Product Description

The Siemens S7-200 SM222 (6ES7222-1HF22 module) is a Digital Output Relay Module designed for industrial automation systems. It features 8 relay-based outputs, providing flexible control for AC/DC loads with a switching capacity of 2A per channel. The module operates at 24V DC supply voltage and supports integration into S7-200 PLC systems, enabling direct connection of up to 7 expansion modules via the base unit. With a wide operating temperature range of 0°C to 55°C, it suits applications in manufacturing, machinery, and process industries. Key advantages include robust relay switching, galvanic isolation, and easy installation, while its mechanical relay design may limit high-speed switching cycles. The module lacks onboard communication interfaces but interfaces via the S7-200 system bus. Compliance with industrial EMC standards ensures reliable operation in harsh environments.
