Types of Blind Motors Supported by CRS-HH-REL-10

The CRS-HH-REL-10 relay module supports blind motors with an operating voltage of 120 or 240 VAC, 50/60 Hz.

Para mais informações, consulte Selection of Light and Blind Equipment .

Other types of blind motors are supported by means of external relays.

This section provides application examples that show how the following types of blind motors can be connected to and controlled by the CRS-HH-REL-10 relay module using external relays:

  • 24 VDC motors controlled by reversing the polarity of the voltage

  • 24 VDC and 120/240 VAC motors designed for dry contact control

Nota

Consult the blind motor documentation to select the appropriate type of blind control. Low-voltage (24 VDC) motors controlled by reversing the polarity of the voltage, and high-voltage (120/240 VAC) up/down controlled blinds, are typically controlled using the blind objects in the EcoStruxure Building Operation software. Dry contact controlled blinds are typically controlled using the relay objects and require additional programming. Para mais informações, consulte Relay 10 Module Overview .

24 VDC motors controlled by reversing the polarity of the voltage

The following wiring diagram shows an example how a DPDT (Double Pole Double Throw) relay can be used to connect a 24 VDC motor for which the forward/reverse (clockwise/counterclockwise) control is done by changing the polarity of the DC voltage. The DPDT relay used in this example is Schneider Electric part number RSB2A080BDPV.

24 VDC and 120/240 VAC motors designed for dry contact control

The following wiring diagram shows an example how two SSRs (Solid State Relays), one SSR for up and one SSR for down, can be used to connect a 24 VDC motor that is designed for dry contact control (typically with a control voltage of 5 VDC). 120/240 VAC motors designed for dry contact control can be connected in a similar way. The SSR used in this example is Schneider Electric part number SSM1D26BD. The contact rating for the internal relays (DO1 and DO2) specifies a minimum applicable load of 0.5 W (minimum applied voltage is 12 VDC). An external resistor (R) may be needed to meet the contact rating requirement.
