ABB V18311H-382210100 I/P Signal Converter | TEIP11-PS with Power Stage Specs

ABB V18311H-382210100 I/P converter specifications. 4-20mA to 3-15psi, ATEX certified, IP65 aluminum housing, with power stage. For hazardous area applications.

ABB V18311H-382210100 I/P Signal Converter

The ABB V18311H-382210100 is a TEIP11-PS series current-to-pneumatic (I/P) signal converter with integrated power stage, designed for use in hazardous areas. It converts a 4-20mA electrical input signal into a proportional 3-15psi pneumatic output pressure and is ATEX certified for Zone 1/2 applications.

Key Features

• ATEX Certification:​ Approved for use in hazardous areas (Zone 1/2, Ex ia IIC T6/T4 Gb).

• Integrated Power Stage:​ Built-in power amplification for driving larger actuators.

• Robust Construction:​ Aluminum field housing with IP65 protection rating.

• HART Communication:​ 4-20mA two-wire input with HART protocol for configuration and diagnostics.

• Direct Action:​ Linear conversion characteristic for precise control.

Technical Specifications

Model Number Decoding (V18311H-382210100)

• V18311H:​ Series identifier for TEIP11-PS I/P converters

• 3:​ Explosion protection (3 = ATEX II 2 G Ex ia IIC T6/T4 Gb)

• 8:​ Housing type (8 = aluminum field housing, IP65)

• 2:​ Input signal (2 = 4-20mA)

• 2:​ Output signal (2 = 3-15 psi)

• 10:​ Characteristic (10 = direct action)

• 1:​ Ambient temperature (1 = -40°C to +85°C)

• 00:​ Version/color (00 = standard)

Key Differences from V18311H-182210100

The primary difference is the explosion protection certification:

• V18311H-382210100:​ ATEX certified (3 in position 2) for hazardous areas

• V18311H-182210100:​ Standard version without explosion protection (1 in position 2)

All other technical specifications (input/output signals, housing, accuracy, etc.) remain identical between these two variants.

Typical Applications

• Control valve positioners in petrochemical and chemical plants

• Pneumatic actuator control in hazardous areas (Zone 1/2)

• Process control systems requiring ATEX certification

• Oil and gas production facilities

• Pharmaceutical and food processing (where explosion protection is required)

Important Selection & Installation Notes

1. Hazardous Area Classification:​ This model is certified for Zone 1/2 hazardous areas. Verify that your application's area classification matches the certification.

2. Power Stage:​ The integrated power stage provides higher air flow capacity for driving larger actuators or multiple devices. Ensure your air supply can meet the demand.

3. Wiring:​ Use shielded twisted-pair cable for the 4-20mA signal. In hazardous areas, follow local electrical codes for intrinsically safe installations.

4. Configuration:​ May require HART communicator or configuration software for initial setup (zero/span adjustment, characteristic curve).

5. Mounting:​ Ensure proper orientation and accessibility for maintenance. Avoid mounting in areas with excessive vibration or temperature extremes beyond the specified range.
