Dual-channel control of magnetic safety switches to EN 60947-5-3
(see Fig. 15)
• Wire breakage and earth leakage in the control circuits are detected.
• Cross-wire shorts between the control circuits are detected.
• For the safety circuits monitoring, the magnetic safety sensors may be
designed as "simple electrical apparatus".

The connection of magnetic safety switches to the SRB
101EXi-1R
safety-monitoring module is only admitted when the require-
ments of
the standard EN 60947-5-3 are observed.
As the technical data are regarded, the following minimum
requirements must be met:
– switching capacity: min. 500 mW
– switching voltage: min. 33.6 VDC
– switching current: min. 57 mA
