Minimum conversion time Ladder scan period of the connected CNC
1) Basic, expansion A, and expansion B
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 momentary values)
Leakage current in OFF state 20 mA or less
Delay Driver delay: Max. 50 ms
The time for I/O Link transmission between the
Power Mate and I/O module (max. 2 ms + ladder
scan cycle) must also be taken into account.
2) Extended C
DO (output signal specification)
Number of points 16 (per module)
ON–time maximum
load current
2A per point
12A in the entire module (DO: 16 points) (including
instantaneous current)
Withstand voltage 24 V + 20% or less (including instantaneous voltage)
OFF–time leak current 100 µA or less
Delay time The I/O Link transfer time of 2 ms (max.) plus the ladder
scan period (due to the CNC) must be considered.
