The Siemens SIMATIC ET 200SP HA DQ 4xRelay NO/NC 230V AC/DC HA (6DL1135-6UD00-0PK0) is a 4-channel relay output module for the ET 200SP High Availability distributed I/O system. Each channel provides changeover (Form C) relay contacts capable of switching up to 230V AC or 30V DC at 2A. The module features galvanic isolation between channels and the backplane bus, relay coil open circuit detection, and status LEDs per channel. Designed for high availability systems, it supports safety-oriented shutdown when required by the application context. Ideal for switching high-voltage AC loads, motor starters, solenoid valves, and alarm devices in process automation environments where galvanic isolation and high switching capacity are required.
