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.

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.
