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.
