supply to several locations, better noise immunity is obtained by
having separate power supplies at each physical location where
a rack/brain board unit is installed. The +5 VDC power supply is
connected to the I/O mounting rack beneath the removable brain
board portion of the digital Optomux unit.
to power the analog I/O modules. The amount of power required
depends on the type and number of analog I/O modules that are
plugged into the Optomux unit. See the data sheets for your
modules; power requirements for each module are included in the
module specifications.
supply that can be used for powering a 4–20 mA current loop
using 4–20 mA analog I/O modules. For this type of application,
the +24 volt supply is required in addition to the supplies mentioned
Installation and Wiring
The B1 and B2 brain boards require +5 volts DC (± 0.1 VDC)
Although it is possible to distribute DC from a common power
Analog racks also require +15 VDC and -15 VDC (± 0.25 VDC)
Analog racks also provide terminals for a separate +24 volt

only for the modules. To determine what size power supply is
needed, add the load requirements for each module to determine
total power supply requirements.
Isolated supplies reduce the risk of ground loops in the
communication wiring. Do not connect the power supply’s DC
common to earth ground. Linear power supplies are recommended.
Connecting the Power Supply
“+ 5V” and “GND” on the mounting rack. If the + 5-volt supply is
used by more than one unit or by other devices, make sure the
voltage at each rack is 5 VDC (± 0.1 V).
