The ActionI/Q model Q406 is an AC powered,
DIN rail mount, DC input signal conditioner, with 1800V isolation between
input, output and power. The field configurable input and output feature offers
flexible, wide ranging capability for DC current and voltage signals.
Advanced technology has added two significant
improvements to this new DC to DC signal isolator.
First, advances in surface mount design and
switching power supply technology allow multi-channel density. The Q406 is
available as a single channel signal conditioner (1 input / 1 output) or as a
multi channel signal conditioner (1 input / 2 outputs, or 2 inputs / 2
outputs). All models maintain the high 1800V isolation level from channel to
channel, as well as input to output to power.
Second, low-cost microprocessor technology
has enabled replacement of zero and span adjustment potentiometers with
push-button, TouchCAL technology. In essence, the thermal drift and
mechanical variability of the potentiometers have been removed and replaced
with a digitally stable circuit. Additionally, the inherent zero and span
interactivity of analog amplifier circuitry is removed, providing 100%
non-interactive adjustment.
The field configurable input of the Q406 can
be set via DIP switches for any one of 12 voltage ranges from 20mV to 100V or 6
current ranges from 2mA to 100mA (see Table 1). The field configurable output
is linear to the input and can be set for either 0-5V, 0-10V, 0- 1mA, or
4-20mA. TouchCAL Technology enables precise calibration, providing more than
90% offset of the zero value and adjustment down to 10% of the full scale input
span for each of the 18 switch selectable input ranges. For example, the DIP
switch configured 0- 20mA input range could be calibrated via push button for
0-8mA (i.e. 60% span reduction) or offset to a range of 12-20mA (i.e. 60%
offset and 60% span reduction). If the output was configured for 0-10V, then
12-20mA input would correspond to the 0-10V full scale output. Thus, input
ranges such as 18-20mA or 0- 2mA are possible using the 0-20mA range.
Advanced digital technology combined with
Actions ASIC technology allows the Q406 to be field configured for
virtually any DC input to DC output within the limits specified. Calibration
utilizes TouchCAL technology where the user simply configures the
input for the current or voltage range via switches, then follows the
Calibration Flow Chart. The output is set by adjusting the input until the
desired output is present and then pressing the CAL button to store the output
level.
An optional feature of the Q406 is a 24VDC
excitation source (20mA max.) common to the input and isolated from AC power.
This can power a two-wire transmitter or a three-wire transducer. The Q406 will
accept power between 85 to 265VAC. |
