ABB I/P converters
ABB TEIP

I/P converters

TEIP11 V18312H and TEIP11-PS V18311H convert 4–20 mA to 0.2–1 bar / 3–15 psi, with field, control-room and Ex versions.

Understanding the control chain

What does each component do?

Control valve

The final element changes flow and therefore the process variable.

Actuator

Converts air or energy into linear or rotary valve movement.

Positioner

Compares setpoint with actual position and adjusts actuator air in a closed loop.

I/P converter

Converts current into pneumatic pressure without actual position feedback.

Pneumatic controller

Measures and controls a variable without electronics, using a standard pneumatic signal.

DCS / PLC

Generates commands and manages logic, interlocks, PID and supervision.

FAQ

Frequently asked questions

What is the difference between a valve, positioner and I/P converter?

The valve physically modulates fluid flow; the positioner closes the loop on actual actuator position; the I/P converter only converts an electrical signal into a pneumatic one.

When is fully pneumatic instrumentation still required?

For legacy installations, plants with pneumatic architectures, environments avoiding local electronics or where continuity with existing instrumentation is the priority.

Does Geyser supply only ABB?

No. Control-valve supply is multibrand. ABB remains an important part of our positioner, pneumatic and I/P portfolio.

Do you supply Kent Taylor spare parts?

Yes. Older ABB/Kent Taylor valves are no longer a current range, but we support spare-parts sourcing, retrofits and multibrand replacement.
