Siemens is expanding its proven Simatic S7-400 product line to include solutions specifically for use in harsh ambient conditions. The high-availability Simatic S7-400H CPUs (Central Processing Units) are now manufactured as standard with conformal coating that complies with ISA-S71.04 severity level G3 (standard for corrosion-resistant design of power supplies).

This special printed circuit board coating considerably extends the range of applications for the controller without additional costs. In addition, Siemens has attained the security certificate CNCERT (China) for the communication robustness of the Simatic S7-400H, which recognizes the high security standard of the controller.

Simatic S7-400 controllers from Siemens offer a high degree of investment protection. Siemens is therefore continuously enhancing this product line. The consistent automation system is particularly well-suited for data-intensive tasks in the process industry.

Thanks to the new coating, many automation tasks can be implemented easily in harsh industrial environments without additional measures. High processing speeds and deterministic response times also ensure short machine cycle times for high-speed machines in the manufacturing industry.
