Modular safety system

The Sirius 3RK3 modular safety system MSS offers an enhanced safety solution that combines the functionality of a simple safety relay and a fail-safe programmable logic controller.

The core of the system is the central unit with eight safety-related inputs, one safety-related relay output and one safety-related solid-state output. Up to seven safety or standard expansion modules can be connected to the central unit. The expandability makes the one system easily scalable for applications with as few as three safety functions to as many as 40.

The 3RK3 safety system can provide significant savings where several safety relays are required to combine various safety functions as no wiring is required due to its modular design.

The 3RK3 safety system offers users a substantial reduction on future installation costs when circumstances change or additional functionality is required. Extra functions can be easily added by installing additional expansion modules.

The ES (MSS ES) parameterisation software has the ability to replace the laborious wiring of individual functions by fast and easy online parameterisation.

Siemens is offering an MSS introductory starter package including a basic module, a connection cable and the specific MSS ES parameterisation software.
