Siemens 3RK1105-1BE04-0CA0 ASIsafe Basis Safety Monitor

The Siemens 3RK1105-1BE04-0CA0 is a fundamental safety monitor from the SIRIUS Safety Integrated 3RK1 series, designed for implementing safety functions within AS-Interface Safety (ASIsafe) networks. This module acts as a central safety evaluation unit, monitoring safety-related sensors and devices connected via ASIsafe, such as emergency stop buttons, safety gates, and light curtains.

This safety monitor features 2 fail-safe relay outputs (enabling circuits) to safely shut down machinery or processes and 2 signaling circuits for status indication. With a rapid response time of maximum 40 ms, it ensures quick reaction to safety demands. The unit receives its power directly from the AS-Interface network (typically 24 V DC), simplifying wiring.

Designed for easy installation on a DIN rail, the 3RK1105-1BE04-0CA0 utilizes removable screw terminals for convenient wiring. It is certified for high levels of safety, meeting requirements up to SIL 3 according to IEC 61508 and Performance Level E (Category 4) according to EN ISO 13849-1. This Siemens safety monitor is an essential component for building compliant and efficient safety circuits in automated systems using AS-Interface Safety.

Key Characteristics:

• Function: Monitoring of ASIsafe safety circuits and providing safe outputs.
• Integration: Designed for AS-Interface Safety (ASIsafe) networks.
• Outputs: 2 fail-safe relay outputs (enabling circuits) + 2 signaling circuits.
• Response Time: Max. 40 ms.
