Proportional ampliers actuate proportional solenoid valves by converting an input
signal into a corresponding control current.
The proportional amplifier type EMMA has been developed for direct mounting onto
a solenoid valve as a line connector.
It is suitable for controlling proportional single-action and twin solenoids. The
integrated magnetic measuring technology allows the neutral position/spool
position of directly operated solenoid valves to be monitored.
Important parameters (e.g. input signal, minimum current, maximum current, dither,
ramp times, etc.) can be set via a wireless interface using a smartphone or PC.
