5.6.6 Input/Output wiring schematic
The input signals are the messages transmitted to the Controller from the external device.
These signals can be generated by push button, Limit Switch, Relay Board connection or
Proximity Switch, etc.
The output signals are the messages transmitted to external working machine from the
Controller, which are used to drive the Relay of the Working Machine and the LED
display of the Controller.
Input/Output Interface
The Controller must link with other accessories through SIO Module Board so as to control the
actions of external I/O, power output and axis control module.
I/O Connect Board PC Board No. H6DOO 6
Fig 5-28
1. I/O connect board controls 24 input terminals and 16 output terminals.
2. Output control is by 0V output.
3. An INPUT can be of NPN type or PNP type.
4. When NPN and PNP are in use at the same time,
(1) NPN the input voltage at I is 0V.
(2) PNP the input voltage at I is 24V.
5. Input current at I: 3.6mA
6. Output current at O: 100mA (H6D\CPU\V6_1 : 250mA).
