Description
In the subrack, F8628X slots 4 to 15 are provided for the input/output modules. Any arrangement of I/O module types is possible. In PES with redundant I/O bus, the modules on slots 4 to 9 are assigned to the 1st I/O bus and 10 to 15 to the 2nd I/O bus.
Slots 1 to 3 hold the power distribution modules F 7133. The power distribution module F 7133 can be used to fuse the modules as well as the sensors and the actors. They are non-interactive and have a fuse monitoring for fuse fail by means of a LED and a contact.
There is a cable tray under the subrack. It is equipped with a receptable for the lable which can be hinged to provide easy access to the cables.

F8628X Standard solution: The 24 V power L+ is distributed via a plug-in fusing and power distribution unit (refer to the HIMA articles). A 16 A back-up fuse is provided. The power for the input/output modules is fed in at the backside to the slots of the power distribution modules via XG.6/7/8. Each I/O module is related to a fuse on the module F 7133 (refer also to the description of the assembly kit B 4…). The supply of the I/O modules is either via the cable plug on the front side or via the connection already integrated in the I/O busboard (for (Ex)i modules and partly analog input modules).
The relation between the power distribution modules with 4 fuses and the slots of the I/O modules is as follows:
F 7133 in slot 1 supplies I/O slots 4 … 7
F 7133 in slot 2 supplies I/O slots 8 … 11
F 7133 in slot 3 supplies I/O slots 12 … 15
L- is also taken from the plug-in power distribution unit to be connected to the potential distributor XG. 14. So all power distribution modules F 7133 are internal connected with L-. Via the front side of the power distribution modules the L- is also fed to the input/output modules via the cable plugs.
The circuit feeding the sensors is connected via the front to the F 7133 module. It is advisable to supply the input module and the appertaining sensors via the same circuit of the power distribution module F 7133.
