Wiring
Input/Output terminals are arranged on the rear panel of the CX2000 as shown in the
figure below. The figure shows the case when option terminals are specified on the
model with 6 internal control loops and 20 measurement channels (CX2620). For the
wiring procedure of the control/measurement input/output, see chapter 2, “Installation
and Wiring” in the CX2000 User’s Manual (IM 04L31A01-01E) or the CX2000 Installation
and Connection Guide (IM 04L31A01-71E).
For a description on the connection of
communication interfaces such as the serial or Ethernet interface, see the CX2000
Communication Interface User’s Manual (IM 04L31A01-17E)
