EXAMPLE OF I/O SYSTEM CONSTRUCTION Recently, the microcomputer shown in
the left has come into use, with a rapid
increase in the use of feedback control
for process controllers. As an input/out-
put interface relay, it represents a fast
responding interface with long life, noise-
less, PC board mounting facility, making
circuit design and manufacture simple,
and providing amplification of mainte-
nance with space saving. Our company’s
I/O relays have been grouped for use
with either AC or DC devices as AC out-
put type, AC input type, DC output type,
and DC input. In addition, the I/O use
relay is modularized identically, respond-
ing to the various load types for PC
board mounting. Because combinations
can be freely used, circuit design has
been greatly facilitated. Accordingly, the
above diagram of interface PC board
mounting is a practical construction
which can be used.
TYPICAL APPLICATIONS
1. Optimum for minicomputer and micro-
computer use, and for feed back control
process control systems.
Robot, NC machine, Automatic
Assembling machine. 2. Programmable controllers controls for
motors, solenoids and solenoid valves.
