Description
The F3330 984333002 I/O subrack fullfills the safety requirements of the requirement class 6.
Slots 1 to 16 are provided for any type of input/output modules of the HIMA automation system. Slot 17 is provided for the coupling module F 7553 for the I/O bus.
Slots 18 to 21 hold the power distribution modules F 7133 They are noninteractive and have a fuse monitoring for fuse fail by means of a LED and a contact.. The power distribution module F 7133 can be used to fuse the I/O modules as well as the sensors and the actors.
There is a cable tray under the input/output subrack. It is equipped with a receptable for the label which can be hinged to provide easy access to the cables.
24 V DC Power Supply and Distribution
Standard solution: The 24 V DC power is distributed via a plug-in fusing and power distribution unit (refer to the HIMA articles). For the input/output racks max. 25 A back-up fuses are provided for L+. The power for the input/output modules is fed in at the backside of the power distribution modules F 7133 via XG.7/8/9/10.
Each I/O module is related to a fuse on the module F 7133 (refer also to the description of the assembly kit B 9302).

Extension of the 5 V DC Power Supply
If the power requirements of the 5 V circuits is > 18 A an additional power supply has to be used. For this purpose the B 9361 assembly kit can be used which provides the possibility of applying three 24 V/5 V power supplies F 7126 together with the monitoring module F 7131 in an additional subrack.
The 5 V output circuits of the additional power supply must not be switched in parallel with the ones from the central rack. Apart from them they supply their own circuits. The reference poles GND have to be connected together.
The power supply units of the additional power supply (assembly kit B 9361) emit monitoring signals. These signals can be taken from the XG1 terminal block on the rear side of the subrack (see B 9361 assembly kit). They can be fed into the PLC via digital input modules. In the logic of the PLC the signals are used to trigger an error message.
