Uni-I/O™ Wide
Modules
Uni-I/O™ Wide is a family of Input/Output modules that are compatible with the
UniStream™ control platform. Wide Modules are 1.5 times as wide as Uni-I/O™ modules,
and comprise more I/O points in less space.
This guide provides basic installation information for UIS-WCB1 Uni-I/O™ module.
Technical specifications may be downloaded from the Unitronics website.
The UniStream™ platform
comprises CPU controllers, HMI
panels, and local I/O modules
that snap together to form an
all-in-one Programmable Logic
Controller (PLC).
Install Uni-I/O™ modules:
 Onto the back of any
UniStream™ HMI Panel
comprising a CPU-for-Panel.
 Onto a DIN-rail, using a
Local Expansion Kit.
The maximum number of Uni-I/O™ Wide modules that can be connected to a single CPU
controller is limited. For details, please refer to the specification sheets of the
UniStream™ CPU or any of the relevant Local Expansion Kits.
Before You Begin
Before installing the device, the installer must:
 Read and understand this document.
 Verify the Kit Contents.
Installation option requirements
If you are installing a Uni-I/O™ module onto:
 A UniStream™ HMI Panel; the Panel must comprise a CPU-for-Panel, installed according
to the CPU-for-Panel installation guide.
 A DIN-rail; you must use a Local Expansion Kit, available by separate order, to integrate
the Uni-I/O™ modules on the DIN-rail into a UniStream™ control system.
