CB150 (HONDA MR–50RMA)
50 male pins with fittings for
fixing the connector covers
NOTE
1 The DI and DO addresses for the basic and expansion
modules run contiguously. These basic and expansion
module DI and DO addresses are allocated to the I/O Link
as a group. For example, when the DI and DO top
addresses are X0004 and Y0000 (m = 4 and n = 0),
respectively, then the addresses are allocated as shown in
the following table.
2 Pins 18 and 50 (+24V) of connector CB150 are used to
apply 24 V externally to a module. Be sure to connect these
pins because the +24 V applied to the module is used
internally.

Basic module X4–X6 Y0–Y1
Expansion module 1 X7–X9 Y2–Y3
Expansion module 2 X10–X12 Y4–Y5
