Digital valve controller EMMA

proportionalfor solenoid valveselectric

Product description
The proportional amplifier EMMA is designed for direct mounting on a solenoid valve as a line connector. It controls proportional single-action and twin solenoids and supports single, double and twin solenoid valves. Integrated magnetic measurement monitors the spool/neutral position of directly operated solenoid valves. Key parameters (input signal, minimum/maximum current, dither, ramp times, etc.) are configurable via a wireless interface using a smartphone or PC.

Features and advantages

• Direct assembly onto solenoid valves as a line connector
• Quick and simple commissioning via wireless interface
• Integrated spool/neutral position measurement (proportional and digital)
• Control of single, double and twin solenoid valves
• CAN bus interface for network integration
• Wi‑Fi interface for configuration and diagnostics
• On-board diagnostics and status monitoring
• Functions and settings tailored to HAWE products

Intended applications

• Control of proportional valves in industrial hydraulic systems
• Neutral position monitoring of directly operated solenoid valves
• Integration of analogue proportional valves into CAN bus networks
• Closed-loop position or storage control
