BIG-K-1A-1/12 Intrinsic Safety Barrier Analog Input
Product Description
Advantages
- Input, output and power supply 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.
- Mounting on the BIG-BAZA or MTL4500 backplane.
- Speed and ease of installation.
- Availability of power indicator.
