Control of hydraulic proportional valves - Interesting facts about the IO-Link plug amplifier
IO-LINK connector amplifier PAM-190-P-IO
With the IO-LINK plug amplifier PAM-190-P-IO from WEST-Elektronik, you can quickly and easily parameterize and control a large number of hydraulic continuous valves or proportional valves from well-known manufacturers such as Bosch Rexroth, Parker, Hydac, Duplomatic, etc. via the IO-Link interface.
What exactly is IO-Link?
- IO-Link (Input / Output) is a globally standardized point-to-point connection (IEC 61131-9) for communicating with sensors and actuators.
- The aim of the IO-Link company community is to develop and market IO-Link as a technology.
- IO-Link is accepted across all manufacturers.
- A large number of sensors with IO-Link interfaces from a wide range of manufacturers are now available.
- In the area of actuators, development is progressing much more slowly. This interface is ideal for controlling hydraulic proportional valves.
Advantages of the IO-Link interface
- Digital and interference-resistant interface
- Simple cabling
- Parameterization directly via the PLC (no special software required)
- Automatic parameterization when replacing devices
- Diagnostic and actual value feedback
- Galvanically isolated supply between the IO-Link interface and the power electronics
In the age of digitalization and Industry 4.0, the transition to the digital interface is unstoppable. Compared to fieldbuses, IO-Link is a point-to-point connection and can therefore replace analog interfaces without major effort
Typical parameterization via a PLC.
Advantage: All IO-Link devices can be addressed via the same parameterization software.

Exemplary applications with the IO-Link plug amplifier PAM-190-P-IO:
- Current-controlled actuation of hydraulic proportional pressure relief valves and/or pressure control valves. In combination with finely regulating hydraulic valves, pressure settings of +/-3 bar can be realized.
- Current-controlled actuation of proportional directional control valves, e.g. to realize precise movements of hydraulic cylinders. For positioning and synchronization control, WEST Elektronik offers, for example, the POS-123 or the UHC-126
- Current-controlled actuation of hydraulic proportional flow control valves or throttle valves in order to achieve precise flow rate specifications, speeds, etc.
The IO-LINK plug-in amplifier PAM-190-P-IO can be delivered at short notice despite the current delivery situation
