Compatibility
Install Your Digital Input Module
The module mounts on a 1794 terminal base.
1. Rotate the keyswitch (1) on the terminal base (2) clockwise to position 2 as
required for this type of module.
2. Make certain the flexbus connector (3) is pushed all the way to the left to
connect with the neighboring terminal base/adapter. You cannot
install the module unless the connector is fully extended.
3. Make sure the pins on the bottom of the module are straight so they will
align properly with the connector in the terminal base.
4. Position the module (4) with its alignment bar (5) aligned with the groove
(6) on the terminal base.
5. Press firmly and evenly to seat the module in the terminal base unit. The
module is seated when the latching mechanism (7) is locked into the
module.
Connect Wiring for the 1794-IB8, -IB16, and -IB16K using a 1794-TB3
or -TB3S
1. Connect individual input wiring to numbered terminals on the 0…15 row
(A) as indicated in the following table on the next page.
2. Connect the associated +V DC power lead of the input device to the
corresponding terminal on the 34…51 row (C) for each input as indicated
in the following table. (The +V power terminals of row (C) are internally
connected together.)
3. Connect the associated input common (3-wire devices only) to the
corresponding terminal on the 16…33 row (B) for each input as indicated
in the following table. (Commons are internally connected together.)
4. Connect +V DC power to terminal 34 on the 34…51 row (C).
5. Connect DC common to terminal 16 on the 16…33 row (B).
6. If daisychaining power to the next terminal base, connect a jumper from
terminal 51 (+V DC) on this base unit to terminal 34 on the next base unit.
7. If continuing DC common to the next base unit, connect a jumper from
terminal 33 (common) on this base unit to terminal 16 on the next base
unit.
The following information applies when
operating this equipment in hazardous
locations: Informations sur l’utilisation de cet
équipement en environnements
dangereux:
Products marked “CL I, DIV 2, GP A, B, C, D”
are suitable for use in Class I Division 2
Groups A, B, C, D, Hazardous Locations and
nonhazardous locations only. Each product is
supplied with markings on the rating
nameplate indicating the hazardous location
temperature code. When combining products
within a system, the most adverse
temperature code (lowest “T” number) may
be used to help determine the overall
temperature code of the system.
Combinations of equipment in your system
are subject to investigation by the local
Authority Having Jurisdiction at the time of
installation. Les produits marqués "CL I, DIV 2, GP A, B, C,
D" ne conviennent qu’à une utilisation en
environnements de Classe I Division 2
Groupes A, B, C, D dangereux et non
dangereux. Chaque produit est livré avec des
marquages sur sa plaque d’identification qui
indiquent le code de température pour les
environnements dangereux. Lorsque
plusieurs produits sont combinés dans un
système, le code de température le plus
défavorable (code de température le plus
faible) peut être utilisé pour déterminer le
code de température global du système. Les
combinaisons d’équipements dans le
système sont sujettes à inspection par les
autorités locales qualifiées au moment de
l’installation.
WARNING
EXPLOSION HAZARD
• Do not disconnect equipment unless
power has been removed or the area
is known to be nonhazardous.
• Do not disconnect connections to this
equipment unless power has been
removed or the area is known to be
nonhazardous. Secure any external
connections that mate to this
equipment by using screws, sliding
latches, threaded connectors, or
other means provided with this
product.
• Substitution of components may
impair suitability for Class I, Division
2.
• If this product contains batteries,
they must only be changed in an area
known to be nonhazardous.
AVERTISSEMENT
RISQUE D’EXPLOSION
• Couper le courant ou s’assurer que
l’environnement est classé non
dangereux avant de débrancher
l'équipement.
• Couper le courant ou s'assurer que
l’environnement est classé non
dangereux avant de débrancher les
connecteurs. Fixer tous les
connecteurs externes reliés à cet
équipement à l'aide de vis, loquets
coulissants, connecteurs filetés ou
autres moyens fournis avec ce
produit.
• La substitution de composants peut
rendre cet équipement inadapté à
une utilisation en environnement de
Classe I, Division 2.
• S’assurer que l’environnement est
classé non dangereux avant de
changer les piles.
ATTENTION
To comply with the CE Low Voltage Directive (LVD), this equipment must
be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
The following communication adapters are required to ensure compatibility with
the 1794-IB32:
Remote I/O 1794-ASB series E or later
1794-ASB2 series D or later
ControlNet 1794-ACN15 series C, firmware revision 4.1 or later
1794-ACNR15 series C, firmware revision 4.1 or later
DeviceNet 1794-ADN Series B, firmware revision 2.4 or greater for out-of-box
compatibility
Ethernet 1794-AENT series A, firmware revision 2.4 or later
PROFIBUS 1794-APB series A, version 1.1 of the GSD file
(You can download the GSD file at www.ab.com/networks/gsd.)
ControlLogix Family RSLogix5000 programming software, version 11 or later
ATTENTION
During mounting of all devices, be sure that all debris (such as metal chips
and wire strands) is kept from falling into the module. Debris that falls into
the module could cause damage on power up.
WARNING
If you insert or remove the module while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
