Introduction
Scope of Manual
This instruction manual provides installation, operation, maintenance, and parts ordering information for the Type i2P-100 transducer (see figure 1). Refer to separate manuals for instructions covering equipment used with the transducer.
No person may install, operate or maintain a Type i2P-100 electro-pneumatic transducer without first D being fully trained and qualified in valve, actuator and accessory installation, operation and maintenance, and D carefully reading and understanding the contents of this manual. If you have any questions about these instructions, contact your Fisher sales office.

Figure 1. Type i2P-100 Electro-Pneumatic Transducer
Description
The transducer, shown in figure 3, receives a 4 to 20 milliampere 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) and 0.4 to 2.0 bar (6 to 30 psig). 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.
CAUTION
Dropping or rough handling of the transducer can cause damage to the converter module resulting in a shifted output or a minimum output.

Installation
The i2P-100 transducer has been designed and approved for use with either air or natural gas as the supply medium. 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, 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.
WARNING
To avoid personal injury or property damage from the sudden release of pressure:
D Always wear protective clothing
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 location 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 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.
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 figure 3 and 4 for typical mounting configurations.
Transducers also can be ordered separately for mounting on a control valve assembly already in service, or for mounting on a 2-inch diameter pipestand, or a flat surface. The transducer may be ordered either with or without mounting parts.
Mounting parts include a mounting plate and bolts and, if ordered for pipestand mounting, a pipe clamp. Tubing is not included if the transducer is not factory mounted. Use 0.375 inch diameter tubing for all input and output connections. The length of tubing
