The E69F Field Mount Current Pneumatic Signal Converter accepts a standard DC input signal and converts it to a proportional pneumatic output signal for use with other pneumatic instruments or control valves.
and converts it to a proportional pneumatic output signal for use with other pneumatic instruments or control valves.
As indicated by the “CE” marking on the product, it complies with applicable European Union directives.
Compact and easy to install
The small size and compact design of the E69F converter allows for easy connection to electrical and pneumatic interfaces.
It can be easily mounted on a surface, on a valve yoke or on a vertical pipe with a nominal DN 50 or 2.
Minimal influence on ambient atmospheric conditions
The design of the corona motor in the E69F converter allows a large clearance between the coil and the housing.
Normal atmospheric variations may cause corrosion and dust particles, but will not impede www.abb-drive.com the operation of the mechanism as would be the case with voice coil type instruments.
Wide range of applications
Selectable input and output signals, different input ranges, and direct or reverse action make this converter easily adaptable to a wide variety of applications.
The choice of output signals makes the converter particularly suitable for valve applications.

Air Supply Pressure Effect
Zero shift due to changes in air supply pressure is less than 0.04% per kPa (0.25% per psi).
Ambient Temperature Effects
Over an operating temperature range of 0 to 60°C (32 to 140°F), a change in ambient temperature of 28°C (50°F) will result in a zero and range shift of ±1.0% or less.
Tilt Effect
A 5-degree change in inclination from the vertical results in a maximum zero shift of 0.25% of range. This error can be eliminated by calibrating the instrument at the intended mounting position.
Shock Effect
The maximum zero offset is 0.5% of the range for a 300 m/s2 (30 “g”) shock test on a feedback support frame.
