440R-S13R2 | Allen-Bradley | Guardmaster GSR CI Safety Relay

Product Overview

The 440R-S13R2 serves as a core component of the Guardmaster Safety Relay (GSR) family, specifically the Single Function (CI) model. This module monitors safety-related circuits, including emergency stop push buttons, light curtains, and safety gates. It facilitates high-integrity safety functions in industrial machinery by managing power disconnection through its dedicated safety outputs. We provide this unit as 100% Brand New and factory-original, ensuring your safety architecture meets strict compliance standards without the risks associated with used hardware.

Technical Specifications

The 440R-S13R2 integrates high-density safety logic into a compact 22.5mm housing.

Engineering Advantages

• Universal Input Flexibility: The 440R-S13R2 accepts a wide range of inputs, from traditional dry contact switches to modern OSSD (Optical Output Signal Switching Device) inputs. This versatility allows engineers to standardize on a single relay model across diverse machine generations.

• Single Wire Safety Connection: The integrated single-wire safety output enables the linking of multiple GSR relays using a single conductor. This reduces terminal wiring complexity and significantly shrinks the footprint required in crowded control cabinets.

• Configurable Reset Logic: A simple rotary switch on the front face allows users to select between Automatic/Manual and Monitored Manual reset. This eliminates the need for complex software programming or additional external wiring for different safety protocols.

• Narrow Profile Mounting: The slim 22.5mm DIN-rail design saves valuable rail space. This compact form factor solves the challenge of adding safety functionality to existing panels with limited expansion room.

FAQs

• Is the 440R-S13R2 compatible with older Guardmaster safety devices?

  Yes. The module features "Legacy Compatible" inputs, specifically designed to interface with older safety switches and peripherals without requiring signal conversion.

• What is the benefit of the "Manual Monitored" reset mode?

  Monitored reset prevents the system from restarting if the reset button remains stuck or is tied down. It requires the transition from depressed to released before energizing the safety outputs, adding an extra layer of operational safety.

• Does this unit support expansion for more safety outputs?

  Yes. You can use the single-wire safety output to trigger additional expansion modules, allowing you to scale the number of safety contacts while maintaining the integrity of the original safety circuit.

• Can I replace a standard relay with this module?

  This is a dedicated safety relay with internal redundancy and self-monitoring. You should use it to replace specific safety modules (like the older MSR series) or when upgrading a standard control circuit to meet SIL 3 or PLe safety ratings.
