FEATURES
- Input from Pt100
- Input scale in °C or °F
- Zero and Span programmable by DIP-switches
- 4÷20 mA current loop linearised output
- Good accuracy and linearity
- EMC compliant – CE mark
- Suitable for DIN B in-head mounting
- Option for DIN rail mounting in compliance with EN 50022 (DIN RAIL Option)
GENERAL DESCRIPTION
The transmitter DAT 1111 is designed to provide on output a 4÷20 mA current loop linearised signal proportional with the temperature characteristic provided
from the Pt100 connected to its input.
It is possible to connect on input both Pt100 3 wires and Pt100 2 wires sensors.
It is possible to program the input range by the 4 way DIP-switches available removing the protection plastic cap located on the top of device (see the section
"Input ranges table").
The regulation of the zero and full-scale value are made using the ZERO and SPAN potentiometers.
The DAT 1111 is in compliance with the Directive 2004/108/EC on the Electromagnetic Compatibility.
It is housed in a self-extinguish plastic enclosure suitable for DIN B in-head mounting.
Moreover ( by proper mounting kit ) it is possible to mount the DAT 1111 on DIN rail.
USER INSTRUCTIONS
The transmitter DAT 1111 must be powered by a direct voltage between 10 to 32 V 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 " Load
characteristic").
The input connections must be made as shown in the section "Input connections".
The Pt100 three wires must be connected to the terminals 1 and 3, connecting the third wire to the terminal 2.
The Pt100 two wires must be connected to the terminals 1 and 3, connecting the terminal 2 and 3.
The configuration of the input range must be made by DIP-switches. To configure the device refer to the section "Input ranges table".
Regulate the output value by the ZERO and SPAN regulations.
To calibrate and install the transmitter refer to sections " DAT1111: configuration and calibration" and "Installation Instructions".
