6. CONNECTION OF I/O UNITS TO
D For power cable J24, use a wire of at least 30/0.18 (0.75 mm
D For information about the connection between the control unit and I/O
card, see Subsec. 6.2.2.
D To connect with the machine, use a multi–core shielded cable.
A66L–0001–0041 (70/0.18, 20 conductors)
A66L–0001–0042 (70/0.18, 50 conductors)
D On the I/O card, the shield of the cable used to connect the machine
must be clamped to the ground plate of the cabinet, using a cable
D For details of the I/O signal specifications, see Section 6.3.

50–pin female connector manufactured by Honda Tsushin
Solder type: A02B–0029–K891 (MR–50LFH)
Crimp type: A02B–0029–K893 (MRP–50F01, MR–50L,
MRP–F112, 50 pins)
20–pin female connector manufactured by Honda Tsushin
Solder type: A02B–0029–K890 (MR–20LFH)
Crimp type: A02B–0029–K892 (MRP–20F01, MR–20L,
MRP–F112, 20 pins)
D The frame of this I/O card is grounded by attaching its metal fixture
to the cabinet.
D On the PCB, a red LED beside the driver element lights once the over
current or overheat detection circuit operates.
Red LED name DO signals
DAL1 Y q + 0.0 to Y q + 0.7
DAL2 Y q + 1.0 to Y q + 1.7
DAL3 Y q + 2.0 to Y q + 2.7
DAL4 Y q + 3.0 to Y q + 3.7
DAL5 Y q + 4.0 to Y q + 4.7
DAL6 Y q + 5.0 to Y q + 5.7
DAL7 Y q + 6.0 to Y q + 6.7
DAL8 Y q + 7.0 to Y q + 7.7
The above red LED and alarm transfer to the Power Mate
are supported by PCBs of version 03B and later.
D If the overheat detection circuit in the output driver detects over
current or overheat (see Section 6.3.2), an alarm is sent to the Power
Mate, resulting in a system error. Closing the jumper bar at CP1 on
this printed–circuit board can keep this alarm from being sent to the
Power Mate. In this case, therefore, a system alarm will not occur. See
Section 6.6.5 for the location of CP1.
