Isolated universal Converter, Splitter and Trip Amplifier DAT4530 configurable by Dip-Switch or PC with option of SQRT extraction.
GENERAL DESCRIPTION
The isolated universal Converter DAT4530 is a Din Rail mount signal Converter, Splitter and Trip Amplifier with PC programmability. The input can be thermocouples, RTD, mA, V, mV, resistance and potentiometer. The DAT4530 will linearize the input and provide a 4-20mA passive or active output signal or a voltage output signal.
The DAT4530 is accurate to 0.1% full scale and has less than 0.01%/'f thermal drift.
The DAT4530 is programmable by Dip Switch or 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 DAT4530 is isolated between the power supply and the input/output to 1500V, eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.The DAT4530 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
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
The DAT4530 is housed in a plastic enclosure of 22.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
The DAT4530 is able to measure and linearize the standard thermocouples with internal cold junction compensation.
DAT4530 is a Converter and Splitter with an output trip alarm.
For mV, V and mA input it is possible to set an option for the fast sampling (option HS) or to extract the square root of the measured signal (option SQRT).
The 1500 Vac galvanic isolation on all ways (input, outputs and power supply) eliminates the effects of all ground loops eventually existing and allows the use of the converter in heavy environmental conditions found in industrial applications. The DAT4530 is in compliance with the standard 89/336/EEC on the Electromagnetic Compatibility. It 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.
USER INSTRUCTIONS
The converter must be powered by a direct voltage applied to the terminals U and V. The analogue channel measures the value from the sensor connected to the terminals C-D-E-F-G-H-I-L and transmits the output measures on the terminals M-N-O-P (OUT A) and the terminals Q-R-S-T (OUT B). A contact for the trip alarm is available on the terminals A-B. The input and output connections must be made as shown in the section "Connections". It is possible to configure the converter on field by dip-switch or Personal Computer as shown in the section “ Programming ". The configuration by dipswitches can be made also if the device is powered (note: after the configuration the device takes some seconds to provide the right output measure ).
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
The device is suitable for fitting to DIN rails in the vertical position. For optimum operation and long life follow these 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 high power supply value ( > 27 Vdc ). - Use of one or both current outputs. - Use of active current input. Make sure that sufficient air flow is provided for the device avoiding to place raceways or other objects which could obstruct the ventilation slits. Moreover it is suggested to avoid that devices are mounted above appliances generating heat; their ideal place should be in the lower part of the panel. Install the device in a place without vibrations. Moreover it is suggested to avoid routing conductors near power signal cables (motors, induction ovens, inverters etc...) and to use shielded cable for connecting signals.
THRESHOLD OPERATION
HIGH ALARM THRESHOLD
For the high alarm the relay goes on when the input signal is higher than the trip level and after the delay time. The relay goes off only when the input signal is lower than the trip level minus the hysteresis value or when reaches the minimum value of the input scale and after the delay time.
LOW ALARM THRESHOLD
For the low alarm the relay goes on when the input signal is lower than the trip level and after the delay time. The relay goes off only when the input signal is higher than the trip level plus the hysteresis value or when reaches the maximum value of the input scale and after the delay time.
PROGRAMMING
CONFIGURATION BY PC
By software DATESOFT it is possible to: - set the default programming of the device; - program the options not available with the dip-switch; (burn-out level, CJC offset, trip alarm settings, fast sampling, etc...); - read, in real time, the input and output measures; - follow the dip-switches configuration wizard. To configure the device follow the next steps:
1) Power-on the device.
2) Open the protection plastic label on the front of the device.
3) Connect the interface PRODAT to the PC (COM port) and to the device (PGRM connector).
4) Open DATESOFT.
5) Select the COM port in use.
6) Click on “Open COM”.
7) Click on the icon “Program”.
8) Set the programming data.
9) Click on the icon “Write” to send the programming data to the device. Warning: during these operations the device must always be powered and the TX/RX cable always connected. For information about DATESOFT refer to the software's user guide.
DIP SWITCH SETTINGS
CONFIGURATION BY DIP-SWITCHES
1) Open the suitable door on the side of the device.
2) Set the input type by the dip-switch SW1 [1..5] (see TAB.1)
3) Set the output A type by the dip-switch SW1 [7..8] (see TAB.2)
4) Set the output B type by the dip-switch SW2 [1..2] (see TAB.2)
5) Set, if available, the input option by the dip-switch SW1 [6] (see TAB.3)
6) Set the maximum input value (Full scale) by the dip-switch SW2 [3..8] (see TAB.4)
7) Set the minimum input scale value (Zero) by the dip-switch SW3 [1..4] (see TAB.4)
NOTE:
- It is also possible to set the dip-switches using the wizard of the configuration software following the procedure described in the section ”Configuration by PC” until the step 6 and clicking on icon “Switch”.
NOTES: * To set the input range refer to the TAB.4 (next pages) referred to the input type selected by the TAB.1. * If the dip-switches SW1 [1..5] are all set in the position 0 (“EPROM”), the device will follow the configuration programmed by PC ( input type and range, output type and range, trip alarm 's settings and options). * If the dip-switches SW2 [3..8] and SW3 [1..4] are all set in the position 0 (“Default”), the device will follow the input scale programmed by PC for the input type selected by the dip-switches SW1 [1..5] * Eventual wrong dip-switches settings will be signalled by the blinking of the led “PWR”. * If the dip-switch SW1 [6] is set in the ON position and is in progress a measure by Resistance or RTD 2 wires sensor, it is necessary to connect the terminal I to the terminal L and the terminal G to to the terminal H.
