Product technial information：

The Allen-Bradley 440R-ZBR520AZ1 is a safety monitoring relay from the Guardmaster MSR18T series. It's designed to monitor safety devices in industrial applications. While this specific model may be discontinued, its functionality is often replaced by newer Guardmaster Safety Relays (GSR) with updated features.

Here's a detailed breakdown:

Product Details:

• Type: Safety Monitoring Relay (Minotaur MSR18T series)

• Part Number: 440R-ZBR520AZ1

• Manufacturer: Allen-Bradley (Rockwell Automation)

• Housing Width: 90mm

• Reset: Automatic/Manual Monitored

• Terminals: Fixed

Product Parameters:

• Power Supply: 24V AC/DC & 110V AC

• Contact Rating: 2 Amps @ 24V DC (also specified as 1.5A @ 120V AC, 0.75A @ 240V AC, max 2A @ 24V)

• Inputs: One 2 N.C. (Normally Closed) input, one 1 N.O. (Normally Open) & 1 N.C. input. Some sources also mention 4 N.C. and 1 N.O. inputs.

• Outputs: 5 Safety Outputs (Normally Open), 2 N.C. Auxiliary Relay Outputs

• Category Rating: CAT 4 Rated (likely ISO 13849-1, IEC 62061 compliant, which newer replacements are designed to meet)

• Response Time: Approximately 25 ms

Product Advantages:

• Safety Compliance: Designed to meet relevant safety standards, providing a reliable solution for machine safety.

• Versatility: Capable of monitoring various safety devices due to multiple input and output configurations.

• Monitoring Capabilities: Offers automatic and manual monitored reset options, allowing for flexible system design and ensuring the safe state of the machine.

• Robust Design: Housed in a durable 90mm enclosure.

Important Considerations (Notes):

• Discontinued Product: The 440R-ZBR520AZ1 is a discontinued product. While still available through some suppliers (often as refurbished or surplus), new installations will typically use newer Guardmaster Safety Relays (GSR) like the GSR CI (440R-S13R2) or GSR EM (440R-EM4R2).

• Migration: If replacing an existing 440R-ZBR520AZ1, carefully review Rockwell Automation's migration solutions to ensure compatibility and proper functionality with newer GSR relays. This may involve using an AC to DC converter if the new relay requires DC supply.

• Qualified Personnel: Installation, adjustments, commissioning, use, assembly, disassembly, and maintenance must be performed by suitably trained personnel in accordance with all applicable codes, laws, and standards.

• Risk Assessment: Never put safety equipment into service without a thorough risk assessment of the entire system. Machine safety deals with people's lives and livelihoods, so no shortcuts should be taken.

• Proper Wiring: Adhere strictly to wiring instructions. Incorrect wiring can lead to system failures and safety hazards.

• Voltage and Current: Ensure that the power supply and connected devices are within the specified voltage and current ratings of the relay.

• Hazards: Be aware of potential electrical shock, burn, and arc flash hazards. Always wear appropriate Personal Protective Equipment (PPE) and follow all regulatory requirements for safe work practices.
