Intended use
The expansion module may only be connected to a base unit from the PNOZmulti system
(please refer to the document "PNOZmulti System Expansion" for details of the base units
that can be connected).
The configurable small control systems PNOZmulti are used for the safety-related interrup-
tion of safety circuits and are designed for use in:
}
E-STOP equipment
}
Safety circuits in accordance with VDE 0113 Part 1 and EN 60204-1
The module can be used in furnaces. If the module's relay outputs shut down the entire fuel
supply and the furnace is used in continuous operation, appropriate external measures
must be used to establish diversity of the shutdown elements (requirement of EN 50156-1).
For example, an appropriate measure may be an additional, monitored switching element
(contactor or relay), which is controlled by a safe semiconductor output and is switched in
series with both relay outputs.
Alternatively the expansion module PNOZ mo5p can be used.
The coated version of the product PNOZ mo4p is suitable for use where there are in-
creased environmental requirements (see
