Information About 440R-S35011
The Allen-Bradley 440R-S35011 is a standstill monitoring safety relay from the Guardmaster MSR55P series, designed to detect the standstill condition of electric motors by monitoring the back electromotive force (EMF) generated as the motor coasts to a stop.
Key Features:
- Power Supply: 24V DC
- Monitoring Voltage Range: 20 mV to 400 mV
- Inputs: Suitable for one or three-phase motors up to 690V (UL 600V)
- Safety Outputs: Three normally open (N.O.) safety contacts
- Auxiliary Outputs: One normally open (N.O.) and two solid-state outputs
- Housing Width: 45 mm
This relay operates by measuring the back EMF voltage across the motor terminals. When the back EMF drops below a set threshold, indicating the motor has reached a standstill, the relay's safety outputs are activated. The voltage threshold and time delay before activation are adjustable to accommodate various motor types and application requirements. The 440R-S35011 complies with international safety standards, achieving Performance Level e (PLe) per EN ISO 13849-1 and Safety Integrity Level 3 (SIL 3) according to IEC 61508. It is suitable for applications requiring verification of motor standstill before permitting access to potentially hazardous areas, enhancing safety in industrial environments.
