VAS-4A16L-K31
AS-Interface Sicherheitsmonito
Descripción
The VAS-4A16L-K31 is a stainless steel safety monitor for 2 AS-Interface circuits in accordance with AS-Interface specification 3.0 with degree of protection IP20. The VAS-4A16LK31 has four inputs and four outputs. Two inputs are used for extended EDM device monitoring. Due to the 16 independent AS-Interface release circuits, several safe AS-Interface outputs are possible on one address. The K31 model is particularly suitable for installation in a control cabinet. Two safety relays provide a safe interface to the connected consumers. Address assignment and the transfer of the desired configuration can be performed using switches. Five LEDs located on the front panel indicate the current status of the AS-Interface segment. Local operation using the graphical display and the four switches allows all the functions covered on the other AS-Interface masters by AS-i Control Tools software to be visualized on the display. An RS 232 socket provides a way of exporting data relating to the network and operation directly from the safety monitor for extended local diagnosis purposes.
