TNT 35

Test Monitoring Unit for Type 2 Sensors

Every 2 seconds, the test monitoring unit TNT 35 performs a periodic test on the protective function of the connected testable sensor, without interfering in the production process of the safeguarded machine.

This rapid succession of periodic functional tests ensures a maximum of Type 2 functional safety.

Advantages
