 0-500mVAC.
The DC output of the Q466 is proportional to the average of the
fully-rectified AC input signal, and is calibrated for sine waves
between 40-400Hz.
TouchCAL
The Q466 utilizes TouchCAL technology which greatly simplifies
calibration. The thermal drift and mechanical variability of the
potentiometers has been removed and replaced with a digitally
stable circuit. Once the unit is configured via DIP switches for
voltage or current, the pushbutton is used to precisely calibrate
the minimum and maximum levels.
To set the input level within the dip switch configured range,
simply apply the high input signal (voltage or current) and push 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.

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 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.
Diagnostic LEDS
The Q466 has three diagnostic LEDs. The green (RUN) LED is used
for diagnostics to indicate that power is on. It will flash quickly if
the input signal is above the calibrated range or slowly if the input
signal is below range. It is on continuously when the unit is
functioning within the calibrated range.
The yellow (INPUT) LED is on while calibrating the input level. The
red (OUTPUT) LED is on while calibrating the output level.
Configuration
The Q466 can be configured for input ranges from 50mV to 300V
or 5mA to 100mA, with >90% input offset or it will adjust down
to <10% of full scale input span (except on the 100mV/10mA range
in which maximum offset or gain adjustment is 50%).
Unless a specific custom calibration is specified, the factory
presets the Q466 as follows:
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 pushbutton 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. Input ranges such as 180200V or 0-20V are possible using the 0-200V range.

Calibrated Output: 4-20mA

WARNING: Do not change switch settings with power applied.
Severe damage will result!
1. With power off, snap off the faceplate by lifting the right edge away
from the heatsink. Slide the heatsink forward and off the module.
2. Choose the desired range from Tables 1-3. Return the heatsink to its
original position and attach the faceplate before beginning calibration.
Note: To quit the calibration mode and reset the unit, push and
hold the CAL button for more than 5 seconds. Or, wait for more than
two minutes and the unit will timeout and automatically reset to
the previously stored calibration.
4. When the yellow and green LEDs stop flashing, the yellow and
red LEDs will be on. Push the CAL button momentarily (the yellow
and green LEDs will now be on).
Calibration
For best results, calibration should be performed in the operating
installation, allowing at least one hour for thermal stability of the
system. If pre-calibration on a test bench is preferred, then an output
load equal to the input impedance of the device connected to the
Q466 output is recommended, along with a 1 hour warm up period.
1. For best results install the module on to a piece of DIN rail or
the I/Q Rail mounting accessories if desired. See the I/Q Rail Data
sheet for details.
Note: An I/QRail is required to power the modules. See ordering
information.
2. Connect the input to a calibrated AC source and the output to
a voltage or current meter. Apply power and allow the system to
reach thermal equilibrium (approx. 20 minutes).
3. Adjust the input signal to the desired maximum and observe that
the green LED is on or flashing. Push the CAL button and hold it
down for more than 5 seconds (until the yellow and Green LEDs
are flashing), then release the button.

5. Apply the maximum input signal level desired and push the CAL
button to store. The yellow LED will now be on.
6. Apply the minimum input signal level desired and push the CAL
button to store. The green and red LED will now be on.
7. Adjust the input signal while monitoring the output signal until
the output is at the desired maximum level (e.g. 20.00mA), then
push the CAL button to store (the red LED will be on).
8. Adjust the input signal while monitoring the output signal until
the output is at the desired minimum level (e.g. 4.00mA), then push
the CAL button to store (the yellow, green and red LEDs will be on).
9. To finish calibration, push the CAL button once again. The green
LED will be on if the input is within the calibrated range.
