SYNCHRONOUS GENERATORS MEET THE REQUIREMENTS OF DIRECTIVE 2011/65/EU (ROHS, ROHS II) CONCERNING LIMITATION TO USE HAZARD SUBSTANCES (PB, HG, CD, CR(VI)) IN ELECTRICAL AND ELECTRONIC EQUIPMENT; THEY ARE MANUFACTURED USING LEAD-FREE METHOD, IN COMPLIANCE WITH THE EUROPEAN COMMUNITY REQUIREMENTS

Function

of Synchronous generator ZET 7090

Synchronous generator ZET 7090 is used for  signal forming of sinus, implulse and saw-tooth shapes and has 2 synchronous channels. Generators can be used independently or within automation and control systems.

Output channels control is performed by means of ZETLAB software or any other software using Modbus protocol.

Application spheres

of Synchronous generator ZET 7090

  • Control

    of heating elements

  • Measuring equipment calibration

    seismic stations, noise- and vibration meters and other measuring equipment calibration

  • Frequency response control

    by means of measuring modules – frequency response control with feedback communication

  • Vibration sensors and seismic recorders calibration

    by electrical method (in-place calibration) or by comparison method (vibration impact by means of shaker system)

Measuring network connection scheme

of Synchronous generator ZET 7090

In order to connect synchronous generator  ZET 7090 to ZETLAB and ZETVIEW systems one can use interface converter ZET 7070. Number of control modules connected to the interface converter ZET 7070 in the case if integrated power supply module ZET 7070 is used is maximum 4, in the case of external power supply module use – up to 60.

ZETLAB software enables connection of up to 1024 modules to a single PC. The control modules can also be connected to any system using Modbus protocol via interface RS-485.
