Description
The model Q403 is a fast response, 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 multi-channel signal conditioner (2 inputs/2
outputs).
Factory configured input and output ranges support bipolar
voltage signals (
20mA, 0-5 Volts, 0-10 Volts and 1-5 Volts. Front accessed zero and
span potentiometers allow 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 face plate, for right side or left side
mounting, respectively). The module to be attached will easily
slide on to the side of the mounted unit.

Operation
The Q403 operates as a four-wire transmitter; each channel
derives its power from an independent, transformer isolated, AC
to DC power source (85 to 265VAC).
The Q403 has fixed input/output ranges. The standard I/O ranges
in Tables 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 an AC source (between 85 and 256 VAC)
capable of providing up to 0.5 Amps.
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 -5/5V or -10/10V. Typically an industrial
control system such as a DCS or PLC requires standard industrial
control signals and 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 signals it requires. The four-wire transmitter
will increase the signal drive to high impedance loads and may
improve resolution of the process variable.
The 2000VAC isolation capability of the Q403 prevents ground
loops from causing errors in DC signals. Filtering and common
mode rejection are included to reduce susceptibility to EMI and
RFI. Isolation also provides protection from high voltages and
current spikes which can damage expensive Supervisory Control
and Data Acquisition (SCADA) equipment.
2. Set the calibrator to the specified minimum DC input value and
adjust the zero potentiometer for minimum (e.g. -10V) output.
3. Set the calibrator to the specified maximum DC input value and
adjust the span potentiometer for maximum (e.g. +10V) output.
4. Repeat steps 2 and 3 to validate calibration to the output load.
