2 Detailed Explanation of Each Code
- 440R – Product Family Identifier
440: Standard prefix for Rockwell Automation safety products, dedicated to the Guardmaster safety relay line
아르 자형: Abbreviation for Relay, defining the product as a safety relay, distinguishing it from other 440-series devices such as safety switches (440G) and safety controllers (440기음)
- B – Subseries Code (MSR5T)
B Corresponds exclusively to the Minotaur MSR5T model, a monitoring safety relay with key features:
Single-or dual-channel input (this model uses 1NC single-channel input)
3 independent redundant normally open safety outputs to ensure reliable safety function
1 normally closed auxiliary output for status feedback signals
Supports output monitoring to detect faults in the safety output circuit
