Product Description:

The > is an advanced solution designed to provide precise control for industrial automation applications. It offers reliable performance and high durability that caters to the needs of various control systems.

The > features multiple analog outputs including a PID controller output (d4), an error signal (d22) and a feedback signal (d24) to ensure detailed control and monitoring capabilities. The output signals of this model have a voltage range of ± 10 V and are equipped with short circuit protection with a load impedance of at least 10 kΩ for enhanced reliability. This module’s ramp generator output (d26) supports a load resistance of at least 5 kΩ with the same voltage range of ± 10 V. The alarm output system of this power amplifier is designed to indicate drive output status and includes a set alarm (z12) feature that activates 500 ms after the amplifier is powered on. When the alarm is triggered, the output voltage equals the supply voltage minus 2 volts with a maximum output current of 50 mA. In the case of a solenoid overload, the output voltage drops to 0 to ± 2 volts and remains in this state until manually reset. This unit also supports re enabling the system via pin z24 after an alarm event.

This EEA-PAM-5**-D-32 power amplifiers series module’s ramp active indicator monitors the ramping status of the drive output to deliver precise feedback. When the drive ramps up, the output exceeds 10 V while ramping down results in an output below –10 V. If there is no ramping, the output stabilizes around 0 ± 10 V. The output resistance for the ramp status signal is maintained at 10 kΩ to ensure consistent and interference free readings.

Frequently Asked Questions about EEA-PAM-561-D-32:

Q: What happens during a solenoid overload in the Vickers EEA-PAM-561-D-32?

A: When a solenoid overload occurs, the output voltage drops to 0 to ±2 V. It remains in this state until manually reset, ensuring no uncontrolled reactivation.

Q: How does the Vickers EEA-PAM-561-D-32 maintain signal stability during ramping?

A: The EEA-PAM-561-D-32 uses a ramp active indicator to monitor drive output changes. During ramp-up, the output exceeds 10 V, while ramp-down drops below –10 V, stabilizing around 0 ±10 V when idle.

Q: What protection does the Vickers EEA-PAM-561-D-32 offer for short circuits?

A: This model provides short-circuit protection on its ±10 V analog outputs. It ensures reliable performance by maintaining a minimum load impedance of 10 kΩ to prevent disruptions or output failures.

Q: How does the alarm output system in the EEA-PAM-561-D-32 function?

A: The z12 alarm output activates 500 ms after power-on to indicate drive output status. If triggered, the output voltage equals the supply voltage minus 2 V, with a max output current of 50 mA.

Q: How does the EEA-PAM-561-D-32 ensure consistent feedback signal readings?

A: The feedback signal (d24) maintains an output resistance of 10 kΩ to prevent signal interference. This ensures precise and stable monitoring, critical for high-performance control system accuracy.
