2.4 What is Universal Input/Output (UIO) Module?
With R410, an Universal Input/Output (UIO) module is introduced that enables you to configure the input/
output channels within a single IOM. The UIO module supports 32 channels. Each channel can independently
be configured as one of the following types.
• Analog Input channel (0-20mA or 4-20mA)
• Analog Output channel (4-20mA)
• Digital Input channel (with or without broke-wire detection)
• Digital Output channel (with or without broke-wire detection)
The UIO channels and device blocks are compatible with existing Series C AI, AO, DI, and DO channels and
blocks. In addition, each analog channel in the UIO module can be configured to support HART input/output
functionality.
2.4.1 Features of UIO
The following list illustrates the key features of the UIO module.


8.3 Single Mode FOE for rail-mounted UIO

One SMFOE is used for connecting to a matrix of 3X3 rail-mounted UIO network or lower. Refer to the
figures in the section “System wiring” on page 284 for illustration.

Universal I/O
EDI Distributor Control Interface Wiring and Setup Instructions
The UIO module uses low voltage input and outputs but high voltage precautions may be necessary if this module is located in a cabinet containing other electrical equipment.
The Universal I/O, or UIO for short, is a microprocessor based interface module designed to allow user devices, like PLCs, computers and custom control panels, to control EDI distributors. It also allows EDI controls to operate externaldevices, for example alarms, motor starters, relays and solenoids,. With the UIO the user can monitor and operate one or many distributors or setup electricalinterlocks depending on spout position.The UIO is a cost effective, DIN rail mounted multi-function module. It can beplaced far from the EDI control unit, usually inside a custom control panel, along side a PLC, MCC or at a remote operator station. It can then be field configured to operate in several different modes depending on the needs of the user.
A standard UIO kit consists of:
•UIO module with the necessary relays installed
•Wall mounted power supply
•25’ communication cable
•One UCOM adapter card for installation on the EDI control.
•RS-232 ribbon cable 5’ long
