The module performs the function of a high-voltage switch of analog signals and connects any of 200 independent output lines to the input lines forming an acting or measuring channel.

The module is designed for operation in measuring system as high-voltage switch of analog signals. VVK7 can connect any of the 200 independent output lines to input lines, forming a measuring channel or an excitation channel.

Module VVK7 expanded Informtest’s line of high-voltage relays switches, which provide automation of various tests in popular quality control and wiring harnesses test systems TEST-9110-VXI.



The main technical characteristics of the functional part
The module provides:
  • connection to the object of control of 200 output lines;
  • connection to any of 200 output lines of any of four input measuring lines: “Eo / Io”, “+ Ux”, “Ix / -Ux” and “-Io”
When the output line is connected to the input line, a channel is formed with the following characteristics:
  • maximum switching voltage (DC voltage value or AC voltage amplitude value) 1000 V;
  • maximum switching current 0.5 A;
  • maximum switched power 10 W;
  • maximum current flowing when the channel relay is in the closed state 1 A;
  • closing / opening time of a switching element (relay) not more than 1.1 ms.
The maximum voltage that can be applied between two input lines, between two output lines, between any input and any output line with open relay contacts between them, no more than:
  • 2100 V for direct current voltages;
  • 2120 V amplitude value (1500 V rms) for AC voltages
Insulation resistance between two input lines, between two output lines, between any input and any output line with open relay contacts between them at least 1 GOhm    The module provides the possibility of functional verification of the main nodes in the "Self-control" mode
Main technical characteristics of the interface part
The interface part of the module provides the following characteristics:
  • hierarchical properties - executor;
  • device class - based on registers (RB);
  • address space - A16 / A24;
  • data format - D32;
  • dynamic / static addressing of the VXI device;
  • model code module VVK7 - 18B h;
  • the required memory capacity is 8192 bytes;
  • electrical specifications in accordance with IEEE Std 1155-1992
