DescriptionParker Series ED104 Power Amplifiers | for Pressure ValvesED104 Electronic module for the control of proportional pressure relief valves. The pressure values and the changing sequence are determined by externally applied command signals as well as internal limit and ramp potentiometers. There is a linear relationship between input signal and the solenoid current. The pressure value behaves of the valve characteristics and depends partly of the flow.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.
