Grayed out fields apply to the Standard version only and not to the Economy modules. 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. EATON www.eaton.com...
Active modules with the additional designation “IT” are equipped with feed-in terminals and can thus supply power to the busbar. A maximum current of 20 A may be supplied per module. Modules without the additional designation “IT” are not equipped with feed-in terminals and can therefore only be supplied via the busbar. EATON www.eaton.com...

Only suitable tools may be used to actuate the cage clamp terminals (e.g. a slotted screwdriver with a blade size of 2.5 x 0.75 mm). The length of the pin (P) must not be less than 10 mm in the case of ferrules, otherwise it cannot be ensured that the ferrule will be securely clamped in the terminal. EATON www.eaton.com...
For applications where it is required that parts carrying low voltages are isolated, we offer the PXS24-BBC cover (PXS24ACC0002). Once the busbar has been shortened to the correct length, it can be connected to the designated busbar clips of the PXS24. EATON www.eaton.com 11...
Feed-in via a single power supply unit with <= 20 A If a power supply unit <=20 A is used with devices bearing the designation “IT”, power is supplied via the push-in terminals of one of the modules of the PXS24 (terminal marking 2.X and 4.X). EATON www.eaton.com...
To distribute the power supply, at least two active modules (module designation ...IT) with supply terminals are required. Power supply via the busbar feed-in terminals The maximum conductor cross-section of the cable connecting the device to the busbar supply terminals is 16 mm². The busbar is designed for currents up to 80 A. EATON www.eaton.com 13...
Two separate active power supply units can be connected to the busbar feed-in terminals. The combined rated current of the two power supplies must not exceed 80 A. The busbar is designed for currents up to 80 A. EATON www.eaton.com...
The switch at the front of the PXS24 can be used to switch the device on and off and to reset it. 7 Communication interface Both the communication port inputs and outputs conform to IEC/EN61131-2 and can therefore be connected directly to a PLC or used to control loads. The communication interface is designed as a plugable terminal. EATON www.eaton.com 15...
To enable communication with networks that are not connected to the same power supply, the communication interface is equipped with an additional ground connection. This ground connection may only be used for communication purposes! The outputs with terminal designations 5 and 6 are used to transmit the trip signal. EATON www.eaton.com...
This can be done using a variety of controllers or by means of operating elements, such as pushbuttons from Eaton's RMQ series. If the supply voltages of the controller or pushbutton are connected to a different 24 V DC potential than the PXS24, a ground connection must be established.
The applied trigger signal must be at “high” level for at least 200 ms. The path highlighted in white can be controlled by the user; the paths highlighted in gray will change in line with the changes to the white path. EATON www.eaton.com...
To be able to reset the PXS24 without an external controller and without any external voltage in the event of a fault, a pushbutton or relay contact (normally open, NO) can be connected between one of its outputs (pin 5 or 6) and one of its inputs (pin 7 or 8). EATON www.eaton.com 19...
PXS24 output (pin 5 or 6) and to the ground terminal of the communication port. 7.5.9 Overcurrent status transfer via relay Status transfer via relay can be used for potential-free switching. This also makes it possible to switch off circuits with voltages other than 24 V DC. EATON www.eaton.com...
The two permissible connection types are “sequence control” and “group error message.” A combination of the two connection types is not possible. In order to connect the individual switches, their GND terminals must be connected to each other. EATON www.eaton.com 21...
To have full control over a group of several PXS24s – as described under the option “full control via an external controller (monitoring and switching)” – their inputs and outputs can be connected to each other. In case of an error the external controller will receive a group message. EATON www.eaton.com...
In order to switch off a PXS24 by means of sequence control and a PLC, one of its inputs must be connected to one of the outputs of the master PXS. The second, free input of the PXS24 then needs to be connected directly to a controller output. EATON www.eaton.com 23...
