Placement of PM-O DC 2x24V Outgoing Module
Outgoing module
With the ET 200pro distributed I/O system, you ideally place the outgoing module directly to
the right of the F-switch during ET 200pro installation.
You can install additional power and electronic modules on the right of the outgoing module.
You can find information on other possible installations of the outgoing module in the FAQs
for ET 200pro (
http://support.automation.siemens.com/WW/view/en/26694409
The 1L+ electronic/encoder supply of the outgoing module is protected by means of an
electronic circuit and is short-circuit proof. The 2L+ load voltage supply is protected by
means of the PM-E power module or the interface module of the ET 200pro distributed I/O
system.
Tapping of the electronic/encoder supply and load voltage supply
In this example, the PM-O DC 2x24V outgoing module is placed after an F-switch. The
F-switch provides for safe shutdown of the loads connected to the outgoing module.
Additional information regarding the F-switch
