The Siemens 6ES5244-3AA21 is a SIMATIC S5 IP244B temperature control module designed for compatibility with SIMATIC S5-115U, S5-135U, and S5-155U programmable logic controller systems. This module features built-in self-tuning capabilities and supports analog inputs for precise closed-loop temperature regulation in industrial process environments. Engineered with a high degree of interference suppression, it ensures reliable and accurate signal processing even in electrically noisy factory settings. Built with physical dimensions of 11.55 x 5.30 x 12.50 cm and a weight of 0.48 kg, it serves as a robust solution for legacy system maintenance. Although classified as an obsolete product phase with a designated successor model (6ES5244-3AA22), it remains a critical component for supporting existing S5 installations.
