150
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 required 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.
NOTE
Ensure that the maximum current per DOCOM pin (DO
power supply pin) does not exceed 0.7 A.
DO signal reaction to a system alarm
If a system alarm occurs in the CNC using the operator’s panel I/O
module, or if I/O Link communication between the Power Mate and
operator’s panel I/O module fails, all the DO signals of the I/O module
are turned off. Therefore, sufficient care is necessary when setting up the
machine sequence. Also, the same phenomenon occurs if the power to
the Power Mate or the I/O module is turned off.
Address allocation
For the operator’s panel I/O module, I/O addresses are mapped as follows.
