TEIP11 · V18312H
Standard signal converter with control-room and field versions. Typically converts 4–20 mA to 0.2–1 bar / 3–15 psi. Direct or reverse action and different supply pressures are available.
Current-to-pressure conversion
ABB I/P converters
An I/P converter is a simple solution for converting 4–20 mA into a standard pneumatic signal without closed-loop valve-position control.
TEIP11-PS · V18311H
Includes a pneumatic power stage for loads or actuators requiring greater pneumatic capacity.
Practical selection
I/P converter or positioner?
| Function | I/P converter | Positioner |
|---|---|---|
| Converts 4–20 mA to pressure | Yes | Yes, internally |
| Reads actual valve position | No | Yes |
| Compensates for friction / process forces | No | Yes |
| Diagnostics / HART | Usually not | Yes, on digital versions |
| Simplicity / pneumatic retrofit | A strong fit | More complex |
Best practice
I/P installation
The output signal alone is not enough: supply pressure must match the specified code and configuration.
Filter and dry the air to protect nozzles and restrictions and maintain signal stability.
Check signal direction before connecting to a valve or conventional positioner.
IP20, aluminium or stainless steel field enclosures and Ex versions have different limits and certifications.
A leak between the I/P and actuator changes actual pressure and dynamic response.
An I/P converter does not know whether the valve has reached the requested position.
Current codes we supportTEIP11 = V18312H; TEIP11-PS = V18311H. The legacy 18311 family is identified through the full code or nameplate to avoid incorrect replacements.

Technical FAQ
I/P converter FAQ
Are TEIP11 and TEIP11-PS the same?
No. TEIP11 V18312H has no power stage; TEIP11-PS V18311H integrates a pneumatic power stage and can drive loads requiring greater air flow directly.
Which signals do they convert?
Typically 4–20 mA or 0–20 mA to 0.2–1 bar / 3–15 psi, with other options depending on configuration.
When is an I/P sufficient, and when is a positioner required?
An I/P is sufficient for a proportional pneumatic signal. For actual valve-position control against friction, process forces and hysteresis, use a positioner.
Are ATEX versions available?
Yes. TEIP11/TEIP11-PS includes intrinsically safe and flameproof configurations depending on enclosure and code.
Why does TEIP11 have so many enclosure options?
It can be mounted in a control room, on rails or blocks, or directly in the field in aluminium or stainless steel enclosures, including Ex versions.
What should be checked during commissioning?
Current input, pneumatic output, supply pressure, direct/reverse action, tubing tightness and air filtration.
