Parallel Input/Output Unit - Mitsubishi RV-3SJ Series Standard Specifications Manual

3 Controller

3.7 Parallel input/output unit

・ A parallel input/output card is mounted as a standard in the controller's control unit.
・ The external input/output circuit specifications are shown in
・ The correspondence of the external input/output connector pin No. and the colors of the connected "external
input/output cable" wires (separate option) is as shown in
I/O cable" for details of external I/O cable.
・ Pin Nos. described as both general-purpose signal and dedicated signal can be shared.
・ The other dedicated input/output signals that are not assigned can be assigned to required general-purpose
input/output pins when creating the program.
・If the standard inputs and outputs are insufficient, install the parallel input/output unit connection option outside
the controller.

[Caution] When connecting the phototransistor output to the input circuit, be sure to allocate an input current of
approximately 7 mA at 24 VDC. Especially when using a photo diode and a phototransistor (sensor)
away from each other, it is recommended to verify the current that can be carried in the design stage.

The output circuit protective fuses prevent failure in case of load short-circuit and
improper connections. Please do not connect loads that cause the current to exceed
the maximum rated current. If the maximum rated current is exceeded, the internal
transistors may be damaged.
