Motor relays with built-in overload switch
R0901 and R0902 are master relays for 1 or 2 gear motors intended for shading or for ventilation systems. The relays can be used for manual operation of the gear motor and as power relays for control from, for example, climate computers. R0901 and R0902 have built-in overload switches as well as an intermediate relay which makes the control current very low (approximately 10 mA).
The relays can be extended with our MR102 fire relays.
They are control units which will force the screens or windows to open or close when activated by an external signal from smoke or fre alarm. Both relays are supplied in DGT by Senmatic’s well known splash-proof plastic box. RO901 and RO902 can be delivered for various voltages with overload switches up to 10 Amps. The 115 V relay is UL and C-UL approved.
MR906 is a control unit especially made for single phase 230 V reversing tube motors, as used for roller screens. On each unit, a built-in time delay of approximately two seconds protects the tube motor. The fre relay is integrated in MR906. MR906 can be built into control cabinets or delivered with six units in the normal relay box with power supply built-in.
