Each channel supports thermocouple types B, C, E, J, K, N, R, S, and T, with configurable filtering and update timing parameters. Channel isolation separates field input signals from each other and from the ControlLogix backplane.\u003c\/p\u003e\n\u003cp\u003eThe module uses 16-bit analog conversion resolution with selectable data representation modes. Temperature values can be transferred through IEEE 32-bit floating point formatting, while millivolt signals can be processed using integer mode.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications for Industrial Control Integration\u003c\/h3\u003e\n\u003cp\u003eThe module communicates through the ControlLogix chassis backplane and supports standard ControlLogix I\/O configuration. The backplane current requirements are 250 mA at 5.1 VDC and 125 mA at 24 VDC. The removable terminal block interface supports field wiring termination through compatible 1756 series terminal blocks.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What thermocouple types are supported by the 1756-IT6I\/A module?\u003c\/strong\u003e\u003cbr\u003eA: The module supports B, C, E, J, K, N, R, S, and T thermocouple sensor types.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the 1756-IT6I\/A provide electrical isolation between input channels?\u003c\/strong\u003e\u003cbr\u003eA: Yes.
