The Westermo SA units are available in MD-63 (point to point) and LD-63 (multidrop) versions. These units are specially designed to connect via fibre optic equipment that is using ABB Sattbus interface.
The fibre optic cable is completely immune to external interference, which makes it ideal for harsh industrial environments. Another reason may be the need for a high level of security as fibre optic cable is very hard to tap. The SA units are available in both multi- and single mode versions.
