Device description

The MSI-TRMB safety relays can be used as follows:

• Safety monitoring devices for electro-sensitive protective equipment (ESPE) on machines which 

pose a risk of injury (according to IEC 61496-1),

• Safety sequential device for 2-channel E-Stop monitoring, safety sequential device for 2-channel 

safety door monitoring.

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 DIN rail mounting and is wired via 16 terminals. It must be installed in a 

housing or switch cabinet (IP54 or higher).
The complete safety system consists of a safety relay and safety sensors connected to it.
