Product Overview

1756-IR6I is an Allen-Bradley ControlLogix 1756 temperature-sensing analog input module with six individually isolated RTD channels.

Rockwell Automation specifies four selectable resistance ranges from 1-487 Ohm through 8-4000 Ohm and 16-bit conversion for supported platinum, nickel and copper RTD sensors.

The module accepts 2-wire, 3-wire and 4-wire field connections through a 20-pin removable terminal block and occupies one ControlLogix chassis slot.

Features

Channel-to-channel isolation

All six RTD inputs are individually isolated from one another and from the ControlLogix backplane.

Multiple RTD families

The module supports published platinum, nickel and copper RTD sensor curves.

Four resistance ranges

Select the resistance span and matching 16-bit resolution required by the sensor application.

Wire compensation

Official connection diagrams support 2-wire, 3-wire and 4-wire RTD or resistance measurements.

Wiring

Field wiring	Use a 1756-TBNH or 1756-TBSH 20-pin removable terminal block housing; order the RTB separately.
Two-wire connection	Short IN-x/B and RTN-x/C together as shown in the official resistor and calibration wiring guidance.
Three-wire connection	Connect IN-x/A, IN-x/B and RTN-x/C and terminate the shield according to the official diagram.
Four-wire connection	Use the published four-wire arrangement and shield grounding while maintaining the 250 V isolation limits.

Installation

01 - Verify the complete catalog number

Match 1756-IR6I on the quotation, module label, packaging and Rockwell Automation discontinued-product record.

02 - Confirm the sensor type

Verify the RTD material, coefficient, nominal resistance and required temperature range before selecting the input configuration.

03 - Select the RTB

Choose 1756-TBNH or 1756-TBSH for the 20-pin connection and key the RTB mechanically.

04 - Wire each isolated channel

Follow the exact 2-wire, 3-wire or 4-wire diagram and preserve shield and channel isolation practices.

05 - Configure the range

Set the matching resistance range, data format, notch filter and scaling, then perform the specified calibration checks.

Environment

FAQ

Q1. How can the exact quoted 1756-IR6I be verified?

Match 1756-IR6I on the quotation, module label and packaging. Confirm six individually isolated RTD channels, the four published resistance ranges and the 20-pin 1756-TBNH or 1756-TBSH interface.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the full label, serial and series markings, CAL and OK indicators, 20-pin RTB connector, backplane connector and housing. Check for terminal wear, changed labels, repaired plastic or residue from prior cabinet installation.

Q3. How should supplier legality and reliability be checked?

Verify the supplier legal entity, registered address, invoice details, payment beneficiary and traceable sales contact. The offer must state Allen-Bradley, 1756-IR6I, discontinued status, condition, quantity and included CJC or RTB accessories if any.

Q4. Which specifications must engineering confirm before purchase?

Confirm the RTD curve and nominal resistance, 1-487 through 8-4000 Ohm range, 2-wire, 3-wire or 4-wire method, 250 V isolation, 1756-TBNH or 1756-TBSH RTB, backplane power, firmware profile and chassis compatibility.

Q5. What physical evidence should be requested before payment?

Ask for date-marked photos showing the full 1756-IR6I label, serial and series markings, six-channel analog input faceplate, RTB connector, backplane edge connector, housing condition and packaging.

Q6. Can 1756-IRT8I or 1756-IR12 replace 1756-IR6I?

Not automatically. They differ in channel count, isolation, supported sensor modes, RTB, resolution and software profile. Complete an engineering and program migration review before any replacement.
