VVK5 performs the function of a high-voltage switch of analog signals and connects any of 200 independent output lines to input lines forming an acting or measuring channel. VVK5 provides switching of alternating voltage up to 750V and direct voltage up to 1050V at current up to 2 A

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”
As switching elements, relays from Meder are used - SIL12-1A85-76D3K with minimum breakdown voltages contact-contact and contact-coil of the relay - 3000 V DC
When the output line is connected to the input line, a channel is formed with the following characteristics:
  • maximum switching voltage (DC / AC voltage value): 1050 V / 750 V;
  • maximum switched current: 2.0 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) no more than 1 ms
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
Functional check of the main nodes in the "Self-control" mode
Functional check with external cables using the module itself in the “OK disconnected” mode
