FEATURES 
Intrinsically safe, isolated universal input temperature Transmitter DAT1065IS with PC programmability
GENERAL DESCRIPTION
The intrinsically safe, isolated universal input temperature Transmitter DAT1065IS is a hockey puck (head mount) temperature Transmitter with PC programmability. The input can be K-Type Thermocouples, E-Type Thermocouples, J-Type Thermocouples, N-Type Thermocouples, R-Type Thermocouples, S-Type Thermocouples, T-Type Thermocouples. Pt100, Pt1000, Ni100, Ni1000 or mV and potentiometer. The DAT1065 will linearize the temperature input and provide a 4-20mA output signal.
The DAT1065IS is isolated between the input and power supply/output to 2000V and eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.
The DAT1065IS is accurate to 0.1% full scale and has less than 0.01%/'f Thermal drift.
The DAT1065IS 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 DAT1065IS is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT1065IS is housed in a self-extinguish plastic enclosure suitable for DIN B in-head mounting.
There is a mounting kit available to mount the DAT1065IS on DIN rail.
USER INSTRUCTIONS
The transmitter DAT1065IS must be powered by a direct voltage between 10 to 32 V and applied to the terminals +V and -V.
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 " DAT1065IS: configuration and calibration" and “Installation Instructions”.
1) The power supply voltage (intrinsically safe) applied between the terminals -V and +V 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
