Environment and Enclosure
ATTENTION: This equipment is intended for use in a Pollution Degree 2
industrial environment, in overvoltage Category II applications (as defined in IEC
60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according
to IEC/CISPR 11. Without appropriate precautions, there may be difficulties with
electromagnetic compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted within
an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or equivalent) if
nonmetallic. The interior of the enclosure must be accessible only by the use of
a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, publication
1770-IN041
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by enclosures.

Before You Begin
You can use these Series C POINT I/O™ Input Modules with DeviceNet and PROFIBUS
adapters. If you are using RSLogix 5000 software, version 11 or higher, you can also use the
modules with ControlNet and Ethernet adapters.
Use this diagram to identify the external features of the module.
The POINT I/O sink input modules are available in two-input, four-input, and
eight-input options. They install on mounting bases that mount on a DIN rail. All wiring
is made to a Removable Terminal Block (RTB) mounted on the mounting base.
Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows:
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
1. Position the mounting base vertically above the installed units (adapter, power
supply or existing module).
2. Slide the mounting base down allowing the interlocking side pieces to engage the
adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail. The mounting base snaps
into place.
Publication 1734-IN051H-EN-E - April 2013
8 POINT I/O Input Modules
Install the Module
The module can be installed before or after base installation. Make sure that the mounting
base is correctly keyed before installing the module into the mounting base. In addition,
make sure the mounting base locking screw is positione d horizontal referenced to the base.
WARNING: When 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.
Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical
resistance that can affect module operation.
ATTENTION: Do not remove or replace an Adapter Module while power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
1. Using a bladed screwdriver, rotate the keyswitch on the mounting base clockwise
until the number required for the type of module being installed aligns with the
notch in the base.
2. Make certain the DIN rail locking screw is in the horizontal position. You cannot
insert the module if the locking mechanism is unlocked.
3. Insert the module straight down into the mounting base and press to secure. The
module locks into place.
ATTENTION: Do not discard the end cap. Use this end cap to cover the
exposed interconnections on the last mounting base on the DIN rail. Failure to
do so could result in equipment damage or injury from electric shock.
Publication 1734-IN051H-EN-E - April 2013
POINT I/O Input Modules 9
Install the Removable Terminal Block
A Removable Terminal Block (RTB) is supplied with your wiring base assembly. This
allows the mounting base to be removed and replaced as necessar y without removing any
of the wiring.
To in s er t th e Re mo va b le Ter m in a l B lo c k, pr oc ee d a s f ol lo w s:
1. Insert the end opposite the handle into the base unit. This end has a curved
section that engages with the wiring base.
2. Rotate the terminal block into the wiring base until it locks itself in place.
3. If an I/O module is installed, snap the RTB handle into place on the module.
WARNING: When you connect or disconnect the Removable Terminal Block
(RTB) with field side power applied, 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.
WARNING: When used in a Class I, Division 2, hazardous location, this
equipment must be mounted in a suitable enclosure with proper wiring method
that complies with the governing electrical codes.

10 POINT I/O Input Modules
Remove a Mounting Base
To remove a mounting base, you must remove any installed module, and the module
installed in the base to the right. Remove the Removable Terminal Block, if wired.
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the Removable Terminal Block.
3. Press on the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3 and 4 for the module to the right.
6. Use a small bladed screwdriver to rotate the orange base locking screw to a
vertical position. This releases the locking mechanism.
7. Lift straight up to remove.
