Specification

SEODescription

The **6ES7222-1HH32-0XB0** is a **Siemens S7-222 Relay Module** designed for the **S7-200** series PLCs, offering **8-channel digital relay outputs** (5-30V DC/120-230V AC) for switching high-current loads. It operates within a **24V DC supply voltage** and supports ambient temperatures from **0°C to 55°C**, making it suitable for industrial automation, manufacturing, and process control applications. The module integrates seamlessly with the S7-200 CPU via direct expansion, allowing integration of up to **7 additional modules** for system scalability. While its relay contacts provide flexible voltage compatibility and isolation, mechanical wear limits high-frequency switching reliability. The module lacks onboard communication interfaces but relies on the CPU’s **RS-485 (PPI/MPI)** for network connectivity. Ideal for cost-sensitive projects requiring robust relay-based control in environments like packaging, HVAC, or machinery.
