Allen-Bradley MSR126.1T 440R-N23114 Safety Relay – Guardmaster Series

Technical Dossier

Product Details And Specifications

The Allen-Bradley MSR126.1T (Catalog No. 440R-N23114) is a Guardmaster-series dual-channel safety relay designed for emergency stop, safety gate, and light curtain monitoring applications. As Rockwell Automation progressively transitions its safety relay portfolio toward newer Guardmaster SI units, the MSR126.1T has entered a phase of constrained availability — making proactive procurement and RFQ-reviewed sourcing status sourcing a critical priority for plant engineers and MRO buyers managing SIL 2 / PLd safety circuits.

Procurement Specifications

Procurement decisions for safety relays are rarely about unit price alone. The true cost of a safety relay failure or sourcing delay includes:

• RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.
• Export Documentation: Full commercial invoice, packing list, certificate of origin, and HS code declaration (HS: 8536.49) provided for customs clearance in EU, US, Southeast Asia, and Middle East markets.
• Payment Flexibility: T/T (wire transfer), PayPal, Western Union, and LC accepted. Multi-currency invoicing available (USD, EUR, HKD).
• Logistics: DHL Express, FedEx International Priority, and UPS Worldwide available. Standard transit: 3–7 business days to most destinations. Air freight consolidation available for bulk orders.
• Packaging: Original OEM packaging where available; anti-static ESD packaging with moisture barrier for all relay shipments.

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.

Q: Are there compatible replacement options if this exact model is unavailable?
A: The Allen-Bradley 440R-N23114 can in many applications be substituted with the Guardmaster SI series (440R-S13R2) with appropriate wiring adaptation. Our technical team will advise on compatibility before recommending any alternative.
