R. STAHL 9468/32-08-11 IS1+ HART Analog Universal I/O Module

Product Description

The 9468/32-08-11 is an 8-channel intrinsically safe analog universal I/O module of R. STAHL IS1+ Remote I/O system, certified for Zone 1 / Div.1 hazardous areas. Each channel can be flexibly configured as analog input or output, supporting bidirectional HART communication. It connects 2-wire, 3-wire and 4-wire HART transmitters, valve positioners and 4-20mA field devices, featuring hot-swap function under powered condition. It provides galvanic isolation and individual wire break / short-circuit monitoring for every channel.
