Note

The upper alarm value is compliant with NAMUR NE 43, but the lower alarm value is not.

If using in a system with NAMUR NE 43 compatibility, the high alarm value may be an appropriate choice.

Other circuits in the digital level controller provide reverse polarity protection, transient power surge protection, and
electromagnetic interference (EMI) protection.
