Allen-Bradley 1756-IRT8I is a ControlLogix analog input module with eight (8) configurable channels for resistance temperature detector (RTD), thermocouple, and millivolt inputs.

The module realizes high resolution analog-to-digital conversion by Sigma Delta method. The converted data is saved to IEEE 32-bit floating point. Human Machine interfaces (HMI), supervisory control and Data acquisition (SCADA), and distributed control systems (DCS) are ideal for accessing the converted data. In addition to computer-based systems, signal data can be used for computation, as well as process variables (PVS) for controllers, such as ratio + integral + differential (PID).

The module is capable of open circuit detection with thermocouple input and 3-wire RTD detection time of 2 seconds and 4-wire RTD detection time of 5 seconds.

The input range supported by this module is 1-500? 2-1000? , 4-2000? - 8-4000? And -100 to 100 millivolts. The total resolution of the module is 24 bits. The actual resolution is 0... A: 510? :0.06 m? / Count 0... 1020? :0.12 meters? / Count 0... 2040? :0.25 meters? / Count 0... 4080? :0.50 meters? /count -101… 101 mV: 0.01? v/ count.

Supported thermocouple types include Type B, Type C, Type D, Type E, Type J, Type K, Type N, Type R, Type S, type T, TXK/XK (L) thermocouples with ITS-90 linearization. Compatible RTD sensors include 100? PT 385,20? PT 385500? PT 385,1000? PT 385,100? PT 3916,20? PT 3916,500? PT 3916,1000? PT 3916,10? CU 427,120? Ni 672,100? Ni 618,120? Ni 618,200? NI 618 and 200? NI 618. Compatible millivolt signals should be in the range of -100 to 100 millivolts.
