BIG-2-1-12 Intrinsic Safety Barrier Discrete Input
Product Description
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.
- Signal splitter.
- 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.
