Introduction

Scope of Manual

This instruction manual provides installation, operation, maintenance, and parts ordering information for the Fisher
i2P‐100 transducer (see figure 1).

Refer to separate manuals for instructions covering equipment used with the transducer.

Do not install, operate, or maintain an i2P-100 electro‐pneumatic transducer without being fully trained and qualified
in valve, actuator, and accessory installation, operation and maintenance. To avoid personal injury or property

damage it is important to carefully read, understand, and follow all of the contents of this manual, including all safety
cautions and warnings. If you have any questions about these instructions, contact your Emerson Process

Management sales office.

Instruction Manual

D103198X012

CAUTION

Dropping or rough handling of the transducer can cause damage to the converter module resulting in a shifted output or a
minimum output.

Description

The transducer receives a 4‐20 mA DC input signal and transmits a proportional user field‐configurable pneumatic
output pressure to a final control element. The pneumatic output range are typically 0.2 to 1.0 bar (3 to 15 psig), 0.4
to 2.0 bar (6 to 30 psig), and 0.14 to 2.3 bar (2 to 33 psi). A typical application is in electronic control loops where the
final control element is a control valve assembly that is pneumatically operated. The input signal and output pressure
range of the transducer is indicated on the nameplate, attached to the housing.

Specifications

Specifications for the i2P‐100 transducer are listed in table 1.

WARNING

This product is intended for a specific current range, temperature range and other application specifications. Applying
different current, temperature and other service conditions could result in malfunction of the product, property damage or
personal injury.

Installation

The i2P‐100 transducer has been designed and approved for use with either air or natural gas as the supply medium. If
using natural gas as the pneumatic supply medium, natural gas will be used in the pneumatic output connections of
the transducer to any connected equipment. In normal operation the unit will vent the supply medium into the
surrounding atmosphere unless it is remotely vented. When using natural gas as the supply medium, in a
non‐hazardous location in a confined area, remote venting of the unit is required. Failure to do so could result in
personal injury, property damage, and area re‐classification. For hazardous locations remote venting of the unit may
be required, depending upon the area classification, and as specified by the requirements of local, regional, and
federal codes, rules and regulations. Failure to do so when necessary could result in personal injury, property damage,
and area re‐classification.

Additional information for installation and safe use in hazardous locations can be found in Hazardous Area
Classifications and Special Instructions for “Safe Use” and Installation in Hazardous Locations.

WARNING

To avoid personal injury or property damage from the sudden release of pressure, air, or natural gas:

D Always wear protective clothing, gloves, and eyewear when performing any installation operations.

D If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section of this

instruction manual.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

WARNING

This unit vents the supply medium into the surrounding atmosphere. When installing this unit in a non‐hazardous
(non‐classified) location in a confined area, with natural gas as the supply medium, you must remotely vent this unit to a
safe location. Failure to do so could result in personal injury or property damage from fire or explosion, and area
re‐classification.

When installing this unit in a hazardous (classified) location remote venting of the unit may be required, depending upon
the area classification, and as specified by the requirements of local, regional, and federal codes, rules and regulations.
Failure to do so when necessary could result in personal injury or property damage from fire or explosion, and area
re‐classification.

Vent line piping should comply with local and regional codes and should be as short as possible with adequate inside
diameter and few bends to reduce case pressure buildup.

When received from the factory, the set screws (key 8), which provide a locking feature for the housing caps (key 2),
are backed off approximately 1 turn. When using the i2P‐100 transducer in explosive atmospheres these set screws
must be fully engaged.

WARNING

When using this unit in explosive atmospheres, the set screws (key 8) must be fully engaged to lock/secure the housing
caps. Failure to fully engage these set screws could result in unauthorized opening of the unit, which may result in personal
injury or property damage caused by fire or explosion.

Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installation in Hazardous Locations

Certain nameplates may carry more than one approval, and each approval may have unique installation/wiring
requirements and/or conditions of “safe use”. These special instructions for “safe use” are in addition to, and may
override, the standard installation procedures. Special instructions are listed by approval.

Note

This information supplements the nameplate markings affixed to the product.

Always refer to the nameplate itself to identify the appropriate certification.

WARNING

Failure to follow these conditions of “safe use” could result in personal injury or property damage from fire or explosion,
and area re‐classification.

ATEX

All Approvals

All ATEX approved units come with a combined nameplate which carries multiple approvals (intrinsic safety and dust,
flameproof and dust, and Type n and dust), as shown in figure 18. During installation, only one type of protection
method is allowed. The unit shall be marked by the end-user as to which protection method it was installed as and
shall not be changed or utilized in any other manner than was originally marked by the end‐user.

WARNING

For ATEX approvals only, end‐user must select and mark only one protection method upon installation. Once marked it
shall not be changed. Failure to follow these instructions will jeopardize the explosion safety of the transducer, and may
result in personal injury or property damage.
