Input Power
Required input power is regulated 24 VDC
which is supplied by the mother board of the
rack which contains the Node Adapter. An on
board dc-dc converter makes 5 VDC for the
modules logic level circuits. In the 74847-00
Mother Board, connect the 24 VDC supply to
TB1-4 (+) and TB1-3 (-).
Remote I/O Remote I/O Remote I/O Remote I/O Remote I/O
The connection of the Allen-Bradley Remote I/O
(RIO) is made to the Digital/Analog Interface (DAIF)
Board. This is plugged into the Node Adapter
connector at the rear
rear
rear rear rear of the mother board. The
RIO cable wires are connected to J1 on the DAIF
as shown in Figure 1. The RIO cable may be
“daisy-chained” from one node to another per
Allen-Bradley installation specifications. Where a
termination resistor is specified, usually the last
termination point in a chain, the resistor R1 on the
DAIF board may be connected by placing switch
SW1 to the “TERM” position. This connects the 82
Ohm resistor across blue and clear, appropriate
for 230 k baud rate. If the RIO is configured for
another baud rate, place SW1 in the “OPEN”
position, and connect the appropriate resistor
directly across J1 “BLU” and “CLR”.

The DAIF board is used with the Digital Node
Adapter. It is configured for each application by
positioning jumpers E1 and E2. Figure 2b
shows the correct jumper position for Digital
Node Adapter communication to the FloTronics
Atomizer Fiber Optic Speed Control Module.
Figure 2a shows the correct jumper position for
Digital Node Adapter communication to the
FloTronics Digital Air Control Module.

The Digital Node Adapter communicates to five
FloTronics Digital or Atomizer Modules via its own
mother board. It can communicate to an additional
mother board with modules (slave half-rack) by
connecting the Digital/Analog cable (DACAB) from
J2 on the DAIF board to J1 on the slave half-rack
mother board.

The Digital Node Adapter must be set for the
appropriate RIO address. The rack address
and starting quarter are set by switch SW2 as
shown in Figure 3. The Operating Mode, Last
State, Baud Rate and Rack Size are set by
positions 1-5 on switch SW1 as shown in Figure
3.
