About 1769-IT6

The Allen Bradley 1769-IT6 thermocouple/mV input module is a compact device that can measure thermocouple and millivolt signals. These measured values are digitally converted and stored as analog data in any combination of up to six thermocouples or millivolt analog sensors. Provide over range, under range, open circuit detection and indication.

The 1769-IT6 compact input module has 6 input channels and 2 CJC sensors. It has a Delta Sigma converter type, and its response speed per channel depends on the input filter and configuration. It communicates with the controller through a bus interface and also receives power from the 5-24V DC system power supply. The maximum current of the 1769-IT6 module is 100 mA at 5 VDC and 40 mA at 24 VDC. When powered on and the channel is enabled, this input module performs automatic calibration. Automatic calibration can also be programmed to run every five minutes.

This module is particularly compatible with temperature measurement, such as -210…+1200 ° C for J-type temperatures, -270…+1370 ° C for K-type, -270…+400 ° C for T-type, -270…+1000 ° C for E-type, 0…+1768 ° C for R-type, 0…+1768 ° C for S-type,+300…+1300 ° C for B-type thermocouples, and 0…+2315 ° C for C-type thermocouples. Each analog input can be configured as engineering units, PID scaling, and raw/proportional data.

This module is designed to detect open circuit, short circuit, over range, and under range detection for each of the six (6) channels. Optional input filters can also be used for stable measurements. The selectable input filters include 10 Hz, 50 Hz, 60 Hz, 250 Hz, 500 Hz, and 1 kHz.
