MSR312P 440R-W23220: delivery record
On this page
The photographed Allen-Bradley Guardmaster label identifies MSR312P, catalogue number 440R-W23220, Series B. It states a 24VDC 5W supply and a DeviceNet interface. The source combines a July 2025 entry and an October note for two units described as about 95% new in appearance, with a one-year supplier warranty. That appearance description is not expanded into unused condition.
Identification and delivery details
Photograph 1 shows a white carton with a window exposing the safety-relay label. Model MSR312P and Cat No. 440R-W23220 are readable, alongside Series B and Lot No. 010 78147. The label is photographed through packaging; the internal components and individual terminal condition were not reviewed.
The output line reads SS 24VDC 3 × 50mA res. That output marking is kept separate from the 24VDC 5W supply. DeviceNet Interface is printed underneath. These labels do not establish a tested network connection, relay operation or the safety performance of an installed machine.
Made in Germany is printed on the label. Its EN574:Typ III C and ambient-temperature 55°C markings are retained as photographed text, without using the visible conformity logos to claim this review certified the unit. The complete application still needs the corresponding product documentation and validation by the responsible engineer.
The July note names Allen-Bradley, 24VDC 5W and Germany and contains a one-unit reference. The 20 October 2025 note separately records two units, 95% appearance condition, a one-year warranty and a then-stated two-to-three-day lead time. That historical lead time is not a current delivery promise. Its 1kg note differs from the zero weight field; neither is asserted as measured net mass.

Only photograph 1 was visually reviewed, after all 17 source photographs and both videos completed GET download and byte/SHA-256 checks. Its label was sufficient for this limited identification review. Photographs 2 through 17 were not viewed and retain neutral source captions. No operational test is claimed from the retained clips.
Matching this part
Match MSR312P, 440R-W23220 and Series B to the required configuration. Verify the applicable supply, solid-state output and DeviceNet requirements using the corresponding documentation before replacing an installed unit.
Confirm which dated entry is being quoted, its actual condition, one-year warranty and present lead time. Request an inspection record for the intended unit and application; the photographed conformity markings do not replace commissioning checks.
