It snaps onto the DIN rail alongside the CPU and connects through the ribbon-cable bus connector — no separate fieldbus node, no IP address to set. Each relay output switches up to 2 A, so it handles small motor contactors, solenoid valves, and indicator loads directly. The relay form gives you isolation between the PLC backplane and the field wiring. ## Relay output rating in context Eight relay outputs at 2 A each means the module can switch up to 16 A total across all channels, but the 2 A per-channel ceiling is the limit for any single load. That 2 A at 230 VAC (resistive) or 2 A at 24 VDC (resistive) covers most pilot-duty loads in a control panel — think contactor coils, signal lamps, and small valve actuators. Because these are relay outputs, the switching frequency is lower than a solid-state output — you would not use this module for a high-speed pick-and-place or a PWM valve. But for on/off control of pumps, conveyors, and batch valves on a bottling or canning line, the relay gives you a clean open and the isolation the field wiring needs.","metaTitle":"Siemens 6ES7222-1HF20-0XA0 EM 222, 8 Relay Outputs 2A","metaDescription":"Siemens EM 222 expansion module, 8 relay outputs rated 2A each.
