6ES7331-1KF02-0AB0 is an analog input module in the Siemens SIMATIC S7-300 series, model SM 331. This module has potential isolation function, with 8 analog input channels and supports multiple input types, including voltage (0 to+10V, 1V to 5V, etc.), current (0 to 20mA, 4mA to 20mA, etc.), resistance (0 to 600 Ω, 0 to 6000 Ω), and thermistor (Pt100, Ni100, Ni1000, etc.). It has a conversion time of 66ms, a resolution of up to 13 bits, and a parameterized integration time (including four levels of 2.5ms, 16.7ms, 20ms, and 100ms).

In terms of physical characteristics, the module size is 40mm × 125mm × 117mm, weighing approximately 250g, and connected using a 40 pin front plug. In terms of power requirements, it comes from the DC 5V of the backplane bus, with a maximum current of 90mA and a typical power loss of 0.4W.

In addition, the module also supports diagnostic interrupt function, which can monitor the running status of the module in real time and record the last 100 fault events for easy troubleshooting. At the same time, it also has user program password protection function to ensure the security and reliability of the system. This module is widely used in manufacturing, process control, building automation and other fields, and can be used in conjunction with other modules in the Siemens S7-300 series to build efficient and stable automation control systems.
