3.3.7 EZJ127 board (I/O board)
[Function]
- The I/F signal with the conveyer is connected.
Output signal: Ready, Fault, Warning, Printing-in-progress/Print-complete, On-line,
Universal output 1, Universal output 2
Input signal: Print target detector, Print stop, Reciprocative printing,
Encoder (for product speed matching),
Deflection voltage ON/OFF,
Run, Reset ,Stop
- External communication: RS-232C connection
- I/O board for UX- D/E is EZJ127A and I/O board for UX-B is EZJ127B.
In order to add the option (Addition of standard communication and input/output
signal) for UX-B, it is necessary to change the I/O board from EZJ127B to EZJ127A.
Regarding the replacement procedure to add the option, refer to the following
procedure.

With respect to the wiring,
refer to
Technical manual
“
4 Connection of signals”.
- Faulty wiring causes the substrate breakdown. Before wiring, be sure to confirm the
terminal signal.
- Before wiring, be sure to turn off the power.
