Product Dimensions：

The 440R-G23110 is part of the next generation of safety relays from Rockwell Automation. It is characterized by its slim 22.5mm housing and its ability to simplify complex safety systems. This specific "GLP" version is designed to act as a bridge between standard safety devices and the GuardLink system, allowing for detailed status information to be sent over a standard link. It features a rotary switch on the front panel that allows users to select the functional configuration without the need for complex software programming.

Product Parameters

Input Voltage: 24V DC nominal (operating range typically 19.2V to 28.8V DC).
Safety Inputs: 2 dual-channel universal inputs compatible with SensaGuard, light curtains, E-stops, and mechanical switches.
Safety Outputs: 2 Normally Open (N.O.) solid-state safety outputs.
Auxiliary Outputs: 1 Normally Closed (N.C.) solid-state auxiliary output for status signaling.
Housing Width: 22.5mm (0.88 inches) for DIN rail mounting.
Response Time: Typically less than 25ms, ensuring rapid disconnection in the event of a safety breach.
Safety Rating: Capable of meeting PLe, Category 4 according to ISO 13849-1 and SIL CL3 according to IEC 62061.
Configuration: 10-position rotary switch for selecting input types and reset modes (Manual or Automatic).
Terminals: Removable screw terminals for ease of installation and replacement.

Product Advantages

One of the primary advantages of the 440R-G23110 is its Compact Versatility. The slim design saves significant space within the electrical cabinet, while the universal input logic allows it to handle almost any safety device. The Simplified Configuration via the rotary switch eliminates the learning curve associated with software-based safety controllers.

Another major benefit is the Advanced Diagnostics. When used in a GuardLink system, it provides location-specific data, identifying exactly which safety device has been tripped, which drastically reduces troubleshooting time. Additionally, the Solid-State Outputs offer a much longer life cycle compared to traditional electromechanical relays, as there are no physical contacts to wear out over time.

Important Considerations and Precautions

When implementing the 440R-G23110, users must ensure that the Power Supply is a regulated 24V DC source that meets SELV (Safety Extra-Low Voltage) or PELV (Protective Extra-Low Voltage) standards to maintain the safety integrity of the system.

It is critical to perform a Functional Test after installation and configuration to verify that the relay responds correctly to all safety input triggers. During configuration, ensure the Rotary Switch is set to the correct position before powering up; changes made while the unit is powered will trigger a fault. Furthermore, because this unit uses solid-state outputs, installers must verify that the Load Current does not exceed the rated capacity of the outputs (typically 0.5A per output) to prevent overheating or failure.

Product Applications

The 440R-G23110 is widely used in industrial automation where high-level safety monitoring is required in a small footprint.

Robotic Work Cells: Monitoring light curtains and gate interlocks to ensure human operators are safe during robotic motion.
Packaging Machinery: Coordinating multiple emergency stop buttons across long conveyor lines.
Material Handling: Integrating with SensaGuard non-contact switches to monitor access panels on sorting equipment.
Food and Beverage Lines: Providing washdown-compatible safety monitoring when installed in appropriate stainless steel enclosures.
Automotive Assembly: Managing the safety logic for complex workstations where quick diagnostics are required to maintain high production uptime.
