NovaTech 8000 Series I/O Components
Modules
I/O modules transfer signals to and from field instru-
ments. Input modules receive signals from transmit-
ters and sensors and convert them into a digital form
for presentation to the EBIM. Output modules receive
commands from the EBIM and transfer them to actua-
tors. A wide range of modules is available, including
types for low-level instrumentation, AC circuits, and
intrinsically safe signals. I/O modules typically have 4,
8, or 16 field channels.
Carriers
Carriers allow the 8000 Series I/O to mount onto a flat
panel or T- or G-section DIN rail. They support and in-
terconnect the EBIM, power supplies, I/O modules and
field terminals, and carry the address, data and power
lines of the internal Railbus. They provide termination
points for the LAN and field wiring cable screens and
can also distribute bussed field power to the I/O mod-
ules. I/O module carriers support eight I/O modules.
Field Terminals
Field terminals provide the interface between the
I/O modules and the field wiring. They include fusing
and loop disconnect as options. A mechanical keying
system prevents an I/O module from being connected
to the wrong type of field terminal. Field terminals
mount onto the module carrier, one to each I/O
module. They are clamped firmly by the I/O module
to form an electrical and mechanical assembly of high
integrity. They may be replaced in service without
removing carriers or disturbing the operation of other
modules.
Power Supplies
8000 Series I/O power supplies accept locally available
unregulated power and provide a regulated supply
for the EBIM and I/O modules. Supply redundancy is
supported. The system power supply at an 8000 Series
node converts the local DC supply to power the node,
and can also provide field power for I/O modules with
low-level field circuits. Where heavy-current or AC
mains circuits are handled by the I/O modules, the
8000 Series method for distributing field power avoids
complex wiring at the field terminal and minimizes the
backplane/carrier wiring.
