E-counters are used for the measurement of kWh in single-phase and three-phase systems, e.g. in industrial plants, offices and apartments in apartment houses. They help minimize operating costs and facilitate cost assignment.

E-counter with LCD

1) Large-size 7-digit LCD, 8 × 4 mm

2) IR readout interface for mounting the readout measuring head

3) Display pushbutton

4) IR test output LED (10 IMP./W)

5) Sealable Set/Reset pushbutton

Readout data for consumption analysis

Manual readout

The above data can be called up and manually displayed directly on the E-counter by pressing pushbuttons 5) Set/Reset pushbutton and 3) Display pushbutton. The E-counter calculates the consumption costs when the price per kWh has been entered. The ability to input the device number facilitates assignment to a number system and cost assignment to one of the various cost centers.

Readout software for the IR measuring head

The data of the following table are read into a PC using the magnetic IR measuring head and stored in an ASCII file in compliance with IEC 61107.

This ASCII file can be further processed in an Excel or Access file.

The product range can run under Windows 95, 98 and Windows NT.

Readout data on the LCD or over IR interface

x = data are displayed

Data transmission instabus KNX

The 7KT1 162 and 7KT1 165 counters are intended for the following data transmission:

Active energy (kWh) rate 1
Active energy (kWh) rate 2
Device number
Active power (kW) phase L1
Active power (kW) phase L2
Active power (kW) phase L3

Visualization software "Recording of consumption data and maximum time analysis" (available soon)

The software can read out and assign counter readings, and prepare the data for accounting.

The system does not differentiate between counters that are read out manually or in online operation.

A maximum time analysis can be carried out over several days on the PC in online operation. Graphical analyses are also available.

Energy flow direction

Counting is only carried out in the specified energy flow direction. For counters with transformer connection, the energy flow direction of the transformer (primary and secondary) as well as the correct assignment of the voltage and current paths must be taken into account.

Схема подключения

S0 interfaces

Connection with S0 interface

The short-circuit resistant optocoupler is operated at 5 ... 30 V DC. The current must be selected within a range of max. 20 mA. The pulse duration is 125 ms.

Instructions for the connection of transformer counters
In the case of cross-section reduction, a short-circuit resistant cable is required for the power supply of terminals 2, 5 and 8, depending on the fusing for phases L1, L2, L3. A 6 A fuse is recommended for the line protection.

Direct connection 10 (63) A

Transformer connection 5 (6) A
