I/O module
24 VDC "10% supplied
from the power supply
connector CPD1. The
allowance of "10%
should include
instantaneous voltage
and ripple voltage.
0.35A The total power
consumption of
DI points is
included.
(This is true
when all general
DI points are
turned on.)
The power
consumption of
DO points is not
included.
DI (input signal) specifications
(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 drop
2 V or less
(including cable voltage drop)
Delay Receiver delay: Max. 2 ms
The time required for I/O Link transmission
between the CNC and I/O module (max. 2 ms +
CNC ladder scan cycle) must also be taken into
account.
(Matrix input signal)
Contact rating 6 VDC, 2 mA or more
Open circuit intercontact
leakage current
0.2 mA or less (at 6 V)
Closed circuit intercontact
voltage drop
0.9 V or less (with a current of 1 mA)
Delay The maximum matrix period of 16 ms, the
maximum time of I/O Link transfer between CNC
and I/O module of 2 ms, and the ladder scanning
period (by CNC) must be considered.
NOTE
When detour prevention diodes are used, the voltage drop
across closed contacts indicated above must be
maintained, including the diode voltage drop.
