Product Description

The 440R-W23221 is a versatile safety monitoring relay that features two dual-channel inputs. It can monitor two separate safety functions (such as two E-stops or one E-stop and one light curtain) or be configured for a single safety function with higher complexity. The “DI” designation stands for Dual Input, reflecting its ability to evaluate multiple safety circuits simultaneously. It utilizes a slim 22.5mm housing to save precious cabinet space and features a single-wire safety connection for easy expansion.

Product Parameters

• Input Configuration: 2 Dual-Channel Universal Inputs

• Safety Outputs: 3 NO (Normally Open) Solid-State Outputs

• Auxiliary Outputs: 1 NC (Normally Closed) Solid-State Output

• Supply Voltage: 24V DC

• Power Consumption: 3.5 W

• Response Time: < 25 ms

• Safety Rating: PLe, Category 4 (ISO 13849-1); SIL CL3 (IEC 62061)

• Housing Width: 22.5 mm

• Terminal Type: Removable Screw Terminals (depending on specific sub-batch, though standard for this series)

• Operating Temperature: -5°C to +55°C (23°F to 131°F)

Product Advantages

• Compact Design: The 22.5mm width allows for high-density mounting on DIN rails, reducing the overall footprint of the control panel.

• Versatility: Supports a wide range of safety devices, including mechanical switches, E-stops, light curtains, and pressure mats.

• Simplified Wiring: Features “Single Wire Safety” (SWS) technology, which allows for the connection of multiple GSR relays with a single wire, reducing labor and complexity.

• Diagnostic Capabilities: Integrated LED indicators provide immediate visual feedback on power, input status, and faults, speeding up troubleshooting.

• Configuration Flexibility: Uses rotary switches on the front face to set the functional logic (reset mode and input type), eliminating the need for complex software programming for basic setups.

Precautions for Use

• Power Supply Requirements: Always use a PELV/SELV-compliant 24V DC power supply to ensure safety isolation.

• Configuration Locking: After setting the rotary switches to the desired logic, the device must be cycled through a power-up sequence or “locked” according to the manual to ensure the settings are registered.

• Load Limits: Do not exceed the rated current for the solid-state outputs. If switching high-power AC loads, interposing relays or contactors must be used.

• Environmental Protection: Ensure the relay is mounted in an enclosure with at least an IP54 rating to protect against dust and moisture, as the unit itself is designed for clean industrial environments.

Product Applications

• Emergency Stop Monitoring: Ideal for machines requiring multiple E-stop buttons across a large perimeter.

• Gate and Interlock Guarding: Monitoring safety switches on machine doors to ensure the machine stops when a guard is opened.

• Light Curtain Integration: Processing signals from Type 4 light curtains in robotic cells or high-speed assembly lines.

• Multi-Zone Safety: Using the Dual Input feature to manage two distinct safety zones within a single piece of equipment.

• Modernization Projects: Replacing older, bulky safety relays with a more modern, space-efficient solution that offers better diagnostics.
