DescriptionParker Series ET104 Power Amplifiers | for Pressure ValvesET104 Electronic module for the control of proportional throttle valves.The throttle valve opening and its changes are achieved by externally applied commands as well as internal limit and ramp potentiometers. The measured value (Volts) on the module is indirectly proportional with the throttle cross-section or alternatively the resulting volume flow Q (l/min).Features Processing and amplification of the externally supplied positive commands into output signals for the control solenoid. Can be combined with EZ150 or external programmable control. DIP switch from internal ramp generation to external ramp setting. MIN/MAX limiters for matching the working range to the full command signal range. Pulsed low loss amplifier power stage with supporting constant current control for consistant, temperature-independant, solenoid forces. Dither generator with applied frequency to improve static characteristics. Diagnosis by means of diagnostic sockets as well as LEDs for indicating working conditions.
