The VAA-2E2A-KE1-S/E2 is an AS-Interface safety module with 2 safety-related inputs and 2 conventional outputs. A dual channel mechanical switch or in each case a single channel mechanical switch can be connected to the two safety-related inputs. The outputs are conventional electronic outputs, which may be loaded in total with 1 A (max. 0,5 A per output).
The housing, only 22.5 mm in width and 48.5 mm in height, takes up little place in the switch cabinet. The module features an integrated addressing jack is mounted by snapping onto the 35 mm DIN rail in accordance with EN 50022. Plug-in terminals are used for connection. A 4-way terminal block (black) is used for the inputs. The AS-Interface is connected via a double terminal block (yellow).
The current switching state of each channel is indicated by an LED, located on the module's top side. Similarly, an LED is provided to monitor the AS-Interface communication and to indicate that the module has the address 0. If a communication error occurs, the outputs are de-energized (only P0=1).
When single channel force-directed mechanical switches are connected, up to Performance level c in accordance with EN ISO 13849-1 can be achieved, given the appropriate wiring and selection of switch.
When a two-channel force-directed mechanical switch is connected, up to Performance level e in accordance with EN ISO 13849-1 can be achieved, given the appropriate wiring and selection of switch.
As per approval in accordance with IEC 61508 and IEC 62061 up to SIL 3 can be achieved.
Both inputs of the module are assigned. The two channels of the mechanical switch are monitored for a cross circuit. LEDs are also provided to indicate AS-Interface voltage and external power supply.
