SIMATIC S7-400 / S7-400H / S7-400F/FH

SIMATIC S7-400 is the powerful PLC for mid to high-end performance ranges, serving the needs for even the most demanding tasks, at the same time allowing customisation with a comprehensive range of special function modules for optimal adaptation to the automation task.

S7-400H is the fault-tolerant automation system with redundant configuration for applications with high failure safety requirements, particularly for the scenario when high restart costs, expensive downtimes, little supervision, and complex maintenance occurs.

S7-400F/FH is the failsafe automation system for plant with high safety requirements, at the same time compling to the stringent safety requirements up to SIL 3 to IEC 61508, AK6 to DIN V 19250 and Cat. 4 to EN 954-1.
