Prevent Electrostatic Discharge
The analog input module is sensitive to electrostatic discharge.
ATTENTION: Electrostatic discharge can damage
integrated circuits or semiconductors if you touch
!
backplane connector pins. Follow these guidelines
when you handle the module:
• Touch a grounded object to discharge static potential
• Wear an approved wrist-strap grounding device
• Do not touch the backplane connector or
connector pins
• Do not touch circuit components inside the module
• If available, use a static-safe work station
• When not in use, keep the module in its
static-shield box

Analog Input Module 3
Calculate Power Requirements
Determine Module Placement in the I/O Chassis
The module receives its power through the 1771 I/O power supply
and requires 500mA from the backplane.
Add this current to the requirements of all other modules in the I/O
chassis to prevent overloading the chassis backplane and/or
backplane power supply.
Place your module in any I/O module slot of the I/O chassis except
for the extreme left slot. This slot is reserved for PC processors or
adapter modules.
ATTENTION: Do not insert or remove modules from
the I/O chassis while system power is ON. Failure to
!
observe this rule could result in damage to module
circuitry.
Group your modules to minimize adverse affects from radiated
electrical noise and heat. We recommend the following.
• Group analog input and low voltage dc modules away from ac
modules or high voltage dc modules to minimize electrical noise
interference.
• Do not place this module in the same I/O group with a discrete
high-density I/O module when using 2-slot addressing. This
module uses a byte in both the input and output image tables for
block transfer.
Set the A/B Simulation Jumper
The module is shipped with the A/B simulation jumper set in
position POS G for Series C applications. This setting returns input
data above and below the range end points. If you are replacing a
Series A or B 1771-IFE module with this module, reset the
simulation jumper to the POS E position as shown below.
Set the Series A/B Simulation Jumper
1. Locate the simulation jumper at the top edge
of the module circuit board.
2. Using your fingers, slide the jumper off the 2 posts.
3. Carefully position the jumper on 2 of the 3 posts that
correspond to your requirement.

The module has configuration jumpers for determining the input type
(voltage or current) desired for each input. The module is shipped
with the configuration jumpers positioned for voltage mode and
the A/B simulation jumper set for Series C. If you are replacing a
Series A or B 1771-IFE module with this module, reset the
simulation jumper as shown above.
You can select either voltage or current for each input, but all inputs
must be either single-ended or differential. Do not mix single-ended
and differential inputs on the module.
Reposition the configuration jumpers associated with each input

channel according to your requirements
You can mix voltage mode and current mode settings on
the module. Make sure that the entire module is set for
either singleended or differential. Do not mix them.

Key the Backplane Connector
Place your module in any slot in the chassis
except the leftmost slot which is reserved for
processors or adapters.
Position the keying bands in the backplane connectors
to correspond to the key slots on the module.
Place the keying bands:
between 10 and 12
between 24 and 26
You can change the position of these bands if
subsequent system design and rewiring makes
insertion of a different type of module necessary.

Install the Module and Field Wiring Arm
!
ATTENTION: Remove power from the 1771 I/O
chassis backplane and field wiring arm before
removing or installing an I/O module.
• Failure to remove power from the backplane or
wiring arm could cause module damage, degradation
of performance, or injury.
• Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
Place the module in the card guides on the top and bottom of the chassis that guide the module into position.

Important: Apply firm even pressure on the module to seat it into its
backplane connector.

Snap the chassis latch over the
top of the module to secure it.
Swing the chassis locking bar
down into place to secure the
modules. Make sure the locking
pins engage.

Attach the wiring arm (1771WG) to the horizontal
bar at the bottom of the I/O chassis.
The wiring arm pivots upward and connects with
the module so you can install or remove the
module without disconnecting the wires.
