EZ I/O

≡

Description

Octagon EZ I/O digital I/O lines can be used to sense switch closures,
turn on lamps and LEDs, and interface with other devices that have TTL
input or output such as printers and scales. The EZ I/O drives the
Octagon MPB series opto-isolation module racks directly, controlling AC
and DC loads to 240V at 3A. Figure 11-1 shows typical EZ I/O configura-
tions. The EZ I/O port at J11 has the following features:

n

The EZ I/O chip has 24 I/O lines, grouped into 3 ports of 8 bits

n

Each bit is programmable as either 5V input or 5V output

n

Read back state of each pin

n

Easy-to-program

n

Sink and source 15 mA
