Safety sensor
•
Capacity requirement per safety output (source) channel: 5 × No. of connected axes (mA)
•
24 VDC supply allowable voltage: 24 V±15 %
•
Maximum No. of connectable axes: 8
*
The number of connectable axes shown in the gure is for reference only.
EDM output depends on external circuit because saturated voltage Vce (sat) of approx.
1.0 V in the built-in photocoupler varies with collector current.
Amount of current owing to SF input is 5 mA per circuit.
When increasing the number of axes to be connected, make sure that required amount
of current does not exceed the maximum output current of the safety controller.
