LED indicators

BPS 34
A BPS 34 internal green LED indicates in the reading window whether or not the supply
voltage is present.
MS 34 103 / MS 34 105
On top of the modular hood with integrated connectors a red/green status LED is located
between the M12 connectors DP IN and DP Out. It indicates the state of the Profibus
connection.

Device Construction and Components

Two models of the BPS 34 are available:
A modular hood with integrated connectors of the type MS 34 103 or MS 34 105 is always
part of a BPS 34. The purpose of both hoods is to connect the BPS 34 to the Profibus. For
this, they feature one Profibus IN and one Profibus OUT connection each, as well as an
internal switch for address setting.
If only the connection to the Profibus is intended, type MS 34 103 is sufficient.
If, in addition, switching input and output or a modular service display are to be connected,
an MS 34 105 is required. Although switching inputs and outputs are available on the
voltage supply connector, the switching inputs of the MS 34 105 have the advantage that a
standard sensor connector can be used.
