SI-Safety module
The SI-Safety module is a compact safety controller with integrated drive monitoring for
an axis. This device can be programmed at will to assure safe processing. This
encompasses the EMERGENCY STOP buttons, two-handed operation, light grids,
operating mode selector switches etc., as well as drive-related safety functions. For a
large number of input devices, pre-configured modules are available for safety-related
pre-processing of signals. The same applies to safety functions for drive unit monitoring.

.
The basic version of this device has safe inputs for a maximum of five input elements
and three disengagement channels.
For 'safe' recording of speed and/or positions, single sensor solutions (Incremental, SIN/
COS, Proxi-Switch) as well as 2-sensor solutions (e.g. Incremental or SSI and
Incremental.) are supported.
