SYC80533-1 Allen Bradley

Description

Product Name: SYC80533-1 Allen Bradley Output module

Product details:

The SYC80533-1 is an Allen-Bradley component, typically categorized under Controls & Indicators as an Inverse Time Relay. This type of device is used to protect electrical equipment, particularly motors, by delaying a trip or action based on the magnitude of the current overload. The greater the overload current, the faster the device will trip (inverse time characteristic).

• Manufacturer: Allen-Bradley (Rockwell Automation)

• Part Number: SYC80533-1

• Product Type: Inverse Time Relay (Type 810)

• Function: Electrical protection device, specifically an overcurrent relay with an inverse time characteristic.

📋 Specifications

Detailed, original factory specifications (voltage, current range, trip curves, etc.) are generally found in the official Rockwell Automation product literature for the specific relay series (e.g., the historical Series 810 relays or equivalent modern product). However, general component specifications from suppliers often include:

Note on Specifications: As this is likely a legacy or specific module, definitive operational specifications (like trip class, current range, and voltage rating) require checking the original Allen-Bradley Series 810 or equivalent modern product datasheet, as component distributors often only list basic identification data.

✨ Product Advantages (General for Inverse Time Relays)

While the specific advantages of this older part are linked to its original installation context, the general benefits of using an Inverse Time Overcurrent Relay in industrial applications include:

• Improved Equipment Protection: Provides reliable protection against damaging overcurrent conditions, such as motor stall or phase loss.

• Time-Current Coordination: The inverse time characteristic allows for momentary, harmless inrush currents (like motor starting current) without tripping, while still providing rapid protection for severe faults.

• Selectivity: Enables system coordination, ensuring that only the circuit nearest to the fault trips, minimizing system downtime.

• Longevity: Designed for the demanding environment of industrial control panels, offering high reliability and a long service life.

⚠️ Precautions (General)

When dealing with a protective relay like the SYC80533-1, the following precautions should be observed:

• Proper Installation: Must be installed by qualified personnel according to the manufacturer’s instructions, local electrical codes, and safety standards.

• Calibration/Setting: The relay’s settings (e.g., trip current and time-dial setting) must be correctly calculated and set based on the protected equipment’s full load current and the system’s coordination study. Incorrect settings can lead to nuisance tripping or equipment failure.

• Wiring Integrity: Ensure all control and power wiring is secure and properly sized to prevent wiring faults.

• De-Energization: Always de-energize and lock out power sources before performing inspection, maintenance, or replacement of the device.

🏭 Product Applications

Inverse Time Relays like the SYC80533-1 are vital for industrial control systems, primarily used in:

1. Motor Control Circuits: Providing overload and overcurrent protection for three-phase and single-phase AC motors.

2. Motor Control Centers (MCCs): Integrated into starter units to manage motor protection functions.

3. Industrial Machinery: Used in various machines where components need protection against electrical faults and excessive current draw.

4. Power Distribution: Providing secondary protection for transformers, feeders, and conductors in low-voltage distribution systems.
