Details

The AWAX28XXL has been designed to monitor mechanical switches, switches using the process ACOTOM (BTI’s trademark), or the emergency push buttons with 2 NC lines at least. This module has 9 safety outputs(8 NO + 1 NC), each one with a switching capacity of AC1 8A/250V. The safety relay can be used in applications up to Kat4 PLe acc. EN ISO 13849 or Sil3 acc. EN 62061. The safety outputs of AWAX28XXL must be tested by the user in regular test intervals unless it is cyclically tested by the application itself where it is implemented. The test interval depends typically on the safety analysis of the global system where it is implemented. It is recommended to test the system at least once a year.
