Allen-Bradley - MSR14T - Minotaur Monitoring Safety Relay
The Allen-Bradley MSR14T is a safety relay from the Minotaur series, designed to monitor safety devices such as emergency stop buttons, safety gates, and light curtains. It provides immediate safety outputs and supports various input configurations, ensuring reliable safety control in industrial applications.
Key Features:
• Flexible Input Monitoring: Supports single-channel (1 N.C.) or dual-channel (2 N.C.) inputs, accommodating a wide range of safety devices.
• Immediate Safety Outputs: Provides normally open (N.O.) safety outputs, allowing for direct control of actuators or contactors.
• Auxiliary Output: Includes a normally closed (N.C.) auxiliary output for status monitoring.
• Cross-Fault Monitoring: Detects cross faults in dual-channel configurations, enhancing system reliability.
• Configurable Reset Modes: Offers automatic/manual or monitored manual reset options to suit application requirements.
• Compact Design: Features a slim housing, allowing for efficient DIN rail mounting and space-saving installations.
