Description

Two switching outputs, one of them programmable as IO-Link and one as analogue output
Red/green display for clear identification of the acceptable range
The process connection can be rotated for optimum alignment
With long-term stability thanks to high overload protection
Robust design for use in harsh industrial environments
Convenient operation via buttons or parameter setting via IO-Link
