I.    Structure features

    WZD-1100 DC is a kind of small-scale instrument of panel installation type. The panel dimension is
 40×80mm. Hole dimension is 36×76mm.

II. Application scope

   WZD-1100 DC series remote operation station is a kind of remote control equipment. This instrument
series can be configured with one dictator and three strong-current indicator keys at most , which can
realize remote control towards electric operator (electric-driven door) or other electric equipment in
the system with a push on the surface key.

VII.  Operation and maintenance

   This instrument uses imported strong-current key switch and can control directly various electric-driven
door and other electric equipment.

   When the power for electric operator is quite high, the operation station with internal relay output can
be used. For example WZD-11E0DC and its wiring is shown as Figure 7-1.
