Product Description:
The EEA-PAM-525-C-32 power amplifier is engineered to deliver precision control for hydraulic systems. It offers exceptional accuracy and robust output. This module is suitable for industrial environments that require precise operation and stability.
This EEA-PAM-525-C-32 power amplifier provides a control output supply of + 15 V exclusively for LVDTs. The output voltages for control include + 10 V (± 1 %) at 5 mA on pin z2 and – 10 V (± 1 %) at 5 mA on pin b2. Both z2 and b2 output pins exhibit a ripple of less than 20 mV peak-to-peak and a temperature drift below 1 mV/°C (0.5 mV/°F) across a temperature range of 0 to 50°C. These outputs are protected against short circuits. The command signal inputs of this module include direct voltage pins b8, b6, z8, and b10 with inverting-voltage pin z10. The input voltage range is ± 10 V with an impedance of 47 kΩ while the current input (pin z6) accepts ± 20 mA with an impedance of 100 Ω. This model’s command voltage source at pin d20 outputs ± 10 V at 10 mA. Command voltage polarity can be selected using pin d2 that ranges from 0 to + 5 V for flow from port P to A and + 10 V to + 40 V for flow from port P to B.
This Vickers EEA-PAM-5**-C-32 power amplifiers series unit also features logic inputs with a switch on voltage of + 10 V to + 40 V and a switch off voltage below +5V. Logic control of this module is achieved through pins d10, d12, d14 or d18. Command voltage inputs at pins d22, d24, d26 and d28 support a range of ± 10 V for precise valve control.
Frequently Asked Questions about EEA-PAM-525-C-32:
Q: Can the EEA-PAM-525-C-32 manage short-circuit protection for LVDT outputs?
