ABB DSQC100 YB161102-AA DSQC233 module
Technical data of product parameters
With the single-channel control of the STO (SIL2/PLd) safety function, both switch-off
pathsDSQC100 YB161102-AA DSQC233-Enable and STO2-Enable are switched by one output of a safety switching
device (e.g. safety relay), see example p. 42.
In case of single channel usage of STO, erroneous engaging will not be recognized. Therefore the output of the control must be supervised for possible malfunction.
SIL2/PLd Dual Channel Control
With the dual-channel control of theDSQC100 YB161102-AA DSQC233safety function, the switch-off paths
STO1-Enable andDSQC100 YB161102-AA DSQC233-Enable are switched separately by two outputs of a safety switching device (e.g. safety relay), see example on p. 43.
SIL3/PLe Dual Channel Control
With the dual-channel control of the STO safety function, the switch-off paths
STO1-Enable and DSQC100 YB161102-AA DSQC233Enable are switched separately by two outputs of a safety control, see example on p. 44.
To achieve PL e or SIL CL3, the safe switching of the pulse inhibitor must be tested periodically by analyzing the feedback signal from the safety control ( p. 46). The feedback
signal is placed at one of the digital outputs DIGITAL-OUTx
of the S700 with the ASCII command OxMODE70.
When wiring the STO inputs within one enclosure it must be paid attention to the fact that
the used cables and the enclosure meet the requirements of IEC 60204-1.
If the wiring leads outside the demanded enclosure, the cables must be laid durably
(firmly), and protected from outside damage (see chapter 5.9.3).
If STO function is not needed in the application, then the inputs STO1-ENABLE and
STO2-ENABLE must be connected directly with +24VDC. STO is passed by now and
cannot be used. Now the servo amplifier is not a safety component referring to the EC
Machine Directive
