Introduction
This section provides a brief overview of the KMD-5831 Programmable Loop
Controller PLC-28 and the KMD-5821 Programmable Loop Controller PLC-16 +
Direct Digital Controllers. Review this material before you attempt to install the
controller.
For clarity we will focus on the KMD-5831 but all installation and operating
instructions apply equally to the KMD-5821.
Illustration 1 shows the major controller components and their locations. The
KMD-5821has fewer inputs and outputs.
Note:
Additional components are located under the blank cover. We will cover these in
detail later in this document.
