SYSTEM 50 RACKS OVERVIEW
I/O Racks
I/O racks are passive backplanes into which
I/O modules can be installed and removed. I/O
racks connect one of the “logic side” terminals
from each module to an associated pin on the
logic side connector for interface to the controller.
I/O bases have an integral processor and dual
port memory chip. The I/O handles scanning
and storage of the I/O information which can be
accessed over the bases address/databus.
Up to 8 racks can be stacked along a DIN rail.
Standard Mounting Racks
Mounting racks provide a convenient method
of connecting to I/O modules. Most racks have
the option of a card edge or header connector
for the logic signals. Field wires are connected
to open or closed terminal blocks.
The modules are plugged into receptacle cups
or connectors and are held in place by hold
down screws, bars or clips. An LED indicates
the status of each digital module. A five amp
replaceable fuse protects the outputs from
short circuits.

I/O Modules
G5 Mounting Racks
G5 mounting racks are designed to
accommodate G5 modules, which incorporate
a status LED in the module. The G5 output
modules also have an integral fuse. This
eliminates the need for module fuses and LED
status indicators on the rack. The G5 modules
are slightly thinner than the standard modules.
When used with the MicroDAC or Microlon
controllers, analog and digital I/O modules can
be intermixed on the same G5 rack.
Miniature-Sized Racks
Our mini racks are much smaller than the
industry standard racks. In addition to saving
precious panel space, mini racks save
installation time by replacing the individual
module screws with a single hold down bar
which is installed with two thumb screws.
UL Recognition/CSA Certification
Those I/O racks indicated as UL and CSA
certified are listed in UL file E94540 and CSA
file LR38763.

Replacement Fuses
All I/O locations on standard and mini I/O
racks are fused with five amp Littelfuse 251-
005 or Bussman GFA5 fuses. Logic supply on
24 and 32 position standard and mini I/O racks
are fused with one amp Littelfuse 251-001 or
Bussman GFA1 fuses. Logic supply on 16, 24
and 32 position G5 I/O racks are fused with
5 x20mm glass fuses rated one amp or five
amps.
Custom I/O Racks and
Termination Assemblies
For applications where our standard I/O racks
do not fit your application, we offer custom I/
O racks and termination assemblies. We have
provided custom I/O racks with the following
features:
• Special control logic connectors
• DIN rail mounting
• Depluggable terminal strips
• Options for sinking and/or sourcing of field
• 19” Rack for mounting options
• Signal conditioning and transient protection
Our application engineers are ready to help
you design your I/O termination assembly. If
you have a unique application, give us a try.
I/O Module and Fuse Sockets
We recommend customers designing their
own mini, standard or G5 I/O racks use Mill-
Max part number 0355-0-15-01-02-01-10-0
sockets or equivalent for the I/O module leads
and Mill-Max part number 0660-0-15-01-20-
02-10-0 or equivalent for Littelfuse pico fuse
leads. Custom OpenLine
use Crane connectors for the input and for the
output.
Logic Supply
To power an I/O rack, connect a power supply
to the 2 position logic supply terminal block,
taking care that the polarity is correct.
Alternately, the I/O rack may be powered
through the 50-pin connector. Pin #49 on all
other racks is +Vcc. Installation of a jumper or
fuse may be necessary on the I/O rack to
complete this connection. See details on the
following pages.
