The Rail-Mounted Universal Input/Output module is designed to mount the Series C Universal
Input/Output module vertically on a 35 mm TS-35 DIN (Deutsches Institut für Normung) rail. The
entire mounting arrangement is used in non-standard Honeywell cabinets, and wall mount
standalone scenarios.
ATTENTION
l You should not mount the rail-mounted UIO module horizontally on a DIN rail.
l The mounting of Input/Output Termination Assembly (IOTA) and power supply for
rail-mounted UIO module is identical to the mounting of IOTA and power supply for
Series C I/O modules.
The rail-mounted UIO has the following categories.
l Mechanical – This category is used for holding the IOTAs/IOMs that can be mounted outside
the standard Honeywell cabinet with provision for routing the system cables.
l Electrical – This category is used for providing an interface to connect ground and power from
external power supply to the IOTA screw terminals in non-standard Honeywell cabinets where
bus bars are not present. The interface has Printed Wiring Assembly (PWA), which also
includes Reverse polarity, Electrostatic discharge (ESD) and Surge protections complying with
CE standards.
8.1 Benefits
The following are the benefits of rail-mounted UIO module.
l Space consumption is less.
l Cost-effective since there is no investment required for cabinets to mount the module.
l Relocation of components is simple and easy.
