Power the Loop: streamline maintenance productivity; eliminate the need for

specialized tools (i.e. power supply, loop resistor, ammeter).

Advanced Diagnostics: quickly resolve device configuration issues;

diagnose 4-20mA loops; configure and test control valves inline.

Performance, Speed and Design: Noticeably faster response times,

higher volume load of calculations, and a drastically improved,

intuitive user experience.

NIST Traceability: The new and improved Device Configuration

Plus Module has been redesigned with unmatched mA current accuracy

and calibrated according to traceable, accredited standards as per

the National Institute of Standards and Technology (NIST).

Bluetooth® Connectivity: The next-gen AMS Trex has been

re-engineered with embedded Bluetooth technology, improving maintenance

productivity and safety with seamless integration with Bluetooth devices.

Rugged and Intrinsically Safe Design: Built to withstand harsh

industrial environments; protected against moisture, extreme

temperatures, and physical shocks, meeting global Intrinsic Safety standards.

Field Device Integrity: Ensure online and offline device configurations

are captured and sync’d with AMS Device Manager software.

Product Description

The S-series IO subsystem has been redesigned with a focus

on fast assembly and simplified power connections. The system

uses only 24V DC bulk power supplies. All power is connected

to system carriers. Bus connectors have been upgraded to

support additional 12V DC power to the IO cards, allowing

additional power carriers to be inserted anywhere along

the bus.

Carriers mount to standard t-type DIN rail with latches that

require no tools for quick installation. The latches can be

released using a blade screw driver. Simply snap the carrier

to the rail and slide adjacent carriers together to engage the

bus connector.

The I/O carrier supports 8 IO modules. Each card can be

connected to an internal 24V DC bus using the Power Buss

Plugs, or it can be individually powered by using the

Power Terminal Plugs. The internal 24V DC bus is divided into

primary and secondary power, with primary power distributed

to odd numbered slots and redundant power distributed to

even numbered slots using the Power Buss Plugs.

Integrated power distribution. Controller and I/O interface

power distribution is integrated into the carriers to reduce and

simplify power and grounding. I/O Carriers have an integrated

shield ground bar to isolate and drain field noise away from

system power. They also provide an integrated redundant 24V

DC bussed field power distribution to reduce installation wiring

and provide fused, isolated power to each I/O interface, using

Power Buss Plugs. Alternatively, the I/O carriers can be ordered

with Power Terminal Plugs to bring dedicated power to each

card, which can be either 24V DC or 120/230V AC. Power Buss

Plugs and Power Terminal Plugs can be mixed on one

I/O Carrier.

A single Power Terminal Plug will come with any 120V AC DI

or 120/230V AC DO card.

Snap In Assembly. All components snap into place without the

use of special tools. The design supports and “easy on” design

to speed up installation and reduce maintenance turnaround.

Carriers snap onto T-DIN Rails. All interfaces and system power

supplies snap into place, eliminating retention screws.

Benefits

Modular design allows flexible installation. A T- type DIN rail

is all you need to mount the power/controller carrier into place.

Snap the I/O interface carriers to the rail and slide to connect

it to the carrier on the left. Add as many carriers as needed,

or use extender cables to move to a new rail. The DeltaV

system’s modular design approach allows you to add I/O

carriers as you need them.

Allows you to expand online. Additional 8-wide carriers may

be added online as desired. Bus extenders provide dual cabling

for robustness, allowing up to 8 I/O carriers for a total of 64

simplex cards or 32 redundant cards.
