Switching thresholds for voltage and current
NOTICE!
If electronic sensors such as safety light curtains are used, it must be ensured that
these components can provide the input currents required for the supply of the Safety
Module (SAF-001).
NOTICE!
If electronic sensors with OSSD outputs are used, it must be considered that the
maximum test pulse width of 2 ms is not exceeded.
NOTICE!
If the STO connections are connected to the 24V supply system external safety
devices against surge voltages are required.
Inputs STO_1A_24V, STO_1B_24V, STO_2A_24V and STO_2B_24V
Voltage and current switching thresholds (on input side) of the inputs STO_1A_24V,
STO_1B_24V, STO_2A_24V and STO_2B_24V:
Voltage / Current
U high max
U high min
U low max
U low min
I high max eff
I high min eff
I low max eff
Input capacitance
Inputs FS_1_24V and FS_2_24V (restart axis 1 and 2)
The inputs FS_1_24V and FS_2_24V (restart axis 1 and 2) are in the normal range for
digital inputs according to type 1 (EN 61131-2).
