This manual describes the functioning of the Standard-series PXS24 and the “stand-alone” operation. The PXS24 system
allows for many possible combinations, which are described in detail in the “PXS24 system” manual.
Up-to-date information and the most recent version of this document are available at:
Eaton.com/PXS24
We recommend downloading the latest versions of all relevant documents prior to planning.

The PXS24 series has been developed specifically for overload-protected and short-circuit proof 24 V
power supply units, of the type commonly used in automation applications.
Whenever the modules are switched on (i.e. when operating voltage is applied) they are live (provid-
ed that the slide switch at the front is set to “I”)! If the unit has tripped (following an overload or
short circuit), switching it off and back on again will reset the trip.
Please refer to the technical data of the individual components, particularly the operating voltage and
the rated current.

There are many different options for combining the various components of the PXS24 series. To avoid
restricting this flexibility, two separate series with different functionalities are available.
1.) Economy: PXS24E-…
2.) Standard: PXS24S-…

Articles marked “IT” (= “input terminal”) can be used individually (> see section on “stand-alone op-

An individual PXS24S-…/IT element can be used on its own to protect a channel. This requires the
selection of a model with input terminals (“IT”), as models without input terminals are supplied via
the busbar only.

To ensure thermal protection, modules with high amperage should not be placed directly next to one
another, wherever possible. Please also refer to the technical data of the individual components.
De-rating: If three or more 16A modules are placed directly next to each other (in the specified tem-
perature range), these must be de-rated to 13A. For this type of application, we therefore recom-
mend using 13A modules instead. If 16A modules are to be used, please leave 1HP (18 mm) between
each of the modules for cooling purposes.

“In” is used for control purposes:
Low: Module is live
High: No voltage at output
Note: The input is equipped with an internal pull-up resistor, so that the module is live without any
external connection.
Reset (remotely): Low > High
Note: An “off” signal always takes precedence (irrespective of whether it originates at the selector
switch at the front or at the “In” input), meaning the module will remain inactive until both signals
have switched to “on”!
“Out” trip signal:
Low: Module is live, no error
High: Module has tripped or was switched off manually
The GND connection at the communication port is intended for communication purposes only and
shall therefore not be loaded with currents over 200mA!
The communication port inputs and outputs conform to IEC/EN61131-2. It is therefore possible to
connect the module directly to a PLC, or to use it to control loads.
Note: The communication link is implemented via a dedicated port that is not available in the “Econ-
omy” series.

If individual error messages are not required, the trip outputs (“Out”) of several PXS24 modules can
be connected. A total of at most 30 modules can be connected in this way.
Note: This feature cannot be used simultaneously with the subsequent control.
