Proportional Hydraulic Valve Control Solution – ATOS E-ME-AC-05F | E-ME Series
Where This Product Is Used
The ATOS E-ME-AC-05F analog electronic driver card is engineered for industrial environments where precise, stepless control of proportional hydraulic valves is critical. Typical deployment scenarios include:
- Injection Molding Machines – Closed-loop pressure and flow control during clamping, injection, and holding phases
- Metal Forming Presses – Synchronized multi-axis force control requiring smooth ramp profiles
- Steel Mill Roll Gap Control – High-cycle, high-precision positioning of hydraulic actuators
- Plastic Extrusion Lines – Continuous back-pressure regulation via proportional relief valves
- Marine Deck Machinery – Winch and crane speed control in harsh, vibration-prone environments
- Mobile Hydraulics (OEM) – Integrated into machine control panels requiring compact DIN-rail driver modules
Wherever a PLC outputs a ±10 V or 4–20 mA analog command and a proportional solenoid valve must respond with repeatable, low-hysteresis actuation, the E-ME-AC-05F is the specified solution.

Application-Specific FAQ
Q: Can the E-ME-AC-05F drive double-solenoid proportional valves?
A: Yes. The card provides two independent output channels, each capable of 0–2.5 A, suitable for driving both solenoids of a double-acting proportional directional valve.
Q: Is a separate enable signal required?
A: Yes. The enable input (24 V logic) must be asserted before the driver outputs current. This is intentional for integration with machine safety relays and E-stop circuits.
Q: What PLC analog output resolution is recommended?
A: A minimum of 12-bit resolution (±10 V range) is recommended to achieve smooth, artifact-free valve positioning. 14-bit or 16-bit outputs further improve control quality.
Q: Can I use this driver with non-ATOS proportional valves?
A: Yes, provided the solenoid coil resistance and inductance fall within the driver’s output specification. Consult the ATOS E-ME technical datasheet or contact our engineers for compatibility confirmation.
Q: Is the dither frequency factory-set or field-adjustable?
A: Field-adjustable via on-board trimmer potentiometer, typically set between 100–200 Hz for most hydraulic proportional valves.
