Product Description:
Vickers is a renowned manufacturer of hydraulic components. The company has a long standing reputation for producing reliable and innovative industrial automation solutions. The EEA-PAM-571-A-32 power amplifier is designed specifically to enhance the performance of electrohydraulic systems. This amplifier ensures robust control, stability and adaptability in a variety of demanding applications.
The EEA-PAM-571-A-32 power amplifier features a built in alarm output on pin z12 that enables precise diagnostics. The alarm signal is HIGH when activated to provide a maximum current of 50 mA. In the event of a solenoid overload, the output drops to 0 to ± 2 volts with an output impedance of 50 Ω. Reset after failure is straightforward via the enable/disable function on pin z24. The ambient temperature range of this amplifier for optimal performance is 0 °C to 50 °C (32 °F to 122 °F). The amplifier's weight is 330 g (0.15 lb) that makes it relatively lightweight for its category.
This EEA-PAM-5**-A-32 power amplifiers series unit supports ramps enabled on pin b24 with a voltage between 9.8 V and 40 V. When the circuit is open or the voltage is ≤ 4.5 V, ramps are disabled. The front panel of this model includes two key monitor points: MP1 and MP2 that corresponds to pins b18 and z18 respectively. MP1 allows users to monitor the command signal after deadband compensation, gain and ramps with a voltage range of 0 to 10 V where 10 V equates to maximum output current. MP2 serves as the output monitor point that displays a range of ± 10 V at full stroke for configurations with LVDT feedback or 1 V/A for versions without LVDT. Both outputs feature a short circuit protected impedance of 10 kΩ.
Frequently Asked Questions about EEA-PAM-571-A-32:
Q: How does the Vickers EEA-PAM-571-A-32 amplifier handle solenoid overloads?
A: The built-in alarm output on pin z12 provides diagnostic feedback by outputting 50 mA when active. During solenoid overload, the output voltage drops to 0 to ±2 V with a 50 Ω impedance.
Q: What is the purpose of the ramp function in the EEA-PAM-571-A-32 amplifier?
A: The ramp function stabilizes signal transitions and is controlled by pin b24. It supports a voltage range of 9.8 to 40 V and disables below 4.5 V or with an open circuit.
Q: How can I monitor output performance with the Vickers EEA-PAM-571-A-32 amplifier?
A: The amplifier includes MP1 and MP2 monitor points corresponding to pins b18 and z18. MP1 monitors the command signal up to 10 V after deadband compensation, while MP2 shows ±10 V output at full stroke.
Q: What makes the Vickers EEA-PAM-571-A-32 amplifier lightweight for its category?
A: This amplifier weighs only 330 g (0.15 lb), making it convenient for installation without sacrificing durability. Despite its lightweight build, it supports robust electrohydraulic performance across industrial applications.
Q: How does the EEA-PAM-571-A-32 maintain optimal performance in varying environments?
A: The amplifier operates efficiently within an ambient temperature range of 0 °C to 50 °C (32 °F to 122 °F). This wide range ensures reliability in diverse industrial settings and applications.
