Voith electro-hydraulic I/H converters are current-to-pressure converters (CPC), which adjust hydraulic positioning cylinders by means of a pilot valve. The positioning cylinders operate a valve that controls the mass flow needed to drive machinery. Voith I/H converters (CPC) ensure very precise and high dynamic control of the mass flow. I/H converters change a constant input pressure into a variable output pressure. A standard 0/4 – 20 mA signal specifies the output pressure. The major components of the I/H converter are a hydraulic unit and a force-controlled electromagnet.

The I/H converter features a simple and compact design which ensures reliable operation. The Mean Time Between Failure (MTBF) for a Voith I/H converter is over 600 years. Your equipment will run for an exceptionally long period of time without unplanned interuptions. Additionally, the I/H converter (CPC) is also available in a redundant design (hot redundancy): DSM I/H Converter Module (DX-CPC).

Advantages and benefits

The Mean Time Between Failure (MTBF) is over 600 years. Your equipment operates very reliably. Productivity increases and the costs associated with lost production remain low

Voith I/H converters are insensitive to contaminated pilot oil. Turbine lubricating oil is suitable as the operating fluid. One oil supply system for both lubricating and pilot oil suffices. Maintenance is simple, which helps you lower operating costs

Very good control response, almost no hysteresis, and a resolution better than 0.1% ensures very fast and accurate control. You benefit from having a stable process with high product quality

Reduced system integration costs facilitated as connections are industry-standard which means the I/H converter can be easily integrated into your equipment. Standard adapter plates are available to allow the I/H converter to interface with systems designed for Woodward CPC and CPC-II converters

The output pressure range can be adjusted easily on-site by means of potentiometers. This allows you to adjust the output pressure for the application quickly and without any delays

For use in hazardous areas, we offer certified explosion proof I/H converters
