Description
Product Name: 7930-PA Allen Bradley Central control module
Product details:
The Allen-Bradley 7930-PA Auxiliary Power Supply is a modular component designed to provide stable and conditioned power to connected devices within an industrial control panel, often specifically for safety control modules or relays. It ensures the integrity and reliability of the control circuit by offering a dedicated power source.
Product Parameters (Typical Specifications)
| Parameter | Value (Typical) |
| Product Type | Auxiliary Power Supply |
| Catalog Number | 7930-PA |
| Input Voltage | 120V AC or 240V AC (Selectable or specific model variant) |
| Output Voltage | 24V DC (Standard for control systems) |
| Output Current | 1.6A or 2A (Varies based on model and rating) |
| Mounting | DIN Rail Mountable |
| Protection | Short-circuit protection, overvoltage protection |
| Operating Temperature | $0^\circ\text{C}$ to $55^\circ\text{C}$ ($32^\circ\text{F}$ to $131^\circ\text{F}$) |
Note: Specific values (especially voltage and current) should always be verified against the official Allen-Bradley datasheet for the exact 7930-PA variant being used.
Product Advantages (Key Benefits)
- Reliable Power Conditioning: Provides a clean, regulated 24V DC output, which is crucial for the stable operation of sensitive electronic safety and control devices.
- Dedicated Power Source: By isolating the control power from the main machine power, it reduces the risk of noise (electrical interference) affecting the critical safety circuit.
- Industrial Ruggedness: Designed for harsh industrial environments, offering high protection ratings and robust construction.
- Safety Integration: Often integrated into safety systems, ensuring that safety relays and modules receive consistent power to maintain their safety rating and function.
- DIN Rail Mounting: Allows for easy and quick installation and integration into standard control cabinets.
Precautions (Important Notes)
- Verify Voltage: Always confirm that the Input Voltage setting (if selectable) matches the line voltage being supplied (e.g., 120V AC or 240V AC) before applying power. Incorrect setting can damage the unit.
- Current Rating: Do not exceed the maximum Output Current rating (e.g., 1.6A or 2A). Overloading the supply can cause it to shut down or fail.
- Proper Wiring: Ensure all wiring follows local electrical codes and the Allen-Bradley installation manual, paying close attention to grounding and polarity.
- Heat Dissipation: Mount the unit in an enclosure that provides adequate space for ventilation to prevent overheating, which can shorten the product’s lifespan.
- Use with Specified Systems: This module is often designed to work specifically with other Allen-Bradley components (like certain Guardmaster safety relays). Check compatibility.
Product Applications
The 7930-PA is used wherever a reliable, dedicated 24V DC control voltage is needed in an industrial environment, particularly for:
- Machine Safety Systems: Providing power to Guardmaster safety relays, safety light curtains, emergency stop circuits, and safety interlocks.
- Small Control Circuits: Powering PLCs (Programmable Logic Controllers), HMI (Human-Machine Interface) panels, and low-power sensors/transmitters.
- Isolated Control: Applications where the control circuit needs electrical isolation from the main machine power supply to prevent interference.
