WELCOME
ABOUT BD-DEVNET
Thank you for purchasing a BD-DEVNET. BD-DEVNET allows DeviceNet customers to take
advantage of the world’s leading I/O hardware from Opto 22. The configuringable board,
which can control up to 16 digital I/O points, connects easily with Opto 22’s digital I/O
mounting racks. Software parameters can be set using standard DeviceNet tools (node
address and operaing speed may also be set by switches), allowing the board to
communicate on a DeviceNet network.

ABOUT OPTO 22
Opto 22’s goal to deliver total control to industrial automation customers dates back to
its beginnings in 1974 with the introduction of optically-isolated solid-state relays.
Today, Opto 22 is the number one provider of I/O systems, with more than 80 million
points of I/O working reliably worldwide. After earning a reputation for consistent
innovation and leadership in automation hardware, Opto 22 realized it was time to take a
new approach to control software. In 1988, Opto 22 introduced the first flowchart-based
control programming language. Opto 22 continues to deliver successively more advanced
generations of hardware and software.
All Opto 22 products are manufactured in the U.S. at the company’s headquarters in
Temecula, California, and are sold through a global network of distributors, system
integrators, and OEMs. Sales offices are located throughout the United States. For more
information, contact Opto 22, 43044 Business Park Drive, Temecula, CA 92590-3614.

INTRODUCTION
INTRODUCTION
OVERVIEW
The BD-DEVNET is a DeviceNet-compatible 16-channel digital I/O adapter that allows DeviceNet
customers to integrate Opto 22 digital I/O mounting racks on the popular DeviceNet communication and
power network.
The BD-DEVNETs brain board form-factor and standard 50-pin header connector allows the
digital adapter to plug directly into Opto 22 digital I/O mounting racks similar to Opto 22s other
16-channel digital brain boards (B1, B5, and B100). The BD-DEVNET can be powered either from
the 5V on the I/O rack or from the standard DeviceNet 24 VDC bus power.
Software parameters, set using standard DeviceNet tools, allow the unit to be configured to
meet a wide range of industrial interface requirements. The BD-DEVNETs network node
address and operating speed may be set up using an eight position switch or as software
parameters. Network signals are connected using removable screw terminals, simplifying field
installation. The CAN interface includes on-board circuitry to protect against wiring faults such
as loss of ground and reverse polarity.
