GENERAL DESCRIPTION
T e isolated double c annel converter DAT 4532 C is able to measure and linearise t e standard PTC and NTC sensors and potentiometers. 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 double c annel allows t e ig density mounting w ere is necessary to reduce t e encumbrances.
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 c annels wit two independent settings.
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 (inputs, 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 4532 C 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 c annel A measures t e value from t e sensor connected to t e terminals I, L and G and transmits t e output measure on t e terminals N and M.
T e c annel B measures t e value from t e sensor connected to t e terminals E, F and H and transmits t e output measure on t e terminals P and O.
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 ).
