The 1700-Sa is intended for use in Safe Areas. The two fiber-optic ports are designated ‘Ex op is’ – meaning the transmitted optical power is deemed inherently safe according to IEC 60079-28:2015.
Therefore the fiber cables can pass into Zone 2 and Zone 1 areas and connect to suitably approved and compatible link-partners such as HMIs.
The 1700-Sa functions as an un-managed Ethernet switch with both fiber and copper ports inter-connected internally. No configuration is necessary.
