Product Information / Datasheet (PDF)
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.
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.
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.

Motor relay MR-120
Responsible for controlling 24 V DC actuators in two monitored lines (common control) with a maximum total current of 12 A. Switching is done by pole reversal technique. Connection for two independent ventilation inputs, individually parameterizable (e.g. priority switching, gap ventilation, start-up delays). The ventilation inputs have a permanent contact in OPEN and CLOSE or automatic dead man function by prolonged pressing. The permanent control of the actuators in dead man according to the requirements for risk analysis for power operated windows is freely adjustable. MR-120 modules can be operated in solo or freely combined in ventilation and SHE groups. With fault indication. Output voltage: 24V DC, ripple < 500 mV (residual ripple < 5 %).
