Ezj127 Board (I/O Board) - Hitachi IJ RX2 Service Manual

3.3.7 EZJ127 board (I/O board)

With respect to the wiring,
refer to Technical manual
"4 Connection of signals".
[Connection to the external connection terminal block (TB1) ]
(Note 1): Available supply current for print target detector and encoder is up to 100mA in total.
[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),
Run, Reset ,Stop
- External communication: RS-232C connection
- I/O board for RX2- S is EZJ127A and I/O board for RX2-B is EZJ127B.
In order to add the option (Addition of standard communication and input/output
signal) for RX2-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.
