Function: VAA-2E2A-KE1-S/E2

The VAA-2E2A-KE1-SE is an AS-Interface safety module with two safety-related inputs and two outputs. A self-testing electronic protective system can be connected to the two safety-related inputs. The outputs are conventional electronic outputs that can be loaded to a total of 3 A (max. 1 A per output).

The housing is only 22.5 mm wide and 48.5 mm tall and takes up little space in the switch cabinet. A snap-on function mounts the module onto the 35 mm mounting strip in line with EN 50022. An addressing socket is integrated in the module. The connection is made via plug-in terminals. A four-way (black) terminal block is used for the inputs. The AS-Interface is connected via a two-way (yellow) terminal block.

Each channel has an LED mounted on the top side of the module to display the current switching status. There is an LED for monitoring AS-Interface communication and for displaying that the module has the address 0. In the event of communication faults, the outputs are disconnected from the power supply (only for P0=1).

If a noncontact protective system is connected, the module can be upgraded to performance level e in accordance with EN ISO 13849-1 if wired appropriately. As per the approval in accordance with EN 62061, a Safety Integrity Level of up to SIL 3 can be reached.
