Grounding terminals and relays for interfaces. These interface grounding terminals with screw contacts and pluggable mini relays facilitate the setup of PLC interface relays on a standard EN busbar and ensure connectivity. The mini relays are encapsulated according to IP67 standards to protect the relay mechanism and contacts from moisture and oxidation. Narrow ground connection terminals for miniature interface relays – only 6.2 mm wide. Input voltage indication via LED. Integrated input and protection circuit. Safe electrical isolation. The 2-pole short-circuit bridges make it easy to connect to a PLC terminal of the same or a similar type without taking up space in the screw terminal. Grounding terminals and mini relays are supplied separately for replacement and system flexibility.
