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.
！ Caution when wiring for external
