The MR-120 is a base module for the M-SHEV module center that connects to the other modules in BUS. It is the output module that supplies the connected actuators.
Optional expandable module for flexible applications
Together with the other components signaling interface (optional), central interface, sensor interface and the power supply, the motor relay is housed in a sturdy but flat sheet steel housing of the M-SHEV. Here it can be extended as required by the connection to a sensor interface.
Output module for powering the connected actuators
The motor relay serves as an output module for all connected actuators. It is directly coupled to a sensor interface. Each SHE group requires a sensor interface. However, any number of motor relays can be connected to this, so that a greater variety of applications is possible.
Your benefits at a glance:
- Any number of motor relays can be connected
- insensitive module against voltage and current peaks
Under the Construction Products Regulations (CPR) it is a legal requirement to use only certified products for smoke ventilation. It is the responsibility of the installer to ensure installations meet the relevant standards. For more information see SCS Group’s Technical Bulletin.
