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 Understand Compliance to European Union Directives If this product has the CE mark it is approved for installation within the European Union and EEA regions. It has been designed and tested to meet the following directives.
PAGE 3
Analog Input Module Calculate Power Requirements 3 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 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.
PAGE 4
Analog Input Module 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.

Analog Input Module Connect Wiring to the Field Wiring Arm Connect your I/O devices to the cat. no. 1771-WG wiring arm shipped with the module. ! 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.

Analog Input Module 7 Connection Diagram for 16 Single ended Inputs and Two Wire Transmitters Note: Refer to transmitter manufacturers specifications for power supply connections. NOTE: 2 Wire Transmitter - All module commons are electrical ly tied together inside the module. - Jumper all unused channels to module common to reduce noise. + Power Supply 2 Wire Transmitter - Tie power supply grounds together to minimize ground loops. Attention: Analog input signals must be within +14.

Analog Input Module Connection Diagram for 8 Differential Inputs and Two Wire Transmitters Note: Refer to transmitter manufacturers specifications for power supply connections. NOTE: - Unused channels must have their + and inputs jumpered together and tied to module common to reduce noise. - Tie power supply grounds together to minimize ground loops.

Analog Input Module Ground the Chassis and Module Use the following diagrams to ground your I/O chassis and analog input module. Follow these steps to prepare the cable: 1 Chassis Ground When you connect grounding conductors to the I/O chassis grounding stud, place a star washer under the first lug, then place a nut with captive lock washer on top of each ground lug. Remove a length of cable jacket from the Belden 8761 cable.
