Preface

This manual describes how to cable, wire, program, and use ERB-24
relay output boards with digital I/O boards, such as the PIO-12.

This guide serves data acquisition system designers, engineers,
technicians, programmers, scientists, and other users responsible for
setting up, cabling, wiring, and writing programs that access the
functionality of the ERB-24 board. This guide assumes that you are
familiar with data acquisition and programming principles and with your
particular application.

The ERB-24 User’s Guide is organized as follows:

● Chapter 1 briefly describes the features, applications, and accessories

supported by the ERB-24.

● Chapter 2 describes the features of the ERB-24 in more detail and

provides a block diagram of the board.

● Chapter 3 describes how to unpack and set up the ERB-24 board.

● Chapter 4 describes how to attach the ERB-24 to digital I/O boards.

● Chapter 5 provides an example of accessing the functionality of an

ERB-24 board using a PIO-12 board and the BASIC programming
language.

● Chapter 6 provides troubleshooting information and information on

how to obtain technical support and repairs for the ERB-24.

● Appendix A lists the specifications for the ERB-24.

● Appendix B lists the connector pin assignments for the ERB-24.

An index completes this guide.
