The safety relays of the MSI-TB series are safety monitoring devices for electro-sensitive protective equip
-
ment (ESPE), type 2, on machines with risks of bodily injury (acc. to EN 61496-1). As part of the electrical
equipment, they enable machines or systems to achieve a safe state before persons can be endangered.
The safety relay is intended for installation on the DIN rail in the cabinet and is wired via the 16 terminals .
All connection terminals are pluggable. The individual terminal blocks are mechanically coded to prevent
swapping or skewed plug in. The safety relays are available with screw terminals or spring-cage terminals.
The complete safety system consists of a safety relay and safety sensors connected to it.
