Digital Input Module NAMUR Ex i Inputs, 16 Channels Series 9470/22
Components
Overview
1 Protective cover with symbol label (opened)
2 Information on the module (serial number, hardware
revision number, software revision number, manufac-
turing date, e.g.: 123456DE9999 Rev.A 01-01 0508)
3 Detent lever for removing the module from the BusRail
4 LED for status or fault indication (further information
see "LED Indications and Troubleshooting")
5 Plug-in terminal X2
6 Plug-in terminal X1
Plug-in terminals X1 and X2
The modules have two plug-in terminals X1 and X2 for
connection of the field devices.
The plug-in terminals have 16 terminals each for connection of
the field cables.

Designing
The national installation instructions
(e.g. IEC/EN 60079-14) must be observed.
Intrinsically-safe and non-intrinsically safe circuits must
not be used in a common cable duct!
Ensure that there is a distance of at least 50 mm
between connection facilities of intrinsically-safe and
non-intrinsically safe circuits!
In the protective cover there is a symbol label, which
can be used for entering the assignment of the field
devices to the channels.
Labelling of the symbol label can be performed,
for example by means of the IS Wizard.
✗
The module is intended for IS 1 field stations and can be
installed in hazardous areas of Zone 1/Division 1, Zone 2/
Division 2, Zone 21 or Zone 22.
✗
The module is installed for designated use on the
IS1 BusRail.
✗ A mixed arrangement of the BusRail with different
I/O modules is allowed. When assembling a Zone 1 module
05687E00
near Zone 2 module (94../15) it is required to assemble a
partition (ID-No.: 162740)!
✗
Operation of the module is only admissible in three
assembling positions:
assembling direction above:
✗
Connect only intrinsically-safe circuits to the connection
terminals of the module. The safety-related values of
connected sensors must be compatible to safety-related
values of the inputs. According to IEC/EN 60079-14 following
applies: U ) U , l ) I
i o i
✗
The intrinsically-safe input current circuits may also be used
in areas of zones 20, 21 and 22 with dust explosion hazard.
In this case ensure that connected electric equipment is
correspondingly certified according to specifications of the
category 1D or 2D.
