Wiring
The backplane on the mounting rack establishes the electrical connection between all modules.
Make the following additional wiring connections:
•
The PS 951 power supply module to the power line
•
The sensors and actuators to the digital or analog modules. Connect the sensors and actuators
to a front connector that plugs into the contact pins on the front of each module. You can
connect the signal lines to the front connector before or after you plug it into the module.
The connection diagram of each module is on the inside of the front door. Perforated label
strips are included with each input and output module. Use these strips to note the addresses
of the individual channels on the module. Slip the strips along with their protective trans-
parent covers into the guides on the front door.
Chapter 10 "Analog Value Processing" describes how transducers are connected up to analog
input modules and the feedback modules of the analog output modules.
Sections 3.3.1 through 3.3.6 explain how to connect individual modules.
Please consult the appropriate operator's guide or manual for information on wiring the intelli-
gent input/output modules and communications processors.
