Hazardous Area Current Loop Isolataor, Loop Repeater DAT5030 IS A.
GENERAL DESCRIPTION
The Loop Isolater Loop Repeater DAT5030ISBH device is a galvanically isolated, Intrinsic Safety Barrier, defined as “Associated Apparatus”
Inputs
- 4-20 mA Active Current Loop
- 4-20 mA Passive Current Loop
- 0-20 mA Active Current Loop
- 0-20 mA Passive Current Loop
Outputs
- 4-20mA Active Current Loop
- 4-20mA Passive Current Loop
- 0-20mA Active Current Loop
- 0-20mA Passive Current Loop
- 0-10 Volts
- 2-10 Volts
Auxiliary power supply is available to supply the current loop connected to the output.
The input and output range can be set by means of the dip-switch available on the side of the enclosure (see configuration table). The calibration of the device can be made by means of trimmer (ZERO and SPAN) available on the side of the enclosure.
DAT5030IS has a 3 way isolation: input (connected to hazardous area devices) is 2000 Vac isolated from power supply and output (connected to safe area); power supply and output are 1500 Vac isolated between them.
The device must be powered with a voltage between 20 to 30 Vdc; the “PWR” green led turned on indicate the correct power supply.
The DAT5030IS /A model is single channel.
The DAT5030 IS /B model is a dual channel.
The DAT 5030IS /AH is a single channel with HART.
The DAT 5030IS /BH is a dual channel with HART.
The HART models (single and dual channel) are capable of transferring the bidirectional HART signal between input and output.
The DAT5030IS current loop repeater/supply, developed, manufactured and tested in strict accordance with the quality assurance standard UNI EN ISO 9001/2000, is in compliance with the directive 89/336/CEE on the electromagnetic compatibility.
The device is housed in a rough self-extinguish plastic case suitable for DIN rail mounting of 22.5mm thin profile.
TECHNICAL SPECIFICATIONS
INSTALLATION INSTRUCTIONS
To guarantee the Safety characteristics, before to install the device read the relative “Safety Instructions” supplied with them.
The DAT 5030 IS device is suitable for fitting to DIN rails in the vertical position.
For optimum operation and long life, follow the instructions above.
When devices are installed side by side, it may be necessary to separate them by at least 5mm in the following case:
- If panel temperature exceeds 45°C and at least one of the overload conditions exist.
- If panel temperature exceeds 35°C and at least two of the overload conditions exists.
The overload conditions are the following:
- High supply voltage: >27Vdc
- Use of the auxiliary power supply (terminal 4-14-D-O)
Make sure that sufficient air flow is provided for the device avoiding to place racewais 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.
It is recommended to use shielded cable for connecting signals. The shield must be connected to an earth wire provided for this purpose. Moreover it is suggested to avoid
routing conductors near power signal cables (motors, induction ovens, inverters etc...).
PROGRAMMING
Input and output configuration is made by means of DIP switch available on the side of the
enclosure. The configuration table show the available signal configurations indicating the
proper dip-switch configuration. After the configuration of the device, it must be calibrated
by means of ZERO and SPAN regulation availables near the dip-switch.
The two channels of DAT 5030 IS /B and DAT 5030 IS /BH models have independent
configuration and calibration.
