5.5 AS interface bus connection
The AS1 module (4 inputs / 4 outputs) corresponds to the requirements of the new AS interface according to
specification 2.1. As with the control electronics of the SK 1xxE, this assembly is entirely powered by the AS
interface. The inputs and outputs are resistant to short circuit and overload
A watchdog function has been integrated that switches the outputs current less if no communication takes
place on the AS interface line.
Up to 3 circuit elements can be queried with the inputs. A signal lamp can be activated by the output whereby
the energy is supplied from the AS interface system. The assignment for the control signals of the SK 1xxE is
included in the table below. Apart from the motor activation, up to 3 additional sensors can be connected to
M12 sockets and read. Together, they may draw max. 130 mA current.
