SIMEAS TDigital Transducer

The SIMEAS T universal transducer allowsmeasurement of all electrical quantities oc-curring in any network in a single unit. Es-pecially in power plants and substationstransducers are used for isolation of elec-trical signals and for further processing ofmeasured values. Any desired measuredvalue (current, voltage, active power, fre-quency, etc.) can be assigned to each of the3 analog outputs, as well as any desiredmeasuring range.

The output signal (e.g. -10 to 0 to 10 mA,± 20 mA, 4 to 20 A, 0 to 10 V, etc.) can befreely parameterized for every outputchannel. The binary output can be used asa kWh meter to register the energy or as alimit monitor.

Input currents up to max. 10 A or inputvoltages up to 600 V with rated frequenciesof 16 2/3, 50 or 60 Hz can be connected.

The SIMEAS T is available with anRS232 or an RS485 interface. The devicecan be installed for operation on anIEC 60870-5-103 bus.

The unit can be reparameterized with theSIMEAS T PAR software package.

• SIMEAS T PAR - Parameterization soft-wareSlMEAS T digital transducers withRS232 or RS485 interface can beparameterized or calibrated with the PCsoftware SIMEAS T PAR. The measuredquantities can be displayed online on thePC via a graphical meter or can be re-corded and stored over a period of up toone week. The SIMEAS T PAR softwareenables the self-parameterization of thedigital transducer according to the de-sired parameter setting.

• SIMEAS T EVAL - Evaluation softwareUsing the SIMEAS T EVAL evaluationsoftware, the previously stored valueswith SIMEAS T PAR can be edited, eval-uated and printed in the form of agraphic or table.

Selection of measuring and metering quan-tities

Depending on the type of connection, thetransducer generally calculates all mea-sured or metered values marked with ●.Of these, any 3 measured variables ▼ canbe connected to the 3 analog outputs andany measured parameter ■ to the limitmonitor or for work metering to the bi-nary output.

RS232 and RS485 SIMEAS T transducer withinterface acc. to IEC 60870-5-103

In terms of their design, method of con-nection and technical data, the transducerswith an RS485 interface are identical to thestandard units with an RS232 interface. In-stead of the RS232 interface, however, aninterface conforming to EAI RS485 isinstalled for operation on anIEC 60870-5-103 bus. Thus, the transduc-ers are bus-compatible and, as shown inthe examples, can be networked.

Bus operation does not have an influenceon the output of analog measured quanti-ties via the analog outputs. The units areparameterized with the SIMEAS T PARsoftware.

Parameterization

Fig. 13/80

for universal transducer with RS485 interface

The transducers do not contain any me-chanical setting controls. This is why theunits must be adjusted for their tasks usinga PC or a notebook, the SIMEAS T PARsoftware and the RS232/RS485 converterprior to use on the bus. To this end, thetransducer must be connected to auxiliarypower and the RS232/RS485 converter bymeans of the included plug-in power sup-ply unit.

The following are parameterized:

Bus address: 1 to 254

Baud rate: 2400, 4800, 9600 or 19200 bits/s

Basic parameters: mains type, mains frequency, instrumenttransformer data

Bus mode: acc. to IEC 60870-5-103,with 9 or 16 measured values

Analog outputs: same as standard units (if required)

Binary output: same as standard units (if required)

Design In the case of 3-channel current transduc-ers, for example, only the 3 current inputsneed to be connected; in the case of3-channel voltage transducers, only thevoltage inputs need to be connected and,for frequency, for example, only the volt-age inputs L1-N need to be connected. Theunit can only be connected to one networkor feeder.

Connection examples SIMEAS T connectedto a network

The input circuits shown are only exam-ples. Connection without current and volt-age transformers is also possible up to themaximum current and voltage values.Voltage transformers can also be con-nected in a star or V connection.

Parameterization software

Description

By means of the SIMEAS T PAR software,SIMEAS T transducers with an RS232 oran RS485 interface can be parameterized orcalibrated swiftly and easily. Measuredquantities can be displayed on the PC on-line via a graphical meter or can be re-corded and stored over a period of up toone week.

Generally, all the transducers are alreadycalibrated and factory set when delivered.

Recalibration of the transducers is nor-mally only necessary after repairs or in theevent of readjustment.

Features

• Extremely simple and straightforwardoperation

• Storage of parameterization data under auser-defined name even without thetransducer

• Parameters are sent to transducers evenafter installation on the site

• A parameterization list with the specificconnection diagram of the transducercan be printed

• A self-adhesive data plate can be printedand fixed to the transducer, including apossibility of entering three lines of textcontaining the name and location etc.

Parameterization serves to set the trans-ducer to the required measured quantities,measuring ranges and output signals etc.Users are able to parameterize the trans-ducer themselves in only a few steps.

Communication

Communication with the transducer isachieved by means of a connecting cable(optionally available) connected via the in-terface that is available on every PC or lap-top. For units with an RS232 interface, usethe connecting cable 7KG6051-8BA or, forunits featuring an RS485 interface, use theconverter 7KG6051-8Ex. Three mutuallyindependent program sections can becalled up.

Reading out data

With graphical instruments, all measuredquantities calculated in the transducer andpower quantities can be displayed onlineon a PC or laptop, and either in analog ordigital form.

To improve the resolution of the graphics,users can freely choose the number of in-struments on the screen and can freely as-sign the measured quantity and measuringrange.

These are selected and assigned independ-ently of the unit’s analog outputs.

Displayed measured values can be stored,printed or recorded for the SIMEAS T EVALevaluation software.
