Designed as a safety solution for mechanical and system engineering monitors for all kinds of safety sensors such as emergency stop pushbuttons, light curtains and interlocking installations on guard doors, it has a very short reaction time of few milliseconds that allows protective measures to be mounted closer to dangerous areas of a machine.
Despite their high performance capabilities the individual modules are only 22.5 mm wide, which allows programmable safety solutions in total construction widths starting from 45 mm. The modular safety control satisfies SIL 3 or PL e, among others, according to the current European standards EN 61508, EN ISO 13849-1 and EN 62061 and is CAT 4 compliant.
The user programs the samos PRO safety control simply and intuitively on the graphical programming interface samos PLAN. The numerous safety function modules make it possible to implement complex applications, even without PLC programming languages. The safety control has a replaceable programming memory, called samos MEMORY, which holds the relevant application program for the machine or system. This way the program can be changed easily and without major effort during the machine’s life cycle.
Using the appropriate gateways the safety control can be integrated in standard control solutions and unsafe data can be processed as well.
The new Ethernet gateways SA-EN-IP and SA-EN-MOD now enable users to analyse the control and diagnostic data of the samos system in higher-level management and automation systems. The gateways support the Ethernet protocols Ethernet/IP or Modbus/TCP and have a device-integrated switch.
The modular safety system makes it possible to monitor up to 30 safety sensors and to parameterise them simply with a screwdriver without any software. With eight switchable functions at both the master and the slave the samos modules can be adapted to all safety sensors up to safety category 4 and thus perform functions such as emergency stop, guard door, light curtain, two-hand control or controlled stop.
The modular safety system can be used for zone control in the robotics, manufacturing, packaging, mining, materials handling and component assembly industries.
