Product Description:
Vickers is a trusted name in the hydraulics industry and delivers precision control solutions designed for robust performance in industrial automation systems. The EEA-PAM-535-C-32 power amplifier is engineered to regulate electro-hydraulic proportional valves to ensure efficient and accurate control across various operations.
The EEA-PAM-535-C-32 power amplifier’s primary function is to control solenoid activation via adjustable input voltages to enable precise actuation. When the drive is enabled at pin z24, the solenoid receives a voltage between 9.8 V and 40 V with a resistance of 22 kΩ. Conversely, when the drive is disabled, pin z24 is either open circuited or carries a voltage below 4.5 V, cutting power to the solenoid. Alarm outputs of this module is managed via pin z12 and signals any operational anomalies. In alarm mode, the output voltage drops to within ± 2 V with an output resistance of 50 ohms. This model maintains the alarm state until a reset is initiated. This unit’s ramping controls at pin b24 determine valve switching rates. Applying voltages between 9.8 V and 40 V (22 kΩ) enables ramped transitions for smoother operations while open circuit or voltages below 4.5 V bypass the ramp. The input impedance for external command of this module is configured through four 50 kΩ potentiometers while an external command potentiometer must have a minimum specification of 5 kΩ at 0.25W.
The EEA-PAM-5**-C-32 power amplifiers series unit’s configuration also supports flexible valve performance with adjustable ramp potentiometers to ensure precise control of actuation rates. The solenoid overload protection feature prevents damage by disabling the drive during abnormal current surges and requires manual or automatic reset to resume operations. This amplifier’s design integrates both safety and performance.
Frequently Asked Questions about EEA-PAM-535-C-32:
Q: How does the Vickers EEA-PAM-535-C-32 manage solenoid activation?
A: The EEA-PAM-535-C-32 controls solenoid activation through adjustable input voltages ranging from 9.8 V to 40 V. When pin z24 is enabled, the solenoid receives a voltage for actuation. When disabled, pin z24 is open-circuited or below 4.5 V, cutting power.
Q: What role does ramping control play in the Vickers EEA-PAM-535-C-32?
A: The ramping control at pin b24 regulates valve switching rates for smooth transitions. Applying 9.8 V to 40 V (22 kΩ resistance) enables ramped transitions, while lower voltages bypass ramping for immediate activation.
Q: What are the input requirements for external command potentiometers in the Vickers EEA-PAM-535-C-32?
A: The module’s external command input impedance is configured through four 50 kΩ potentiometers. External potentiometers must meet a minimum specification of 5 kΩ at 0.25 W to ensure precise control and system stability.
Q: How does the Vickers EEA-PAM-535-C-32 prevent solenoid overload damage?
A: The amplifier's solenoid overload protection disables the drive during abnormal current surges. This feature safeguards the system and requires either a manual or automatic reset to resume normal operation, enhancing reliability.
Q: How does the Vickers EEA-PAM-535-C-32 handle operational anomalies?
A: The alarm output at pin z12 signals anomalies by dropping the output voltage to ±2 V with 50-ohm resistance. The amplifier holds this alarm state until reset is performed manually or automatically.
