EXAMPLE OF I/O SYSTEM CONSTRUCTION
Recently, the microcomputer shown in
the left has come into use, with a rapid in-
crease in the use of feedback control for
process controllers. As an input/output in-

space saving. Our company’s I/O relays
have been grouped for use with either AC
or DC devices as AC output type, AC in-
put type, DC output type, and DC input.
In addition, the I/O use relay is modular-
ized identically, responding to the various
load types for PC board mounting. Be-
cause combinations can be freely used,
circuit design has been greatly facilitated.
Accordingly, the above diagram of inter-
face PC board mounting is a practical
construction which can be used.
