The thermocouple/mV 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 bag

Thermocouple/Millivolt Input Module Understand Compliance to European Union Directives 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
Thermocouple/Millivolt Input Module Calculate Power Requirements 3 The module receives its power through the 1771 I/O power supply and requires 850mA 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 ATTENTION: Do not insert or remove modules from the I/O chassis while system power is ON.
PAGE 4
Thermocouple/Millivolt Input 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. • Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.
PAGE 5
Thermocouple/Millivolt Input Module 5 Connect your I/O devices to the cat. no. 1771-WI 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.
PAGE 6
Thermocouple/Millivolt Input Module Recommended maximum cable length for voltage-mode input devices is 50 feet, due to possible signal degradation and electrical noise immunity in typical industrial environments. When using shielded cable or shielded thermocouple extension wire, ground the foil shield and drain wire only at one end of the cable.

Thermocouple/Millivolt Input Module Configure the Module You must configure the module to conform to the analog device and specific application that you have chosen. Use the configuration information below to configure your module to your specifications. For detailed configuration information, see Module Configuration" in your (publication 1771Ć6.5.130). Word Dec.

Thermocouple/Millivolt Input Module Design your program to monitor status bits in the lower byte of word 1, and to take appropriate action depending on your application requirements. You may also want to monitor these bits while troubleshooting with your industrial terminal. The module sets a bit (1) to indicate it has detected one or more of the following conditions: /%4,& *2 0/6&1&% #43 )"2 ./3 1&$&*5&% *32 '*123 $/.'*(41"3*/. #,/$+ 31".2'&1 !)& (1&&.

Thermocouple/Millivolt Input Module 11 Design your program to monitor status bits in word 13 during auto–calibration, and to take appropriate action depending on your requirements. You may also want to monitor these bits while troubleshooting with your industrial terminal. The module sets a bit (1) to indicate it has detected one or more of the following conditions as shown below. 13 6 The EEPROM could not be written.

Thermocouple/Millivolt Input Module Backplane Power 850mA @ 5V; Power Dissipation 4.25 Watts maximum Thermal Dissipation 14.5 BTU/hr Environmental Conditions Operating Temperature: Rate of Change: 0 to 60oC (32 to 140oF) Ambient changes greater than 0.
PAGE 13
Thermocouple/Millivolt Input Module 13 Modules are typically calibrated at 25oC. • If the I/O chassis in which the 1771-IXE is operating is at 25oC, column A represents the maximum error for that thermocouple type. • If the chassis operating temperature is less than or greater than 25oC, use the formula below to calculate the maximum error.
PAGE 14
Thermocouple/Millivolt Input Module Source resistance causes similar errors to occur with millivolt inputs. If source resistance is less than 100 ohms, no compensation is necessary to maintain stated accuracy.

Thermocouple/Millivolt Input Module The following is a list of major differences between Series A, Series B, Series C and Series D Thermocouple/Millivolt Input module (cat. no. 1771–IXE). Calibration Uses potentiometers for calibration settings with calibration done at -99 and +99mV. Calibration is done automatically using auto-calibration feature, or manually through programming.
