Information About 440R-C23017

The 440R-C23017 is part of Allen-Bradley’s GuardMaster Minotaur MSR series built to support safety circuits requiring monitoring of emergency stops, safety gates or interlock devices. It offers internal selectable input configurations supporting either one normally-closed or two normally-closed input channels, enabling flexible wiring to meet application needs. The relay includes three normally-open safety outputs and one normally-closed auxiliary contact, providing secure output switching for safety-related stop functions. With its compact housing, dual-channel architecture and 24 VAC/DC compatibility, the unit integrates smoothly into industrial control panels and complies with safety system design requirements.

Key Features:

  • Dual-Channel Input Monitoring: Supports one NC or two NC selectable input configurations for safety devices such as E-Stops or gate switches.
  • Three NO Safety Outputs: Provides fail-safe switching contacts for controlling power to hazardous motion or equipment.
  • NC Auxiliary Contact: Supplies status feedback for controllers, indicator circuits or system monitoring functions.
  • 24 VAC/DC Power Compatibility: Operates on common control voltages for flexible installation across industrial panels.
  • Internal Selectable Inputs: Allows configuration adjustments to match safety device wiring and circuit requirements.
  • GuardMaster Minotaur Design: Engineered for robust safety performance, compliant operation and long service life.
  • Compact Relay Housing: Installs easily within control cabinets while maintaining strong electrical reliability.
  • High-Integrity Contact Architecture: Ensures dependable performance in safety stop and interlock monitoring applications.

Frequently Asked Questions about 440R-C23017
Question: What is the 440R-C23017 used for?
Date Update:17/06/2025
Answer:

The 440R-C23017 is a Minotaur safety relay designed to monitor safety input devices such as:

  • Emergency stop buttons (E-stops)
  • Safety gate switches
  • Light curtains or safety mats

It ensures that when a safety condition is triggered, power to the hazardous machine is removed through monitored safety outputs.

Question: What are the key features of the 440R-C23017?
Date Update:17/06/2025
Answer:

While the exact datasheet isn’t retrieved, most Minotaur relays like this offer:

  • Dual-channel safety input monitoring
  • Redundant and monitored contacts
  • LED indicators for status diagnosis
  • Safety category up to Category 4 / PLe (ISO 13849-1) depending on wiring
  • Removable terminal blocks for ease of replacement
Question: How do I wire the 440R-C23017?
Date Update:17/06/2025
Answer:
  • Input terminals connect to the safety device (e.g., E-stop or gate switch)
  • Reset terminals allow automatic or manual reset options
  • Output contacts control machine power circuits (redundant contacts)

Use the reset and feedback loops to monitor external contactors for consistency.

Always refer to the wiring diagram printed on the side of the relay or the official installation manual.

Question: Can I hot-swap or field-replace this relay easily?
Date Update:17/06/2025
Answer:

Yes — most Minotaur relays feature removable terminal blocks, which allow for fast replacement without rewiring. Still, machine power should be fully shut down and locked out before any replacement or maintenance.

Question: Is the 440R-C23017 still available for purchase?
Date Update:17/06/2025
Answer:

It may be discontinued or limited to surplus inventory, as many of the Minotaur models are being replaced by the GSR (Guardmaster Safety Relay) series. However, it can often be found:

  • Through industrial automation suppliers
  • On Rockwell-authorized distributor websites
  • In refurbished or new condition from surplus providers
