Isolated Frequency Converter DAT4540 configurable by Dip-Switch or PC, Transistor or Relay Outputs.

GENERAL DESCRIPTION

The Isolated Frequency Converter DAT4540 is able to measure, up to 20 KHz. The input may be from TTL, Namur, NPN, PNP and Tachometer digital signals.It is programmable by PC or DIP Switches. The output can be both passive current or active current, and voltage. The DAT4540 also provides 3 digital outputs.

The DAT4631D is accurate to 0.1% full scale and has less than 0.02%/'f thermal drift.

The DAT4631D is isolated between the power supply and the input/output to 1500V and eliminates the effects of any ground loops and allows the use of the transmitter in heavy environmental conditions found in industrial applications.

The DAT4631D is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.

The DAT4631D 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 Q and R.

The analog channel measures the value from the sensor connected to the terminals the I, L, G, H and transmits the output measure on the terminals N, M, O and P.

The connections for the trip alarms are available between th terminals A-B-C-D and S-T-U-V (version -R); the digital contact (N.C.) of the Fault alarm for the Namur sensor is available between the terminals E-F. 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 and the device is powered with high power supply value ( > 27 Vdc ).

- Use of output active current.

- Use of the input auxiliary supply .

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.

PROGRAMMING

CONFIGURATION BY PC

By software DATESOFT 2.5 and later releases 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, 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 DATESOFT2.5 .
5) Select the COM port in use.
6) Click on “Open COM”.
7) Click on “Program”.
8) Set the programming data.
9) Click on “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.

CONFIGURATION BY DIP SWITCH

1) Open the suitable door on the side of the device.

2) Set the input type by the dip-switch SW1 [1..2] (see TAB.1)

3) Set the output type by the dip-switch SW1 [3..4] (see TAB.2)

4) Set the input Full Scale value by the dip-switch SW2 [1..6] (see TAB.3)

5) Set the multiplication factor by the dip-switch SW2 [7..8] (see TAB.3)
