Each item is pre-owned but has been carefully maintained and is in excellent condition, ensuring reliable performance. Please note that Marci Network Hardware is not an authorized distributor for the manufacturers or tradenames listed, so the original manufacturer’s warranty does not apply.

What is Refurbished Packaging?
Refurbished packaging refers to the packaging used for a product that has been previously owned, returned, or repaired, and then restored to a like-new or fully functional condition.

The Allen-Bradley Guardmaster MSR310P Safety Relay (440R-W23219) is a compact, industrial-grade safety control relay designed to provide reliable monitoring and switching for machine safety circuits. As part of the Guardmaster (legacy Minotaur/MSR) family, this device is used to implement safety functions such as emergency stop monitoring, safety door monitoring, and safety interlock verification.
It is suitable for applications where machinery must be brought to a safe state under fault or operator-initiated conditions. The relay evaluates inputs from safety devices (such as e-stops and safety gates) and controls auxiliary safety outputs, helping ensure compliance with machine safety requirements.
This particular model has been discontinued by the manufacturer, but units may still be available through surplus or authorized suppliers.
