Product and functional description
The TR4-...-230 cut-off relay is a control relay for controlling blind and shutter motors with mechanical or electronic limit switches. The cut-off relay is used to
to prevent unauthorized parallel switching of blind or shutter motors. Up to four motors can be connected to each TR4-...-230.
If several motors are to be operated, several cut-off relays can be connected according to the circuit diagram.
Central control
all connected motors can be operated simultaneously via the central control unit. Blind switches and blind push-buttons, shutter timers are suitable as switching devices,
EIB shutter actuators and various controls with potential-free contacts. Important: Switchover time between up and down command >= 0.5sec. must be observed, otherwise the motor or relay may be damaged
Damage to the motor or relay is possible (observe the technical data of the motors).
Adding several cut-off relays
Several cut-off relays can be connected together according to the circuit diagram. only the current for the relay coils flows via the Up or Down control inputs, not the motor current
the motor current. The load on the central control unit is therefore minimal.
