Allen-Bradley - MSR138.1DP - Minotaur Monitoring Safety Relay
The Allen-Bradley MSR138.1DP is a versatile safety relay designed to monitor safety devices such as emergency stop buttons, safety gates, and light curtains. It provides immediate and delayed safety outputs, ensuring controlled stopping of machinery in hazardous situations. The relay supports various input configurations and offers both automatic/manual and monitored manual reset options.
Key Features:
• Flexible Input Monitoring: Supports single-channel (1 N.C.), dual-channel (2 N.C.), or light curtain inputs, accommodating a wide range of safety devices.
• Immediate and Delayed Outputs: Provides 2 immediate safety outputs and 2 delayed safety outputs, allowing for differentiated response times in safety applications.
• Auxiliary Output: Includes 1 normally closed delayed 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.
• Removable Terminals: Facilitates easy installation and maintenance with removable terminal blocks.
