VAA-4EA-CB-E/E2-SAS-Interface printed circuit board

Technical data Function

General specifications

The VAA-4EA-CB-E/E2-S AS-Interface cou-pling module is the circuit board solution foran AS-Interface slave. The module is ideal for integration into customer-specific elec-tronics, e.g. keypads, suppliers of actuators, etc. The cir-cuit board is supplied by the AS-Interface.The inputs and outputs are short-circuit andoverload-proof.
