Stop Paying an Electrician to Wire Your Hydraulic Valves
Stop Paying an Electrician to Wire Your Hydraulic Valves
How much of your machine-building budget is spent on specialized electrical labor? For many, wiring complex analog hydraulic valves is a major cost center—a task requiring skilled electricians to handle expensive, shielded cables.
What if you could eliminate most of the labor cost?
With the 4WRPEH directional control valve with IO-Link, you can. This isn't just a new valve; it's a new way of thinking about machine cost and efficiency.
The Analog Tax: Paying for Complexity
Traditionally, connecting a proportional valve meant paying an "analog tax":
- The Cable Tax: Paying for expensive, multi-wire shielded cables.
- The Labor Tax: Paying a specialized electrician to ensure those cables were wired perfectly.
- The Downtime Tax: Paying in lost production when a fault occurred, and a technician had to spend hours with a multimeter to figure out what went wrong.
How IO-Link Eliminates the Tax
The 4WRPEH with IO-Link uses a standard, low-cost 5-wire M12 cable. This has two massive implications for your bottom line.
First, you don't need a specialist. The M12 connector is error-proof. It can be installed quickly and correctly by a general machine assembler, not an electrician. This directly reduces your labor costs and speeds up your build time.
Second, troubleshooting becomes instant. The IO-Link valve is an intelligent device. If there's a problem, it tells you exactly what and where it is.
- The HMI doesn't just say "Machine Fault." It says, "Valve on Axis 3 has an undervoltage error."
- You can see the valve's material number, its original installation date, and its current temperature, all from the control panel.
This isn't just "better diagnostics"; it's the difference between a five-minute fix and a five-hour service call.
The Easiest Upgrade You'll Ever Make
The best part? This cost-saving technology is built on a foundation of proven Rexroth performance. The 4WRPEH delivers the servo-quality precision and reliability you expect. You're not trading performance for simplicity—you're getting both.
By simplifying the most complex part of hydraulic integration, the 4WRPEH with IO-Link offers one of the clearest and most immediate returns on investment in modern automation. It's time to stop paying the analog tax.
