HI 803 211 E Rev. 1.01.00
The L- is connected to the I/O modules through the front panel of the power distribution module
via the cable plugs.
In Figure 27, the power supply of the transmitter circuits is tapped at the front of the F 7133
power distribution module. The transmitters are protected by the same fuse as the input module
.
4.3.7.1
5 V Distribution for HIQuad X
To generate 5 V power supply, a base rack can be equipped with up to 5 (H41X: 2) F-PWR 01
power supply units that are connected in parallel. The 5 V power supply is distributed to each
slot via the backplane PCB. The 5 V power supply is monitored by the power supply units and
its status is transmitted to the processor modules. In the user program, system variables can be
used to evaluate the status of the power supply units.
4.3.7.2
5 VDC Distribution for H51X
26 connection points can be used to distribute the 5 V power supply through terminal blocks
XG2 and XG3 for 5 V, or XG4 and XG5 for GND. The supply voltage is distributed in a star
configuration, see Figure 25. The resistance of a 5 V supply line with a maximum length
between H51X base rack and extension rack of 12
m must be ≤ 40 mΩ. If cables longer than
3 m are used, HIMA recommends shielding the cables to protect them against transient
interference (LIY-CY), and applying the shield at both sides as flat as possible.
To connect cables with a cross-section larger than 2.5 mm², pin terminals with a pin diameter
< 2 mm or other suitable transfer terminals can be used.
The I/O processing modules (F-IOP 01) monitor the 5 V power supply of the racks on which
they are installed. If the minimum voltage is underrun, I/O processing modules switch off the I/O
level of their rack.
HIMA uses yellow wires for 5 V and green wires for GND. If the H51X system is distributed
among several control cabinets, separate power supply units may be necessary to supply 5 V to
the control cabinets without base rack, see Chapter 4.3.8 for details.
The wires on the extension racks are connected to the flat connectors XG.4 (5 V) and XG.12
(GND), and the shield to the PE connector. The voltage is distributed to the I/O modules via the
backplane PCB.
