Install Your Adapter
Chapter Objectives This chapter describes the procedures for installing your adapter,
including how to:
• determine power requirements
• set the network address switches
• install the ControlNet adapter
• wire the ControlNet adapter
• connect programming terminals to the network via the NAP
• install the I/O modules
• install a replacement adapter to an existing system
Determine Power
Requirements The 1734-ACNR adapter requires a typical 24V dc power supply with a
maximum of 10.2 watts of power @ 28.8 volts. It provides 5 watts @ 5
volts for the POINTBus and dissipates 5 watts @ 28.8 volts.
The ControlNet adapter provides a maximum backplane output
current of 1.0A. See the Specifications section of this manual for:
• backplane current consumption for each POINT I/O catalog
number
• current consumption for each of the POINT I/O modules
connected to the 1734 adapter
Extend backplane current beyond 1.0A with a 1734-EP24DC
Backplane Extension Power Supply.
• Use a 1734-EP24DC power supply to supply up to an additional
1.3A of backplane current.
• Use multiple 1734-EP24DC power supplies to reach the
maximum limit of 63 base modules if 25 or fewer of these
modules are analog.
