Intrinsically safe, universal input Transmitter DAT2015IS High with PC programmability.
GENERAL DESCRIPTION
The universal Transmitter DAT2015IS is a Din Rail mount temperature/signal Transmitter with PC programmability. The input can be thermocouples, RTD, mA, V, mV, resistance and potentiometer. The DAT2015IS will linearize the temperature input and provide a 4-20mA output signal.
The DAT2015IS is accurate to 0.1% full scale and has less than 0.01%/'f thermal drift.
The DAT2015IS is programmable by PC based software which has been developed by DATEXEL to be user friendly.
For resistance and RTD's sensors it is possible to program the cable compensation for 3 or 4 wires.
It is possible to set the minimum and maximum values of the input and output ranges in any point of the scale, keeping the minimum span shown in the table below. Also high burn out alarm or low burn out alarm is selectable.
The DAT2015IS is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT2015IS is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
The DAT2015IS is able to measure and linearize the standard thermocouples with internal cold junction compensation.
Suitable for the following thermocouples.
K Type Thermocouples
J Type Thermocouples
S Type Thermocouples
R Type Thermocouples
B Type Thermocouples
E Type Thermocouples
T Type Thermocouples
N Type Thermocouples
Suitable for the following RTD.
Pt100
Pt1000
Ni100
Ni1000
USER INSTRUCTIONS
The 4÷20 mA output signal is measurable in the power loop as shown in the section “Output/Power supply connections”; Rload is the input impedance of instruments on the current loop; to obtain a correct measure, the value of Rload will be calculated as function of the power supply value ( see section “Technical specification – Load characteristic”).
The input connections must be made as shown in the section "Input connections".
To configure, calibrate and install the transmitter refer to sections " DAT2015IS: configuration and calibration" and “Installation Instructions”.
In order to guarantee a correct and safe operation of the transmitter the following requirements must be strictly satisfied
1) The power supply voltage (intrinsically safe) applied between the terminals M and N must be included between 11 V and 30 Vdc values.
2) The maximum power supplied by the safety barrier must be not higher than 0.75 W.
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
In order to guarantee the safety requirements, before to install the device, refer to the “Safety Instructions” provided with the device.
The transmitter must be mounted in order to guarantee to it an IP54 protection grade or more for external environments and an IP4X protection grade or more for internal environments or protected area.
The device DAT2015IS is suitable for DIN rail mounting.
It is necessary to install the device in a place without vibrations; avoid to routing conductors near power signal cables .

DAT2015IS: CONFIGURATION AND CALIBRATION
Warning: during these operations the device must always be powered by a safety barrier; to connect the interface Prodat, use the protection cable CVPR-03.
CONFIGURATION
1) Power-on the DAT2015IS by a safety barrier (see Ex data) .
2) Remove the protection plastic cap on DAT2015IS.
3) Connect the interface PRODAT to the Personal Computer and to device. using the protection cable CVPR03. (see section “DAT2015IS:
PROGRAMMING” ).
4) Run the software PROSOFT.
5) Set the parameters of configuration .
6) Program the device.
CALIBRATION CONTROL
With software PROSOFT running:
1) Connect on the input a calibrator setted with minimum and maximum values referred to the electric signal or to the temperature sensor to measure.
2) Set the calibrator at the minimum value.
3) Verify that the DAT2015IS provides on output the minimum setted value.
4) Set the calibrator at the maximum value.
5) Verify that the DAT2015IS provides on output the maximum setted
value.
6) In case of regulation of value obtained in the step 3 and 5, use the ZERO and SPAN regulators of software PROSOFT.
The variation introduced from these regulators must be calculated as
percentage of the input range .
7) Program the device with the new parameters .
