cluded.
(General–purpose input signal)
Contact rating 30 VDC, 16 mA or more
Open circuit intercontact leakage
current
1 mA or less (at 26.4 V)
Closed circuit intercontact voltage

2 V or less
(including cable voltage drop)
Delay Receiver delay: Max. 2 ms
The time required for I/O Link transmis-
sion between the CNC and I/O module
(max. 2 ms + CNC ladder scan cycle)
must also be taken into account.
Maximum load current in ON state 200 mA or less (including momentary
current)
Saturation voltage in ON state Max. 1 V (when load current is 200
mA)
Withstand voltage 24 V +20% or less (including momen-
tary values)
Leakage current in OFF state 20 mA or less
Delay Driver delay: Max. 50 ms
The time required for I/O Link transmis-
sion between the CNC and I/O module
(max. 2 ms + CNC ladder scan cycle)
must also be taken into account.
NOTE
Ensure that the maximum current per DOCOM pin (DO
power supply pin) does not exceed 0.7 A.
