Device description
The safety relays of the MSI-TRxB series are safety monitoring devices for electro-sensitive protective
equipment (ESPE), type 2, on machines with risks of bodily injury (acc. to EN 61496-1:2013). 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.
