Assignment Remark
Connector 1 Power connector
1.1 24 V DC
(U
S
)
24 V segment
voltage supply
The supplied voltage is directly routed to the potential jumper.
1.2 24 V DC
(U
ILC
)
24 V supply The 7.5 V communications power (U
L
) for the ILC and the connected local
bus devices is generated from this voltage. The 24 V analog voltage (U
ANA
)
for the local bus devices is also generated.
2.1, 2.2 24 V DC
(U
M
)
24 V main
voltage supply
The main voltage is routed to the local bus devices via the potential jumpers.
1.3 LGND Reference
potential logic
ground
The potential is reference ground for the communications power.
2.3 SGND Reference
potential
segment
ground
The reference potential is directly led to the potential jumper and is, at the
same time, reference ground for the main and segment supply.
1.4, 2.4 FE Functional
earth ground
(FE)
Functional earth ground must be connected through the power supply. The
contacts are directly connected to the potential jumper and FE springs on
the bottom of the housing. The Inline Controller is grounded when it is
snapped onto a grounded DIN rail. Functional earth ground is only used to
discharge interference.
NOTE:
Protect the supply voltage externally according to the connected
load (local bus devices) with 8 A, maximum. Make sure the
external fuse blows in any case.
NOTE:
Protect the supply voltage externally according to the connected
load (local bus devices) with 2 A, maximum. Make sure the
external fuse blows in any case.
NOTE:
Protect the supply voltage externally according to the connected
load (local bus devices) with 8 A, maximum. Make sure the
external fuse blows in any case.
NOTE:
– The maximum total current flowing through the potential jumpers is 8 A.
– When terminal points 1.1 and 2.1 (or 2.2) are jumpered, the maximum
permissible current of 2.5 A (see "24 V segment supply" on page 2-32) flowing
through the potential jumpers U
M
and U
S
(total current) must not be exceeded.
