Details: VAA-2E2A-G12-SAJ/EA2L


The VAA-2E2A-G12-SAJ/EA2L is an AS-Interface safety module with 2 safety-related inputs and 2 conventional outputs. A two-channel mechanical switch on both of the safety - related inputs or a one-channel mechanical switch on each one can be connected. The outputs are conventional electronic outputs which can be energized with a total of 4 A (max. 2A per output).

The solid housing permits fast mounting without tools as well as easy removal without tools. The stainless steel shell and the cast housing ensure durability and a high protection category.

The connection to the AS interface cable is achieved via penetration technology in the integrated flat cable. The insert for the flat cables can be turned in two orientations.

All connections to inputs are implemented via metal inserts for high stability. The connection to the sensors is achieved via a M12 x 1 circular connector with SPEEDCON quick locking option.

To indicate the current switching state there is an LED for each channel fitted to the top of the module. An LED for monitoring the AS interface communication and for displaying that the module has the address 0 is also available. For communiction errors the power is switched off the outputs (only for P1=1).

According to approval the module can be used up to category 4/PL e as per ISO 13849-1, SIL 3 as per EN/IEC 61508 wiht the use of both input channels.

When using two one-channel switches the module can be used up to category 2/PL c as per ISO 13849-1, SIL 2 as per EN/IEC 61508.

Both channels of the mechanical switch are monitored for cross connection. One LED shows the voltage of the AS-Interface and another the external voltage supply.
