PILZ SDD Series Safety Device Diagnostics products give maintenance engineers direct visibility into the operational status of connected PILZ safety devices, reducing troubleshooting time and helping improve machine availability. A fieldbus module — available in Modbus/TCP, EtherNet/IP, and PROFINET variants — collects advanced diagnostic data from PSENcode sensors through junction interface modules and feeds it into the plant network in real time, so faults can be identified and resolved without manual inspection of individual field devices.

Key Features

• Safety Device Diagnostics system for real-time diagnostic access to compatible PILZ safety devices such as PSENcode sensors
• Fieldbus module variants support Modbus/TCP, EtherNet/IP, and PROFINET communication for integration into plant networks
• Fieldbus modules include 2 RJ45 ports for flexible network topology integration
• Passive junction interface modules support connection of up to 4 or up to 8 PSENcode sensors per module, with up to 16 subscribers where specified
• Diagnostic data helps maintenance teams identify device faults, reduce service calls, and minimize unplanned downtime
• Screw-type and spring-loaded terminal set accessories available for compatible 45 mm SDD housings
• Item-specific specifications vary by module type, communication protocol, subscriber capacity, sensor connection count, terminal style, and housing compatibility
