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.
