Details and context
Piconet is Turck's modular IP67 fieldbus I/O system for harsh industrial sites, using IP-Link—a fiber-optic chain—for daisy-chaining modules without control cabinets. This cuts wiring and costs in automation.[[3]](https://www.folsgaard.com/en-gb/about-us/news-events/news/news/manufacturing-industry/fieldbus-the-backbone-of-the-new-generation-of-machines-2)
The SNNE-0002D-0002 adds PWM outputs for speed control of motors/valves or lighting dimming, with high current handling for loads like solenoids. Folsgaard resells it in their online catalogue under interface technology.[[2]](https://tipteh.serv.si/en/download/15759)
Detailed specs come from Turck datasheets, as Folsgaard's page shows mostly placeholders; supports resistive/inductive loads with derating for heat.
Why it matters
Fieldbus modules like this advance cabinet-free automation, vital for flexible manufacturing. Engineers get reliable PWM in tough spots, easing integration with EtherNet/IP or PROFINET gateways. Watch for system expansions or updated manuals from Turck/Folsgaard.
