Product Description:
The model EEA-PAM-571-A-33 is a Power Amplifier designed for precise industrial automation applications. It ensures efficient control of electrohydraulic systems. This amplifier provides command input ramps, analog feedback sensor interfaces and an automatic p/Q switch over function. It requires a single 24 V power supply.
This EEA-PAM-571-A-33 power amplifier features multiple analog and digital inputs and outputs for accurate signal processing. The command input section includes direct voltage inputs (b6, b8, b10, z8) and an inverting voltage input (z10) with a ± 10 V voltage range and 47 kΩ input impedance. A current input (z6) supports ± 20 mA with 100 Ω impedance. Additional inputs include a feed forward input (d8) with 6 kΩ impedance and an input for the ramp generator (d28) with 10 kΩ impedance. Sensor inputs (d2) of this amplifier accept 0 – 10 V or ± 10 V signals. These input features a 1 MΩ impedance for voltage and 100 Ω impedance for current signals. They supports 4 – 20 mA or 0 – 20 mA. The reference voltage outputs include + 10 V and – 10 V at 5mA (z2, b2).
Digital outputs of this Vickers EEA-PAM-571-A-33 power amplifier provide sensor failure detection (d18) indicating sensor failure or normal operation. Feedback outputs (d10) ensure command signal matching, operating at Vcc -2 V (<3 V) with a load current of ≤100 mA. The analog outputs include a PID controller output (d4), error signal output (d22) and feedback signal output (d24) all with a ± 10 V range and ≥10 kΩ load impedance. The ramp generator output (d26) delivers ± 10 V with a ≥5 kΩ load resistance. It features built in test capabilities and short circuit proof outputs.
