R. STAHL 9475/32-08-52 IS1+ Digital Input Module

Product Description

The 9475/32-08-52 is an 8-channel intrinsically safe digital input module belonging to the R. STAHL IS1+ remote I/O system, certified for Zone 1 hazardous locations. It is designed to collect dry contact, Namur and 24V DC binary signals from field explosion-proof sensors and switches. Each channel provides independent intrinsic safety protection, open-circuit and short-circuit diagnosis, and supports hot-swap operation while energized. It communicates with the IS1+ CPM controller via the internal BusRail backplane bus.
