Redundant I/H Converter, Redundant Current to Pressure Converter Assembly, Dual/Duplex Current to Pressure Converter (DX-CPC)
I/H Converter Module Type DSM, Redundant Current to Pressure Converter CPC-DX
Voith I/H converter modules are redundant dual/duplex current-to-pressure converters (DX-CPC), which adjust hydraulic positioning cylinders by means of a pilot valve in processes requiring high availability. The positioning cylinders operate a valve that controls the mass flow needed to drive machinery. The pressure control module provides very precise and high dynamic control of the mass flow.
An I/H converter module consists of two I/H converters connected in parallel. An I/H converter changes a constant input pressure into a variable output pressure. A standard 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.
Every I/H converter has a monitoring circuit that detects a malfunction of the converter. In the event of converter malfunction, a hydraulic maximum selection circuitry ensures that the other I/H converter assumes control automatically. This makes it possible to remedy the cause of the malfunction during operation.
The Mean Time Between Failures (MTBF) for Voith pressure control modules is over 20,000 years. Your equipment runs for a very long period of time without unplanned downtime; availability is increased.
