1769-IR6 RTD / Resistance Input Module

The Allen-Bradley 1769-IR6 is a CompactLogix analog RTD/resistance input module that has Six (6) RTD

input channels available. The input ranges of this module are 0 to150 Ohms, 0 to 500 Ohms, 0 to 1000

Ohms, and 0 to 3000 Ohms and it has a maximum common mode voltage range of +/- 10 Volts DC. The

1769-IR6 module has 1.5 Watts of power dissipation and it draws currents of 100 mA at 5.1 Volts and of

45 mA at 24 Volts. It also has an isolation voltage of 720 Volts DC for 1 minute from channel to bus, optical

and magnetic (qualification), as well as a working voltage of 30 Volts AC/30 Volts DC. Its open circuit

detection time ranges from 6 milliseconds to 303 seconds and it has impedances of 25 Ohms for the cable and of more than 10 megaohms for the input.
The Allen-Bradley 1769-IR6 module has a built-in status LED available and it can be mounted using a

DIN rail or panel. When using a panel, the 1769-IR6 module has an operating shock of 30 G, a relay

operating shock of 7.5 G, and a non-operating shock of 40 G. A DIN-rail mounted module has an

operating shock of 20 G, a relay operating shock of 5 G, and a non-operating shock of 30 G.

It also has an operating vibration of 5 G at 10 to100 Hertz and its non-condensing relative humidity range

is 5 to 95%. This module has a removable terminal block (RTB) interface and an open-type enclosure. The

entire 1769-IR6 module measures approximately 1.38 x 3.43 x 4.65 inches. The 1769-IR6 module supports

an RTD and direct resistance signal measurement applications. This module digitally converts analog data

and it stores the converted data. Each of the 6 supported channels provides open-circuit and short-circuit as well as over- and under-range detection and indication.

The Allen-Bradley 1769-IR6 is an analog input module which belong to the Compact I/O product family.

This module is specifically used for Resistance Temperature Detectors (RTD) and Resistance signals. This

module may be used with MicroLogix 1500 and 1769 CompactLogix controllers. This module also supports

installation on distributed IO rack, provided that the communication adapters used are 1769-ADN DeviceNet and 1769-AENTR Ethernet adapter.
