Q404-2L09 - EUROTHERM CONTROLS - Datasheet.Directory

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.
