Emerson Ovation 4D33888G01 AC Distribution Panel

The S-series H1 with integrated power provides local LED indicators to assist in trouble shooting:

„ 2 Yellow LED’s: One per port Indicating the port is enabled and communicating with devices.

„ 2 Red LED’s: One per port indicating to health of power supply as well as monitoring voltage or short circuit faults on the physical layer.

„ Fault LED: Indicates internal fault with the H1 card.

„ Power LED: Indicates available LocalBus power.

The Fieldbus I/O Card meets ISA G3 corrosion specifications by using superior electronic components and conformal coating.

One of the most powerful features of FOUNDATION Fieldbus devices is their diagnostic data.

Using AMS Device Manager, you can access all of the necessary information to configure,commission, monitor, 

and troubleshoot all your FOUNDATION Fieldbus smart devices. Improved device diagnostics can lead to increased product quality and minimize unplanned downtime.

Improve the productivity and profitability of your process control system with FOUNDATION Fieldbus.

Product Description

FOUNDATION™ fieldbus I/O is a modular subsystem that communicates digitally with field devices, 

increases your input/output capacity, and gives you access to more information about your process than conventional I/O subsystems. 

It greatly enhances device diagnostics that affect your control strategy and alerts operators to device malfunctions. 

If you want an efficient, economical, and secure process control system, use DeltaV™ FOUNDATION fieldbus I/O.

Maximize smart device capabilities. Increase your quality and throughput by taking advantage of the added diagnostics

of FOUNDATION Fieldbus I/O devices. Field device status is updated continuously using FOUNDATION Fieldbus I/O.

For multi-variable devices, all process variables are available on the single fieldbus at the cost of a single Device Signal Tag.

Redundant H1 cards provide increased availability.

The DeltaV system offers redundant H1 interfaces. The two H1

interfaces are connected with a redundant terminal block to

provide back-up link active schedule (LAS) capability that also

maintains communication with the host system. 

Transfer to the standby card is automatic and requires no special configuration.

Ongoing diagnostics ensure the standby H1 card is available on demand. 

This process requires no user interaction.

Our Business

Emerson’s industry-leading portfolio enables us to identify and confront the challenges of an 

increasingly complex and unpredictable marketplace from a position of strength, 

driving near- and long-term value as a trusted partner for our customers.

The FOUNDATION Fieldbus H1 interface is packaged in a small form factor enclosure and installs on any I/O slot of the S-series horizontal carriers. 

The interface uses a separate terminal block to which the segment wires are connected. 

A single interface is used with the 1 wide terminal block in a simplex installation. 

Two H1 interfaces can be mounted in adjacent slots using the 2-wide redundant terminal block. 

The DeltaV controller recognizes the presence of redundancy and presents both cards as a single pair within the system. 

There is no additional user configuration required to set up the redundant H1 hosts. 

Segment Power is provided using third party Ff power supplies that also provide segment physical layer diagnostics. 

The H1 interface segment wires connect to these power conditions while a separate segment trunk wire connects to the field devices
