AUD-LA: Adapter for TAC b3887 and TAC i2887 digital outputs

ESAC AUD-LA adapter converts two binary triac outputs into two relay outputs.
The plug and play installation considerably reduces wiring time and accessory material waste.


  • plug and play on the controller
  • stackable
  • non-simultaneous switch

The ESAC AUD-LA adapter is designed to convert an electrical signal for the outputs of the controllers on which it is placed.
With this accessory it’s possible to directly use outputs to convert two triac outputs into two relay outputs.
The ESAC AUD-LA can be installed on TAC b3/i2 887 modules.
