Prevent Electrostatic Discharge
ATTENTION
ATTENTION
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in
use.
To comply with the CE Low Voltage Directive (LVD), all connected I/O
must be powered from a source compliant with safety extra-low
voltage (SELV) or protected extra-low voltage (PELV).
POINT I/O is grounded through the DIN rail to chassis ground. Use zinc
plated, yellow-chromate steel DIN rail to be sure of proper grounding.
The use of other DIN rail materials, such as aluminum and 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 (7.87 in.) and use end-anchors appropriately.

ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
publication 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 Publication 11. Without appropriate

8 POINT I/O 24V dc Digital Diagnostics Input Module
Before You Begin
The module supports remove and insert under power, auto-address,
and auto-baud in compliance with the POINTBus backplane. Each
input is a sinking dc input with short-circuit and open-wire detection.
The sensor source voltage is derived from the user auxiliary power
and used as I/O power.
Understand Short-circuit Detection
The sensor source voltage (SSV) for each input is protected against
short circuits. For currents above 200 mA, a fault signal is issued and
the input LED indicator is illuminated solid red. A thermally-actuated
smart-power device or PTC is used as the protection means. On a
per-input basis, the circuit and produced data automatically reset and
SSV energizes upon removal of the short circuit. An individual fault
signal is issued for each shorted SSV condition.
The shorted input LED indicator illuminates red to denote
short-circuit fault status.
See the section on interpreting LED indicators for related information.
When the SSV is loaded to the maximum rated current of 50 mA, a
voltage drop of as much as 2.5V dc can exist between the user
auxiliary power and the SSV connection. For example, for a supply of
10V dc to a sensor with power derived from the SSV, a supply of
12.5V dc is needed at the auxiliary power connection.
Publication
1734-IN029A-EN-E - January 2007
POINT I/O 24V dc Digital Diagnostics Input Module 9
Understand Open-wire Detection
Sensor source voltage (SSV) current for each input is monitored.
Monitoring is accomplished in the SSV leg to accommodate the
largest number of sensors possible. For currents below 0.5 mA, a fault
signal is issued and the input's LED indicator blinks red. On a
per-input basis, the circuit and produced data automatically reset
upon removal of the open-wire condition. See the information about
interpreting LED indicators for related information.
By using a configuration tool, you can disable the open- wire
diagnostics on an input-point basis to keep unused input indicators
from turning red and signaling a fault when an input is not in use.
Enabling or disabling input-point level open-wire diagnostics is
implemented via the module’s EDS file, GSD file, or Logix profile and
its firmware.
You can also disable all the open-wire diagnostics, using a single
entry via the software user interface. The default configuration has
all four input channels’ open-wire indication enabled.
If a sensor with a dry contact output is used, wire one side of the
contact to the SSV terminal for the corresponding input. Wire the
other side of the contact to the input. Additionally, place a shunt
resistor in parallel with the contact, at the sensor, to cause greater
than 0.5 mA to be drawn through the SSV terminal at all times.
Install the Mounting Base
To install the mounting base on the DIN rail, proceed as follows.
1. Position the mounting base vertically above the installed units,
for example, adapter, power supply, or existing module.
2. Slide the mounting base down so that the interlocking side
pieces engage the adjacent module or adapter.

• The mounting base is correctly keyed.
• The mounting base locking screw is positioned horizontally
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.
To install the module, use this procedure.
1. Use a bladed screwdriver to 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. Be sure the DIN-rail locking screw is in the horizontal
position, noting that 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, until the module locks into place.
4. Insert the end opposite the handle into the base unit, noting
this end has a curved section that engages with the wiring
base.
5. Rotate the terminal block into the wiring base until it locks
itself in place.
6. Snap the RTB handle into place on the module, if an I/O
module is installed.

Install the Removable Terminal Block
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.
Read this for information if a removable terminal block (RTB) is
supplied with your wiring base assembly, noting that 1734-TOP and
1734-TOPS bases do not have an RTB.
To insert the RTB, proceed as follows. Note that if you pull up on the
RTB handle to remove the RTB, you can remove and replace the
mounting base as necessary without removing any of the wiring.
1. Insert the end opposite the handle into the base unit, noting
that 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 into place.
3. If an I/O module is installed, snap the RTB handle into place
on the module.
Wire the Module
See the figure and tables for information about how to wire the
module.
WARNING
If you connect or disconnect wiring while the field-side 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.
