BIG-1-1-11 Intrinsic Safety Barrier Analog Input
Product Description
Advantages
- HART signals are transmitted in both directions.
- 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 rated SIL3.
- Mounting on a standard 35mm wide DIN rail.
- Easy installation/dismantling of the product.
- The compact body allows for tighter installation.
- Availability of power indicator.

| Inter-verification interval: | 2 years (for BIG-1-1-11)* 4 years (for BIG-1-1-11/P)* *By default, barriers are supplied without initial verification. Please indicate the need for verification when submitting your request. The verification cost will be specified when issuing the technical quotation. Verification increases the delivery time by approximately two weeks. |
