VBA-4E3A-CB-E/E2-SAS-Interface printed circuit board

Technical data Function

General specifications

The VBA-4E3A-CB-E/E2-S AS-Interfacecoupling module is the circuit board solutionfor an AS-Interface slave. The module is ideal for integration into customer-specificelectronics, e.g. keypads, actuators, etc.The circuit board is supplied by the AS-Inter-face. The inputs and outputs are short-circuitand overload-proof.

Slave type A/B slave
