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

Calculate Power
Requirements
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.
Determine Module
Placement in the I/O
Chassis
Set the A/B Simulation
Jumper
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.
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.

Set the Configuration
Jumpers and Key the
Backplane Connector
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.

4Key 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.
