2 Product Description
2.1 General description
The versions of the vacuum switch and pressure switch in the VSi series are referred to only
as the switch below.
The VSi-series switch can be operated in two operating modes. Users can choose between direct
connection to discrete inputs (standard I/O = SIO mode) or connection through the communication line
(IO link Class A).
Switching points are indicated using one or two orange LEDs. If the switching point is not active, the
operational readiness is indicated by a green LED.
Additionally, a multitude of information and status reports for the switch can be accessed using
wireless communication with NFC (Near Field Communication).
The parameters can also be set using two buttons on the display version (VSi-…-D). The current
system status and the settings are shown on a display.
The fluid connection offers the opportunity to align the switch in a screwed-in position.
2.2 Versions
Each switch has a precise item designation (e.g. VSi P 10 D M8-4) that is composed of the following
type keys:
Type
Pressure range
Display
Electrical connection
VSi
V (-1 to 0 bar)
D (with integrated display)
M12-4 (1xM12, 4-pin)
VP8 (-1 to +8 bar)
M8-4 (1xM8, 4-pin)
P10 (0 to +10 bar)
