Siemens SIMATIC S7-400 SM 431 Analog Input Module | 8 AI | 14-Bit | 6ES7431-1KF20-0AB0

SIMATIC S7-400, analog input SM 431, isolated 8 AI, resolution 14 bit, U/IResistor 8 AI, cycle time 0.416 ms (6ES74311KF200AB0)

Q: Does this module support RTD (Resistance Temperature Detectors)?A: This specific model is designed for Voltage, Current, and Resistance. For dedicated RTD sensors like Pt100, the SM 431 (6ES7431-7KF00-0AB0) is usually preferred.

Q: What is the benefit of the 14-bit resolution?A: It allows the PLC to detect much finer changes in the analog signal, which is essential for high-precision control loops.

Q: Is the front connector included?A: No, like most S7-400 modules, the 48-pin front connector must be ordered separately.
