Siemens SIMATIC S7-1500 Analog Input Module | AI 8xU/I/RTD/TC ST | 6ES7531-7KF00-0AB0

Q: Does this module include the front connector?A: No, like most 35mm S7-1500 modules, the front connector (screw or push-in) must be ordered separately.

Q: How many RTD sensors can I connect?A: While it has 8 channels, it typically supports up to 4 channels for RTD measurement when using 4-wire connections.

Q: What is the benefit of the "Standard" (ST) line?A: The ST line offers a perfect balance of high-end features (like 16-bit resolution and hardware interrupts) without the higher cost of the High Feature (HF) modules.
