809-A03E Allen Bradley

Description

Product Name: 809-A03E   Allen Bradley Output module

Product details:

The Allen-Bradley 809-A03E is an industrial control component, specifically identified as a Current Relay. Relays in this series are designed to monitor electrical current and provide a switching action when the current level exceeds or falls below a set point.

• Type: Current Relay
• Trip Feature: Instantaneous Trip (meaning the relay activates almost immediately when the current threshold is reached, without a time delay).
• Status: This product model was Discontinued by the manufacturer (Allen-Bradley) around February 2010.

2. Product Specifications (产品参数)

Based on typical product listings for this specific model, the key electrical specifications are:

3. Product Advantages (产品优势)

For its time, and in comparison to simpler control methods, the 809-A03E offered several operational benefits:

• Instantaneous Protection: The instantaneous trip feature provides very fast fault detection, which is crucial for protecting sensitive equipment from sudden overcurrent conditions before damage can occur.
• Dual AC/DC Capability: The relay is rated for both Alternating Current (AC) and Direct Current (DC) applications, offering flexibility in different control systems.
• Adjustable Trip Range: The unit allows the user to set a specific current threshold within the defined range (e.g., 2.1 – 6.1A AC), making it adaptable to various load requirements.
• High Voltage Rating: With a 600V AC/DC rating, it is suitable for use in high-power industrial control circuits.

4. Precautions (注意事项)

When handling and installing this type of discontinued industrial control device, the following general precautions apply:

• De-energize Power: Always ensure the control panel and circuit are completely de-energized (power shut off) and verified with a multimeter before installation, wiring, or maintenance.
• Correct Wiring: Adhere strictly to the wiring diagram provided on the unit or in the official documentation to prevent short circuits or improper operation.
• Verify Range: Ensure the required operating current and trip settings for your application fall within the specified AC/DC trip ranges of the 809-A03E.
• Check Condition (for older units): Since the product is discontinued, if you are using a used or surplus unit, visually inspect for any signs of damage, corrosion, or wear on the terminals and casing.
• Replacement/Upgrade: Because it is discontinued, if the unit fails, a direct replacement may be difficult or impossible. Consider having a modern equivalent (like a newer Allen-Bradley E300 or similar protective relay) identified for a potential system upgrade.

5. Product Applications (产品应用)

Current relays like the 809-A03E are essential components for protection and monitoring in industrial settings. Typical applications include:

• Motor Overload Protection: Monitoring the current drawn by electric motors to shut them down instantly if they stall or experience a severe overload (Locked Rotor Current).
• Equipment Protection: Providing fast shutdown of machinery when an abnormal current surge (such as a short circuit or ground fault) is detected.
• Process Monitoring: Signaling an alarm or initiating a corrective action when the current draw of a critical load (like a heater or pump) falls outside of normal operating limits.
• Control Panel Integration: Acting as a critical input device to a larger Programmable Logic Controller (PLC) or control circuit.
