Information About 1769-IT6

The 1769-IT6 belongs to the Compact I/O family and supports six configurable channels that can accept thermocouple types J, K, T, E, R, S, B, N, and C, as well as millivolt ranges of ±10 mV and ±50 mV. It uses a Delta-Sigma A/D converter, with response speed dependent on filter settings, and automatically calibrates at power-up or on a programmed interval. The module includes advanced diagnostics such as open-circuit, short-circuit, over-range, and under-range detection for each channel. It consumes 100 mA at 5 VDC and 40 mA at 24 VDC, and communicates with the controller through the backplane. Selectable input filters (10 Hz to 1 kHz) help minimize noise and stabilize readings. With measurement ranges from –270 °C up to +2315 °C (depending on thermocouple type), the 1769-IT6 is well-suited for industrial temperature applications, such as furnaces, HVAC, and process monitoring.
