Basic design

The RVD110 / RVD130 are comprised of controller insert, which houses the electron-
ics, the power section, the relays and all operating elements (on the controller front),
and the base, which carries the connection terminals.
The RVD110 contains 4 relays, the RVD130 contains 7.
The operating elements are located behind a cover. At the rear of the cover, there is a
slot where the Operating Instructions can be inserted. When the cover is closed, only
the LCD and the LED for manual operation are visible. The setpoint knob is located
next to the cover.
The RVD110 / RVD130 have the standard dimensions 144 × 96 mm.
They can be mounted in 3 different ways:
•
Wall mounting
•
DIN rail mounting
•
Flash panel mounting (the front panel may have a maximum thickness of 3 mm)
The base is always mounted and wired first. To make certain the controller is always
mounted the correct way, both the base and the housing of the controller insert carry
the marking "TOP". There are 5 knockout holes for cable entries at the bottom of the
base and 5 at the top. Another 10 are in the bottom.
The controller insert is placed in the base. The insert has 2 screws each of which is
provided with a swinging lever. When the screws are tightened, their swinging levers
engage in the base. When tightening the screws further (alternately), the controller
insert pulls itself into the housing, thereby securing itself. At the same time, the electri-
cal contacts inside the base are established.
