Siemens SIRIUS 3RK3 Series Safety Controller, 8 Safety Inputs, 2 Safety Outputs, 24 V dc / 7643957

Siemens Safety ControllerThe Siemens 3RK3 modular safety system (MSS) is a freely parameterizable modular safety controller. The modular safety relay enables the interconnection of several safety applications. The comprehensive error and status diagnostics provide the possibility of finding errors in the system and localizing signals from sensors resulting in the reduction of plant downtimes. Its basic central unit is used wherever more than 3 safety functions have to be analysed and parameterizing the wiring of safety relays would be time-consuming and expensive to implement. This safety relay reads inputs along with controls outputs and communicates with higher-level controllers via an interface module. The entire safety program of an application is processed in the central unit. At the smallest configuration level, the 3RK3 basic central unit is already functional without the expansion modules that can be connected as options.Features and Benefits8 safety-related sensor inputs 1 safety-related relay output 1 safety- related solid-state output Up to 7 expansion modules can be connected Cyclic data exchange via PROFIBUS is up to 32bit High flexibility and reliability of planning due to a modular design More space in the control cabinet and lower costs thanks to a highly modular quantity structure More functionality and time saving through a parameterizable software system Extensive diagnostics on site and project documentation using the MSS ES software Improved plant diagnostics and higher plant availability through data exchange via PROFIBUSCertificationsEN954: 1 ISO13849: 1 IEC62061 IP20 rated
