BIG-2-1-22 Intrinsic Safety Barrier Discrete Input

Product Description

The barrier is designed for intrinsically safe transmission of discrete signals (dry contact or NAMUR sensor) from a hazardous area to a safe area using galvanic isolation.

Advantages

  • Input, output and fault indication signals are galvanically isolated from each other.
  • The electronic circuits of the barriers are coated with varnish, which additionally protects the elements from external factors.
  • High conversion accuracy ±0.1%
  • These products are designed with functional safety in mind and are SIL2/SIL3 compliant.
  • Mounting on a standard 35mm wide DIN rail.
  • Easy installation/dismantling of the product.
  • The compact body allows for tighter installation.
  • Availability of LED indication.
  • Configurable via DIP switch.

LED indication algorithm

If the input current is less than 0.08 mA, an open circuit condition is detected on the input line, the device enters a safe functional state, and the output relay is de-energized. If the input current is greater than 6 mA, an input line short circuit condition is detected, the device enters a safe functional state, the output relay is de-energized, and the indicator flashes red.
