Intrinsically safe barriers of БИЗ type

Category: Intrinsically safe automation system components

Intrinsically safe barriers type БИЗ are designed for explosion protection of control and indication devices, RS type sensors and interfaces installed in Explosive areas. Installation of barriers is allowed only outside the explosive area, or in an explosion-proof enclosure.
Designer and Manufacturer: PJSC “DEG”.

MAIN FUNCTIONS

Barriers provide intrisic safety of:

  • analog signals, that enter in the hazardous area from circuits of automation devices (controllers,  analog controllers, etc.), which are located in a safe area;
  • analog signals, that come from sensors from the explosive area to the inputs of automation devices, which are located in a safe area;
  • discrete signals formed by switching repeater of sensors and relays located in the hazardous area;
  • discrete signals formed by switching repeater of switching devices located in a safe area;
  • discrete signals formed by switching repeater of sensors and relays which are located in a safe area;
  • discrete signals formed by switching repeater of switching devices which are located in a safe area.
