Introducing Discrete Block I/O

In this chapter, you will learn what ac and dc block I/O is, its features, and

how it functions.

Block I/O modules are small, self-contained remote I/O devices complete

with power supply, programmable controller interface, input/output

connections and signal conditioning circuitry.
