Details: VBA-2E1A-CB-N/E2-S


The AS-Interface I/O Module VBA-2E1A-CB-N/E2-S is an AS-Interface printed circuit board module with 2 inputs and one output. NAMUR sensors can be connected to the inputs. The printed circuit board module is designed for the integration into a customer-specific electronics.

The current switching state of each input channel is indicated by a yellow LED. The electronic output has an overload limit as well as a lead breakage and short circuit monitoring.

Another LED indicates operating voltage and communication or peripheral failures (short-circuit, lead breakage). In case of a peripheral failure the communication via AS-Interface continues.

The printed circuit board is powered completely via AS-Interface. The inputs and the output are short-circuit and overload-proof. Screw terminals are used for connection.
