1. Safety instructions

1.1 Symbols

The symbols in these instructions point out risks and have the following meaning:

Smooth and safe operation requires that these operating instructions be read

and understood!

Warning in case of risks.

Non-observance can result in malfunctioning.

Non-observance can result in malfunctioning and personal injury.

Information on proper product handling.

1.2 Intended use

• The purpose of the SINEAX TVD825 isolating ampliﬁ er is to galvanically isolate input signals

from output signals, to amplify them and/or transform them to another level or another

signal type (current or voltage).

• The device is intended for installation in industrial plants and meets the requirements of

EN 61010-1.

• Manufacturer is not liable for any damage caused by inappropriate handling, modiﬁ cation or

any application not according to the intended purpose.

1.3 Commissioning

• Installation, assembly, setup and commissioning of the device has to be

carried out exclusively by skilled workers.

• Observe manufacturer’s operating instructions. Do not operate the device

outside of the limit values stated in the operating instructions. Check all

electric connections prior to commissioning the plant.

• Safety measures should be taken to avoid any danger to persons, any

damage of the plant and any damage of the equipment due to breakdown

or malfunctioning of the device.

• Decommission the device if its safe operation is no longer possible (e.g. in

case of visible damages). Disconnect all connections. Send the device to

our plant or to one of our authorised service centres.

1.4 Repair work and modiﬁ cations

Repair work and modiﬁ cations shall exclusively be carried out by the manufac-

turer. In case of any tampering with the device, the guaranty and warranty claim

shall lapse. We reserve the right of changing the product to improve it.

1.5 Disposal

The disposal of devices and components may only be realised in accordance

with good professional practice observing the country-speciﬁ c regulations

(applicable within the European Union and other European countries with a

separate collection system).

1.6 Transport and storage

Transport and store the devices exclusively in their original packaging. Do not

drop devices or expose them to substantial shocks.

3. General features

• Input of voltage, current, temperature (RTD, TC) or resistance

• Power supply of the sensor for current input (max. 17 V DC)

• Measurement on galvanically isolated output for voltage and active/passive current.

• Selection of input and output type, START/END for the selected input and output type by

means of DIP switches.

• Indication of available power supply and of alarm state via LED.

4.4 Environmental conditions

Operating temperature -10…+65 °C

Storage temperature -20…+85°C

Humidity 30...90 % at 40 °C (non-condensing)

Degree of pollution 2

Area of application Indoor areas up to 2000 m above sea level

4.5 Regulations

The device complies with

the following standards:

EN 61000-4-5 Class 2 (Surge protection of inputs, outputs/

power supplies)

EN 61000-6-4/2002 EN 61000-6-4/2002 (Electromagnetic inter-

ference, industrial environments)

EN 61000-6-2/2005 (Electromagnetic compatibility,

industrial environments)

EN 61010-1/2001 (Safety)

All circuits have to be insulated with double insulation against

circuits carrying hazardous voltage. The power supply transformer

has to comply with the speciﬁ cations of EN 60742: Isolating and

safety transformers

5. Mounting instructions

The signal converter is designed to be mounted on rails according to DIN 46277.

Mounting of signal converter

on the rail

1. Place the signal converter onto the top

part of the rail.

2. Press the signal converter downwards.

Removing the signal converter

from the rail

1. Use a screwdriver (as shown in the

ﬁ gure) as a lever.

2. Turn the signal converter downwards.

For optimum function and longevity, ensure adequate ventilation of the signal.

We recommend installation in vertical position. Avoid installing the signal

converter above devices generating heat. We recommend installing it at the

bottom of the switch cabinet.

6. Installation instructions

6.1 Input selection

The input type is selected by setting the DIP switch group SW1 1 to 5.

Select the start of scale for the measuring input using DIP switches 6, 7 and 8 of switch group SW1.

Select the end of scale for the measuring input using DIP switches 6, 7 and 8 of switch group SW2.

Note for all tables:

The symbol indicates that the DIP switch is in ON position.

No entry means the DIP switch is in OFF position!
