The components 3RK1301-0JB00-1AA0, 3RK1903-1BB00, and the software key G001213 form a complete Siemens SIMATIC SIRIUS 3RK1 Safety Relay System. This is a modular safety system designed to monitor safety devices like E-Stops, safety gates, light curtains, and two-hand controls on machinery.

The system is built around a central safety module to which various expansion modules can be added, allowing for a flexible and scalable safety solution.

1. 3RK1301-0JB00-1AA0 – Central Safety Module

This is the brain of the safety system.

• Product Family: SIMATIC SIRIUS 3RK1 Safety Relays

• Product Title: SIMATIC SIRIUS 3RK1301 SAFETY RELAY MODULE BASIC UNIT 24VDC

• Short Description: This is the central processing unit for the safety system. It is responsible for monitoring the connected safety inputs and controlling the safety outputs.

Key Features & Functions:

• Type: Basic Unit / Central Module

• Safety Category: Meets requirements for Category 4 / PL e according to EN ISO 13849-1, making it suitable for the highest safety demands where a single fault cannot lead to the loss of the safety function.

• Number of Safe Inputs: It has 2 dual-channel safety inputs (typically labeled S11-S12 and S21-S22). These are used to connect safety devices like E-Stop buttons or safety gates in a redundant (two-channel) configuration for fault detection.

• Number of Safe Outputs: It provides 3 safe semiconductor outputs (typically labeled OUT1, OUT2, OUT3) and 2 safe relay contactors (force-guided relays, K1 and K2).

• Operating Voltage: 24 V DC

• Configuration: It is configured using a configuration plug (included or separate) that is inserted into the front of the module. This plug defines how the inputs are monitored (e.g., for a single E-Stop, a two-hand control, etc.).

• Expansion: It has a built-in connector for directly attaching expansion modules like the 3RK1903-1BB00 to increase the number of available inputs and outputs.

Typical Use Case: Used as the main controller to monitor a critical E-Stop circuit on a machine.

2. 3RK1903-1BB00 – Input/Output Expansion Module

This module expands the capabilities of the central safety module.

• Product Family: SIMATIC SIRIUS 3RK1 Safety Relays

• Product Title: SIMATIC SIRIUS 3RK1903 EXPANSION MODULE 4 IN 2 OUT

• Short Description: This is an expansion module that adds extra safety inputs and outputs to the central 3RK1301 module.

Key Features & Functions:

• Type: Expansion Module

• Safety Category: Also meets Category 4 / PL e when used with the compatible central module.

• Number of Safe Inputs: It adds 4 dual-channel safety inputs.

• Number of Safe Outputs: It adds 2 safe semiconductor outputs.

• Connection: It connects directly to the right-hand side of the 3RK1301 central module without any wiring between them, creating a compact “slice” of safety logic.

• Power Supply: It receives power and communication from the central module.

Typical Use Case: You have a machine with a main E-Stop (connected to the 3RK1301) and an additional safety gate with two magnetic switches (connected to the 3RK1903). The expansion module allows you to monitor all these devices with a single, integrated system.

3. G001213 – Software License Key (SIPLUS TOP PRODUCT)

This is a software license, not a hardware component.

• Product Title: SIPLUS SIRIUS SOFT ES 2008 LIC.KEY PKG. POWERPACK

• Short Description: This is a software license for SIRIUS Soft ES, a configuration and commissioning tool that runs inside Siemens’ SIMATIC STEP 7 engineering framework.

Key Features & Functions:

• Software Tool: SIRIUS Soft ES (Engineering System)

• Purpose: It allows you to configure, parameterize, and test the 3RK1 modular safety systems on your PC instead of manually setting them up with hardware configuration plugs.

• Benefits:

  • Graphical Configuration: Drag-and-drop function blocks for different safety functions (E-Stop, Gate, Two-Hand, etc.).

  • Automatic Code Generation: The software automatically generates the configuration data.

  • Simulation: Test your safety logic before downloading it to the hardware.

  • Documentation: Automatically generates documentation for the safety circuit.

• Usage: The license key G001213 is used to activate this software functionality within the STEP 7 environment.
