HoneywellEXPERION PKSSeries C I/O User's Guide EPDOC-X126-en-A November 2019

Universal I/Os. To enable mounting in the existing cabinets, new IOTAs are designed for the C300

Controller, Control Firewall, and the Universal I/O module such that it can fit into the space of the

CB and EC modules. However, the existing TCBxx terminal panel, and the field wiring to the TCBs

are retained. Note that different IOTAs are required for the UIO and UIO-2 modules. Either IOTA

will screw onto the back panel.

The introduction of the UHIO hardware allows customers to migrate their Hiway-based control

system to the FTE-based Experion Series C control system.

The following figure is an example of CB/EC rack that is replaced with the Experion Series C

controllers and Universal I/Os.

In these figures, the following components are shown.

l Control Firewall

l C300 Controller

l Universal I/Os

2.6.1 Mapping the CB/EC racks with UHIO components

The following figure illustrates how to map the CB/EC with the UHIO components.

ATTENTION

Note that you can increase the number of input/outputs by adding the Universal

Input/Output (UIO) modules.

2.6.2 Features of UHIO

The key features of the UHIO are:

l Supports both redundant and non-redundant configuration for C300 Controller, UIO module,

and CF9.

l Supports interchangeability of Series C components.

l Minimizes the effort for rewiring.

The UHIO also supports the following features.

l Provides mechanical connection to the TDC 2000 cabinet Backplane.

l Supports cabinet ground connections through the IOTA mounting screws.

l Provides electrical-mechanical connection to the IOM.

l Provides electrical-mechanical connection to the redundant IOL cable pair.

l Supports 24V fused electrical connections to the IOM(s) - Series C 24V and COM power supply.

l Supports a signal common ground.

l Supports precision resistors for measuring analog inputs

l Supports connection for up to 24 IO channels on the existing TCBs.

l Supports connection for up to 8 additional IO channels at a location.

l Supports manual reset input(s) for restarting a stopped UIO module.

l Supports voltage or current inputs.

l Supports hot-insertion of C300, CF9, and UIO modules.

2.6.3 UHIO hardware

The UHIO uses the following Series C IO components.

l Plug-in modules such as C300, CF9, and UIO.

l FTE network communications between the controller and Experion Station.

l I/O Link between the controller and all I/O modules.

l Series C cabinet power supply.

l Experion Station and Control Builder as operator and engineering interfaces.

ATTENTION

You cannot differentiate the appearance of the UHIO components from other Series C

components in the Control Builder or the Station though the UHIO components are

horizontally-oriented.

2.6.4 Differences between the Series C IOTA and the UHIO IOTA

The following table lists the differences between the Series C IOTA and the UHIO IOTA.

Series C IOTA UHIO IOTA

C300, CF9, and the UIO IOTA is mounted on

the Series C cabinet.

New IOTA developed for C300/CF9 IOTA and UHIO

cannot be mounted on the Series C CCA’s. It can be

mounted in a TDC 2000 basic cabinet (not a Series C

cabinet) or in a PMIO cabinet using a special

mounting bracket.

Series C UIO IOTA does not interface UIO

module to Basic Controller Terminal Panels

(TCBxx). Instead, Series C UIO IOTA is

designed to directly interface with the field

sensors/actuators.

UHIO IOTA is designed to interface the UIO module

to the Basic Controller Terminal Panels (TCBxx).

Series C IOTA is vertically mounted on the

cabinet.

UHIO IOTA is horizontally mounted on the cabinet.

ATTENTION

Series C Hazardous Certifications are not applicable to the UHIO components.

For more information about the C300/CF9/UHIO IOTA, see Series C Universal Horizontal

Input/Output (UHIO) components.

About UHIO certification

General Purpose Certification

The UHIO’s CSA General Purpose certification is applicable within Data Hiway (TDC 2000) cabinets

with the Series C Power supply SPS5792-142935 (HPN 51454517-100). If any modifications have

occurred since first installation, the UHIO’s CSA General Purpose certification is voided and it is

the responsibility of the end user to ensure they are still conforming to all applicable agency rules
