Introduction

The DeltaV™ S-series Mass Connection Solutions provide fast, 

easy and reliable connection from field devices to DeltaV 

simplex and redundant, high density traditional I/O Cards, 

while providing several wiring options. 

The modular design of the Mass Connection Boards further 

helps to lower the overall termination footprint due to flexible 

mounting capabilities.

Ribbon cable connectors will be used to connect the Mass 

Connection Boards easily to the simplex or redundant, high 

density traditional I/O Cards, where loop and termination 

fault diagnostic information are available.

Benefits

Fast, easy way to connect terminals. The DeltaV simplex and 

redundant high density traditional I/O Cards can be easily wired 

to the Mass Connection Boards within seconds. 

No tools are necessary to connect the ribbon cables, so you 

can significantly reduce labor costs by eliminating additional 

cabinet wiring.

Modular design, improves reliability. The modular designed 

Mass Connection Boards are more reliable than other traditional 

solution, by splitting the Signals up, to a max of 16 Signals.

Optimization of space. The DeltaV S-series Mass Connection 

Solutions offer significant space advantages by integrating all 

needed cabinet wiring components on one board.

Significant labor work reduction. No need for cross wiring 

between I/O cards and Mass Connection Boards anymore, due 

to flexible 1:1 ribbon cable based connectivity. 

Significant cost reduction. Since off-the-shelf Ribbon cables 

can be used inside a Cabinet with a max. Length of 3 m, 

significant cost reductions can be achieved. 

In some cases, longer cables are needed for connections 

between two Cabinets. 6m long Standard Round Ribbon Cables 

can be ordered to be used with the Mass Connection Solutions.

Loop Disconnect Features for all Signal Types. For each 

Signal Type, a loop disconnect feature is available on the Mass 

Connection boards. 

On the AI/AO Mass Connection boards, this is realized using a 

specific knife edge disconnect setup with 2mm test holes, in 

this way maintenance or calibration work can be performed 

without disturbing the 4-20 mA loop based Signal.

On the DI/DO Mass Connection boards, this is realized using 

replaceable fuses. In this way, loop power to the field can be 

easily disconnected, during maintenance activities.

Termination Fault Detection. With the DI/DO Mass 

Connection boards, power or cable failures can now be 

detected by DeltaV Diagnostic when used with the new

Plus Cards.

Product Description

AI/AO Plus Mass Connection Board

The AI/AO Plus Mass Connection Board connects to the new 

S-series Plus (simplex or redundant) AI, 16 Channel and AO, 

16 Channel cards by using either two ribbon cables with 24-Pin 

connectors or the 48-Pin special Round Ribbon Cable, which is 

required if the distance is longer than 3m.

Up to 16 Analog, 4-20 mA HART based Field devices can be 

connected to the AI/AO Plus Mass Connection Boards by screw 

terminals. 2- And 4- wire Devices are supported by the 

3- row screw architecture, so you can choose on a Channel 

by Channel basis.

For each Channel, a loop disconnect feature with 2mm test 

holes is implemented. In this way, maintenance or calibration 

work can be performed at any time, without disturbing the 

4-20 mA loop based Signal.

Please refer to the Cross Reference List for your application. 

DI Mass Connection Board (for simplex DI Card)

This DI Mass Connection Solution (set of two boards) connects 

to the existing simplex S-series DI, 32 Channel, 24 VDC, Dry 

Contact cards by using either two ribbon cables with 20-Pin 

connectors or two of the 20-Pin standard Round Ribbon Cable, 

which is required if the distance is longer than 3m.

Up to 16, 24 VDC based discrete input Signals can be connected 

to each of the DI Mass Connection Boards by screw terminals. 

Dry Contact or 24 VDC Isolated Field Signals are supported by 

the 2- row screw architecture.

Yellow LED’s are providing status Indication for each Channel, 

while the replaceable fuses can be used to disconnect loop 

power to the field, during maintenance activities.

Please refer to the Cross Reference List for your application. 

DI Plus Mass Connection Board (for DI Plus Card)

The DI Plus Mass Connection Solution (set of two boards) 

connects to the new redundant S-series Plus DI, 32 Channel, 

24 VDC, Dry Contact cards by using either two ribbon cables 

with 20-Pin connectors or two of the 20-Pin standard Round 

Ribbon Cable, which is required if the distance is longer 

than 3m. 

Up to 16, 24 VDC based discrete input Signals can be 

connected to each of the DI Plus Mass Connection Boards by 

screw terminals. Dry Contact or 24 VDC Isolated Field Signals 

are supported by the 2- row screw architecture.

Yellow LED’s are providing status Indication for each Channel, 

while the replaceable fuses can be used to disconnect loop 

power to the field, during maintenance activities.

A Termination Fault Detection feature is built into each of 

the DI Plus Mass Connection boards which allows the new

redundant S-series Plus DI, 32 Channel, 24 VDC, Dry Contact 

cards to detect power or cable failures on the board. There is a 

jumper on the board to be able to turn this feature off, in case 

rewiring needs to be performed while the process is running. 

The new S-series Plus DI, 32 Channel, 24 VDC, Dry Contact 

card does have two new parameters in the Explorer view, 

one for each cable connection. When these Parameters are 

turned on, DeltaV Diagnostics will mark the status of affected 

Signals accordantly.

Please refer to the Cross Reference List for your application.

DO Plus Mass Connection Board

The DO Plus Mass Connection Solution (set of four boards) 

connects to the existing simplex S-series DO, 32 Channel, 24 

VDC, High-Side cards as well to the new redundant S-series 

Plus DO, 32 Channel, 24 VDC, High-Side cards by using either 

two ribbon cables with 20-Pin connectors or two of the 20-Pin 

standard Round Ribbon Cable, which is required if the distance 

is longer than 3m. Two DO Plus Mass Connection boards 

need to be daisy chained to get to 16 Channels, which can be 

connected back to the card. A short ribbon cable with 20-Pin 

connectors can be used for that purpose too.

Up to 8 Field devices can be connected to each of the DO Plus 

Mass Connection Boards by screw terminals. Either +24 VDC 

high-side relay outputs or voltage free relay contacts can 

be used, pending on the position of the fuse, which can be 

jumpered for this reason.

Yellow LED’s are providing status Indication for each Channel, 

while the replaceable fuses can be used to disconnect loop 

power to the field, during maintenance activities.

A Termination Fault Detection feature is built into each of 

the DO Plus Mass Connection boards which allow the new 

redundant S-series Plus DO, 32 Channel, High-Side cards to 

detect power or cable failures on the board. There is a jumper 

on the board to be able to turn this feature off, in case rewiring 

needs to be performed while the process is running
