Product Short Description

Product Brief Introduction

Compact DIN rail mount digital proportional amplifier designed and manufactured by Atos Italy for closed-loop control of electro-hydraulic proportional flow and pressure valves with integrated LVDT spool position feedback. Model E-ME-AC-05F converts standard industrial analog command signals into high-precision regulated current output for proportional valve solenoids, executing digital closed-loop spool position regulation, fault diagnosis, and parameter configuration via front panel interface or USB software tool.

  8. Overcurrent, overheating, and short-circuit automatic latching shutdown protection with reset trigger via power cycle

Working Principle

24 VDC input power feeds internal isolated switching power supply generating regulated low-voltage digital logic and high-current solenoid drive power. External analog command signal is digitized via high-resolution ADC and compared against LVDT spool position feedback digital value in 32-bit microcontroller closed-loop algorithm. The controller calculates required output current magnitude and polarity, driving high-frequency PWM power stage to deliver precise proportional current to hydraulic valve solenoid, adjusting valve spool position to match target setpoint. All user-configurable ramp times, dead-band compensation, gain values and fault thresholds are saved to non-volatile flash memory. Continuous monitoring circuits detect solenoid short-circuit, LVDT signal loss and supply voltage deviation, activating fault alarm output and safety shutdown sequence upon limit violation.

Applicable Industries

Metal forming hydraulic press machinery, injection molding machine motion control, steel mill rolling mill hydraulic actuation, construction machinery test benches, wind turbine pitch hydraulic control systems, automated robotic hydraulic gripping equipment, aluminum extrusion production line proportional flow control systems

Installation Requirements

  1. Horizontal mounting on standard 35 mm EN DIN rail; vertical mounting prohibited to maintain rated heat dissipation performance
  2. Separate hydraulic valve solenoid high-current wiring from low-level analog command/LVDT signal wiring with minimum 15 cm cable separation
  3. All analog feedback and command wiring must use shielded twisted pair cable with shield terminated to cabinet protective earth bar
  4. Maintain minimum 20 mm vertical air clearance above and below amplifier unit for passive convection cooling
  5. Complete valve closed-loop auto-calibration procedure mandatory after initial wiring installation or component replacement

Usage Precautions

  1. Solenoid output short-circuit triggers permanent latching shutdown; full power cycle required to clear fault state
  2. Operating ambient temperature exceeding +55°C requires linear output current derating to avoid internal overheating protection shutdown
  3. Non-Atos DC-excitation LVDT sensors cannot connect directly; external signal converter module required for cross-brand compatibility
  4. Micro-USB port must remain covered with factory dust cap during long-term industrial operation to prevent metal contact oxidation
  5. Firmware upgrade process requires uninterrupted 24 VDC power supply; power loss mid-upgrade corrupts internal control firmware permanently
