Description

FOXBORO E69F-BI2
‘Introduction
The E69F Current-to-Pneumatic Signal Converter is a field-mounted instrument that transforms
a dc milliampere input signal to a proportional pneumatic output signal. This output signal can
be used either to operate such pneumatic devices as dampers, and valve actuators, and so forth, or
as the input to various pneumatic instruments.
The E69P Current-to-Pneumatic Valve Positioner is a yoke-mounted instrument that converts a
dc milliampere input signal to a pneumatic output. The output is calibrated for a specific valve
stroke rather than for a pneumatic output signal. The positioner delivers all the air required,
limited to its supply pressure, to reposition the valve stem to satisfy a given input.
Electrical Rating
The electrical rating is printed on the data plate. For special requirements see Table 1.
NOTE
These instruments have been designed to meet the electrical safety description listed
in Table 1. For detailed information or status of testing laboratory
approvals/certifications, contact Invensys Foxboro.
Operating Temperature Limits
The operating temperature limits of the electronics are -40°C and +80°C (-40°F and +180°F).
Ensure that the instrument is operated within this range.
Origin Code
The origin code identifies the area of manufacture and the year and week of manufacture. See the
example shown in Figure 1. In the example, 2A means the product was manufactured in the
Measurement and Instrument Division, 04 identifies the year of manufacture as 2004, and 12,
the week of manufacture in that year.
Hazardous Location Rating
The hazardous location code is printed on the data plate as the CERT. SPEC. See the example
shown in Figure 1. See Table 1 to identify this code. The type of protection is also marked on the
agency plate.
Input Current
The input current is printed on the data plate. Ensure that a 4-20 mA signal (Input Signal
Code I) is used with instruments certified as intrinsically safe.
