DESCRIPTION
Use your Raspberry Pi in the real world!
Available only for a limited time, the Digital I/O for Raspberry Pi Starter
Kit gets you started sensing and switching industrial loads with your
own Raspberry Pi.
The system includes the same field-tested, industrially hardened Opto
22 G4 input/output (I/O) modules used in automation applications
worldwide for nearly 40 years. Just bring your Pi and its power supply,
and you’re ready to begin.

Read and Write with Pi
It’s easy to read and write to Opto 22 I/O points using your favorite Pisupported language—Python, Node-RED, Pi Terminal, Pi Filesystem
GPIO, or others.
Visit developer.opto22.com for code samples and tips for using your Pi
to read and write to Opto 22 I/O modules.
The Starter Kit includes all of the following:
OPTO-P1-40P Digital I/O Carrier Board, including interface cable,
Pi board mounting standoffs, and spare fuse for mounting rack
G4PB8H 8-module mounting rack
G4IAC5 90-140 VAC/VDC input module
G4IDC5MA 10-32 VDC input module with manual/auto Switch
G4OAC5 12-140 VAC output module
G4ODC5 5-60 VDC output module
With the Starter Kit, you can use your Pi to switch industrial-level
electrical loads far beyond the Pi's built-in 3.3 VDC GPIO pins. You can
monitor and control real-world devices like industrial motors, pumps,
and sensors.
And you’ll know that you can count on reliable Opto 22 industrial I/O,
manufactured and supported in the U.S.A. is free,
and most I/O modules are guaranteed for life.
Room to Expand
The Starter Kit gives you plenty of room to expand. You can add up to
4 additional I/O modules on the mounting rack (choose from the list
of compatible G4 modules).
In addition, the Carrier Board’s auxiliary 40-pin GPIO connector lets
other Pi-compatible peripherals access the Pi’s unused pins.

GETTING STARTED
The Starter Kit works with any model Pi with a 40-pin header
connector. Here’s what’s in the box:

Small parts
Interface cable
Carrier Board
G4 I/O modules
G4 mounting rack
1. Snap the Carrier Board onto the G4 mounting rack connector.
2. Carefully open the bag of small parts.
Fuse
Standoffs
Screws
5. Remove an I/O module from its box and carefully install it in
position 0 on the board. Secure it with its integral screw.
3. Use the four screws to secure the Pi to the top of the Carrier Board,
placing a standoff between the Pi and the Board for each screw.
4. Insert one end of the interface cable into your Pi's GPIO
connector. Insert the other end into the Carrier Board’s gray
connector, making sure it locks in place.
6. Install and secure the other 3 modules next to the first one.
Terminal strip for wiring
7. Follow “Field Wiring Diagrams” on page 4 to wire real-world
sensors and devices to the mounting rack.
CAUTION: AC wiring is dangerous and should be done by a qualified
electrician.
For additional wiring information and complete specifications,
see form 2208, the Digital I/O for Raspberry Pi Selection Guide. (This
guide also shows all the other Opto 22 I/O modules you can use
with your Pi.)

8. Plug in your Pi’s power supply. (If you’re using peripherals, see
“Powering Peripherals” on page 3.)
9. Use your favorite Pi-supported programming language to read
and write to the I/O points.
Visit developer.opto22.com for code samples and tips for using
your Pi to read and write to Opto 22 I/O modules.
The mapping diagram at right and the “Mapping Overlay for
Raspberry Pi” on page 3will help you know which pins apply to
each module on the rack.
NOTE: Opto 22 I/O modules use negative true logic; that is, a zero bit
means On and a 1 bit means O
points, remember that 0 is On and 1 is Off.
ff. When reading and writing to I/O
Powering Peripherals
IMPORTANT: If your Pi uses USB-powered peripherals (especially hard
drives or WiFi dongles), do the following:
Connect a 5 V power supply rated 2.5 A to 5 A to the G4 rack’s
power terminals (located underneath the Carrier Board).
Replace the G4 rack’s standard 1 A fuse with the 5 A fuse that
came in the bag of small parts.

Older products
From solid state relays (our first products) to world-famous G4 and
SNAP I/O, to SNAP PAC controllers, Opto 22 products last a long time.
You can count on us to give you the reliability and service you expect.
QUALITY
Founded in 1974, Opto 22 has
established a worldwide reputation for
high-quality products. All are made in
the U.S.A. at our manufacturing facility
in Temecula, California.
Because we test each product twice
before it leaves our factory rather than
testing a sample of each batch, we can
guarantee most solid-state relays and
optically isolated I/O modules for life.
Support is always available on our website, including online training,
how-to videos,
Configuring and troubleshooting I/O and networking is easier with
the EPIC’s integrated high-resolution touchscreen. Authorized users
can see your groov View HMI locally on the touchscreen or on a
monitor connected via the HDMI or USB ports.
groov EPIC Software
