May 2022
Instruction Manual
D103198X012
NOTICE
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 ranges 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 the related instruction
manual supplements as indicated in Hazardous Area Classifications and Special Instructions for “Safe Use” and
Installation in Hazardous Locations on page 7.
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.
NOTICE
Do not use sealing tape on pneumatic connections. This instrument contains small passages that may become obstructed
by detached sealing tape. Thread sealant paste should be used to seal and lubricate pneumatic threaded connections.
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 one 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.

Mounting
When a transducer is ordered as part of a control valve assembly, the factory mounts the transducer on the actuator
and connects the necessary tubing, then adjusts the transducer as specified on the order. See figures 3 and 4 for
typical mounting configurations.
