Description
The model Q404 is a DIN rail mount, DC input signal conditioner,
with 2000VAC isolation between input output and power. It 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).
Factory configured input and output ranges support standard
industrial control signals such as 4-20mA and 0-10V. Front
accessed zero and span potentiometers allow 50% adjustment of
offset and gain to compensate for sensor errors or signal losses.
All ActionI/Q modules feature SnapLoc plug-in screw terminals for
easy installation . Two or more modules can slide together and
interlock for solid, high density mounting (remove either the DIN
rail foot or the adjacent unit’s faceplate, for right side or left side
mounting, respectively). The module to be attached will easily
slide onto the side of the mounted unit.
Application
DC input four-wire transmitters are used to isolate and convert DC
voltage or current signals into proportional, standard industrial
control signals such as 4-20mA or 0-10V. Typically an industrial
control system such as a DCS or PLC requires standard industrial
control signals with full isolation to ensure reliable, strong signals.
In most industrial process control or data acquisition applications,
several different input sources, including voltages and currents
from various field instruments (e.g. level, flow, pressure and
position sensors), are common. Four-wire transmitters accept
these field inputs and provide the controller (DCS & PLC) with the
standard industrial signal it requires. The four-wire transmitter
will increase the signal drive to high impedance loads and may
improve resolution of the process variable.

Operation
The ActionI/Q model Q404 operates as a four-wire transmitter;
each channel derives its power from an independent, transformer
isolated DC power source (10.8 to 26.4VDC).
The Q404 has fixed input and output ranges. The standard input
and output ranges shown in Table 1 are calibrated to rated
accuracy. One range per module; two channels per module,
maximum.
Calibration
Note: For best results, calibration should be performed with the
intended output load, in the operating environment, mounted on
a DIN rail, allowing at least one hour for thermal equilibrium of the
system.
1) To check calibration, connect the input to a calibrated DC
source. Connect the output to a DC voltage or current meter and
the input power to a DC source (10.8 to 26.4VDC) capable of
providing up to 0.5 Amps.
2) Set the calibrator to the specified minimum DC input value and
adjust the zero potentiometer for minimum (e.g. 4mA) output.
3) Set the calibrator to the specified maximum DC input value and
adjust the span potentiometer for maximum (e.g. 20mA) output.
4) Repeat steps 2 and 3 to validate calibration to the output load.
