GENERAL DESCRIPTION
T e isolated doubler/converter DAT 4631 B is able to measure and linearise t e standard RTDs and resistances wit 2 or 3 wires cable compensation .
In function of programming, t e measured values are converted in a current or voltage signal. T e device guarantees ig accuracy and performances
stability bot versus time and temperature.
T e programming is made by t e dip-switc located in t e window on t e side of t e enclosure. By means of dip-switc es it is possible to select t e input
type and range and t e output type wit out recalibrate t e device.
Moreover, by Personal Computer t e user can program all of t e device's parameters for is own necessity; t e configuration by PC allows to program
t e two outputs wit two independent settings. For all t e sensors it is possible to set t e cable compensation wit 2 or 3 wires.
Moreover it is available t e option of alarm for signal interruption (burn-out) t at allows to set t e output value as ig or low out of scale .
T e 1500 Vac galvanic isolation on all ways (input, outputs and power supply) eliminates t e effects of all ground loops eventually existing and allows t e
use of t e converter in eavy environmental conditions found in industrial applications.
T e DAT 4631 B is in compliance wit t e Directive 2004/108/EC on t e Electromagnetic Compatibility.
It is oused in a plastic enclosure of 12.5 mm t ickness suitable for DIN rail mounting in compliance wit EN-50022 and EN-50035 standards.
USER INSTRUCTIONS
T e converter must be powered by a direct voltage applied to t e terminals Q and R.
T e analog c annel measures t e value from t e sensor connected to t e terminals t e I, L and G and transmits t e output measures on t e terminals N
and M (OUT A) and t e terminals P and O (OUT B).
T e input and output connections must be made as s own in t e section "Connections".
It is possible to configure t e converter on field by dip-switc or Personal Computer as s own in t e section “ Programming ". T e configuration by dip-
switc es can be made also if t e device is powered (note: after t e configuration t e device takes some seconds to provide t e rig t output measure ).

NOTES:
* For all t e input type selected by dip-switc es, t e compensation of wires is
fixed at 3.
* To configure t e range for t e input type selected (TAB.1) refer to t e section
of t e TAB.3 on next page relative to it (ex: for Pt100 use t e table TAB.3c ).
* If t e dip-switc es SW1 [1..4] are all set in t e position 0 (“EPROM”), t e
device will follow t e configuration programmed by PC ( input type and range,
output type and range and options).
* If t e dip-switc es SW1 [5..8] are all set in t e position 0 (“Default”), t e
device will follow t e input scale programmed by PC for t e input type
selected by t e dip-switc es SW1 [1..4]
* Eventual wrong dip-switc es settings will be signalled by t e blinking of t e
led “PWR”.

INSTALLATION INSTRUCTIONS
T e device is suitable for fitting to DIN rails in t e vertical position.
For optimum operation and long life follow t ese instructions:
When the devices are installed side by side it may be necessary to
separate them by at least 5 mm in the following cases:
- If panel temperature exceeds 45°C.
- Use of ig power supply value ( > 27 Vdc ).
- Use of output current.
Make sure t at sufficient air flow is provided for t e device avoiding to
place raceways or ot er objects w ic could obstruct t e ventilation slits.
Moreover it is suggested to avoid t at devices are mounted above
appliances generating eat; t eir ideal place s ould be in t e lower part
of t e panel.
Install t e device in a place wit out vibrations.
Moreover it is suggested to avoid routing conductors near power signal
cables (motors, induction ovens, inverters etc...) and to use s ielded
cable for connecting signals.
