Description
Overview
The Type 590X I/P Transducer converts a variable 4-20 mA electrical input signal into a linearly proportional pneumatic output pressure. Its compact size, light weight, and resistance to shock and vibration make it well suited for demanding process control applications and dense panel installations.
The Type 590X uses open-loop conversion technology and a low-mass magnet to provide accurate pneumatic pressure control at an economical cost. The unit can be mounted in any position and is designed to remain stable in high-vibration environments.
Available output ranges include 3-15 psig, 3-27 psig, and 6-30 psig. FM and CSA approvals are standard, with optional ATEX and UKCA approvals for qualifying applications. A standard DIN rail adapter simplifies installation, while an optional low-temperature configuration supports operation down to -67°F (-55°C).

The Type 590X provides stable current-to-pressure conversion in applications where vibration, mounting orientation, compact size, and hazardous-area approvals are important selection factors.
How to Select the Right Configuration
Selecting the correct Type 590X configuration depends on the required pneumatic output range, supply pressure, ambient temperature, mounting method, and hazardous-area approval requirements.
- Select the 3-15 psig output for standard process-control and valve-positioning applications.
- Select the 3-27 psig output when a wider pneumatic span is required.
- Select the 6-30 psig output for higher-pressure control signals.
- Verify that supply pressure is at least 5 psig above the maximum required output.
- Use the standard DIN rail adapter for compact control-panel installation.
- Use pipe mounting when the transducer will be installed directly in the pneumatic system.
- Select the low-temperature option for ambient temperatures below -40°F.
- Select the ATEX/UKCA approval option when required by the installation.
- Use only clean, dry, oil-free instrument air filtered to 40 microns.
- Confirm that the 2.4 scfm flow capacity is adequate for the connected pneumatic load.
- Use a downstream volume booster if the application requires substantially greater flow capacity.
