Technical Specifications

Installation Guidelines

• Mounting: Install the module onto a standard S7-1500 DIN rail. Ensure the U-connector is correctly seated for power and data transmission.
• Grounding: Proper shield connection is mandatory for safety-related inputs to prevent electromagnetic interference (EMI).
• Wiring: Utilize the front connector for 16-channel wiring. Ensure proper wire gauging and ferrules to maintain secure connections.
• Thermal Management: Although rated for -30 degC to +60 degC, provide sufficient airflow to prevent hotspots in high-density rack configurations.
• Safety Precautions: Must be configured within a compatible Fail-safe PLC environment. Ensure the safety software parameters align with the connected physical sensors.
