Power supply of
the
STO function
For the power supply of the STO function on connector X2 a 24 V power supply unit is
required, which corresponds with the SELV/PELV standards according EN 50178.
Voltage: 24V
DC
-15 %/+20 %
Inputs
STO function
The inputs of connector X2 have been designed according IEC 61131.
The input levels are as follows in case of 24 V DC power supply:
The maximum length of the cable is 30 m.
The safe inputs are designed for an operation with sensors providing OSSD outputs. The
maximum test pulse length of 1 ms must not be exceeded.
Both inputs STO A and STO B are necessary for the safety function STO and must be
activated separately. If both inputs are activated by one cable, the fault exclusion short-
circuit according IEC 61800-5-2 appendix D must be considered.
Outputs
