Integrator note: fail-safe analog input
SIMATIC S7-1500 fail-safe analog input module, order code 6ES7536-1MF00-0AB0. It sits on the S7-1500 backplane as an F-module, reading 8 current-loop signals (0/4..20 mA) over PROFIsafe. Rated to SIL 3 (IEC 61508) and PL e (ISO 13849-1) – that means it carries the safety functions, not just monitors them. The 35 mm overall width is standard for the S7-1500 F-series; expect the same slot allocation and backplane power draw as a standard AI module.
Mounting & integration: checklist
F-AI 8xI 0(4)..20 mA PROFIsafe module, 35 mm width. Rated SIL 3 / PL e.
