Siemens Safety Realy Monitors AS-Interface 3RK1105-1BE04-1CA0

Siemens Safety Monitors AS-Interface

An ASIsafe Basis Safety Monitor Relay is a specialized safety device used to monitor and manage safety functions in industrial automation systems that utilize the AS-Interface (AS-i) communication protocol. The communication of AS-i safety modules and triggers a safe shutdown when a fault or unsafe condition is detected.

Key Specifications & Features:

• Function: It serves as a central safety controller for an AS-i network. It monitors safety inputs from E-stop buttons, safety gates, or light curtains that are connected via AS-i safety slaves.
• Integrated Diagnostics: The relay continuously monitors the communication on the AS-i bus. If it detects an invalid code sequence from a safety slave, it immediately de-energizes its safety outputs.
• Outputs: The relay typically has one or more safe output relays that directly control the power to safety-related circuits, such as contactors or motor brakes.
• Compatibility: It is an AS-i system with an AS-i master and various AS-i safety input and output modules.

Product Status:

The ASIsafe Basis Safety Monitor Relay is a mature product, and some specific models (like some from Siemens’ 3RK1 series) have been announced as discontinued or are in the process of being phased out.
