2 Product description of safety module CAMC-G-S3
Internal brake activation at the output [X6] is suitable for clamping units of holding brakes
with 24 V and a current consumption of max. 2 A è Technical data of brake output in the
hardware description GDCP-CMMP-AS-G3-HW-...
Alternatively, the clamping unit or holding brake can be activated via a safe digital output
(DOUT40 to DOUT42) and an external brake switching device è see examples in Section
3.3.5 and 3.3.6.
Timing diagram
Fig. 2.33 shows an example of the runtime performance when the internal brake output [X6] is switched
off and on again. The test pulses for the energised clamping unit or holding brake (vented) are also
shown. They are temporally offset.
