AC current converter DAT5023IAC.
GENERAL DESCRIPTION
The AC current converter DAT5023Iac is designed to detect the TRMS value of the AC current signal from 0÷5A to 0÷60 A applied on its input, providing a voltage or current output signal.
The user can program the input and output ranges by the DIP-switches located on the side of device.
The regulation of Zero and Span values is made by the ZERO and SPAN potentiometers located on the top of device.
The DAT5023Iac provides on the output side an auxiliary supply source to connect both active and passive loads.
The device is available in three versions (A, B and D).
DAT5023 Iac version A 0-5Amp, 0-10Amp.
DAT5023 Iac version B 0-20Amp, 0-25Amp, 0-30Amp.
DAT5023 Iac version C 0-40Amp, 0-50Amp, 0-60Amp.
The DAT5023Iac is accurate to 0.1% full scale and has less than 0.01%/'f thermal drift.
The 2000 Vac isolation between Input, power supply and output 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 DAT5023Iac provides a power supply on the output side so both active and passive loads can be connected.
The DAT5023Iac is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT5023Iac is housed in a plastic enclosure of 27.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.
USER INSTRUCTIONS
The converter DAT5023Iac must be powered by a direct voltage included in the 18 V to 30 V range. The power supply must be applied between the terminals Q
(+Vdc) and R (GND1). The green led PWR switched on shows the right state of supply of the device.
The output connections must be made as shown in the section "Output connections".
Voltage output: between the terminals N (Out) and M (GND2); passive current output: between the terminals P (Out) and M (GND2) for the sink currents;
active current output : between the terminals O (Vaux) and P (Out) for the source currents.
Connect the input cable inside the cross connector as shown in the section "Input connections".
The configuration of the input and output ranges values is made by DIP-switches (refer to the section “Input range tables” and “Output ranges table”).
After the converter configuration, it is necessary to calibrate it using the ZERO and SPAN regulations; this operation is illustrated in the section “DAT 5023Iac:
Configuration and calibration”.
To install the device refer to the section “Installation instructions”.
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
The DAT5023Iac 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 case:
- If panel temperature exceeds 45°C and at least one of the overload conditions exists.
- If panel temperature exceeds 35°C and at least two of the the overload conditions exist.
Overload conditions:
- High power supply values (> 27 Vdc).
- Use of current output (terminal P).
- Use of output auxiliary supply (terminal O ).
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
1) In function of the version of device, refer to the “Input range tables”, determine in the column " Input " the position of the input value. Refer to the “ Output ranges table " and determine in the column " Output" the position of the output value. In the correspondent lines is shown how to set the DIP-switches .
2) Set the DIP-switches as indicated .
3) Connect the input cable in the cross connector.
4) Set the minimum value of the input range.
5) By the ZERO potentiometer calibrate the output at the minimum value .
6) Set the maximum value of the input range.
7) By the SPAN potentiometer calibrate the output at the maximum value .
8) Repeat the operation from the step 4 to the step 7 until the output value
will be correct ( 3 attempts typically required).
