B–63523EN/03
9. CONNECTION TO FANUC I/O Link
351
Contact capacity 30 VDC. 16 mA or more
Leakage current between
contacts when opened
1 mA or less (26.4 V)
Voltage decrease between
contacts when closed
2 V or less (including voltage drop in the cable)
Delay The receiver delay is 2 ms (maximum). In addition,
[I/O Link transfer time between CNC and machine
operator’s panel (2 ms maximum)] + [ladder scan
period (depending on CNC)] must be considered.
Maximum load current
when ON
200 mA or less including momentary variations
Saturation voltage when
ON
1 V (maximum) when the load current is 200 mA
Withstand voltage 24 V +20% or less including momentary variations
Leakage current when OFF 20 µA or less
Delay time The driver delay is 50 s (maximum). In addition,
[I/O Link transfer time between CNC and I/O
module (2 ms maximum)] + [ladder scan period
(depending on CNC)] needs to be considered.
NOTE
The maximum current for each of the DOCOM power supply
pins for the DO signals must not exceed 0.7 A.
