Wieland Samos PRO compact safety controller

Wieland’s Samos PRO is a compact safety controller for machine and plant applications. Using 22.5 mm wide modules, a programmable safety system can be constructed from a total width of 45 mm.

The system consists of the SP-SCON controller with integrated programming/diagnostic interface, gateway and a series of SP-SDIO or SP-SDI I/O modules.

SP-SCON is the controller module with serial interface and exchangeable program memory and the gateway is used for bi-directional data communication.

The SP-SDIO expansion module has eight inputs and four outputs, while the SP-SDI has eight inputs. An SA-OR-S1 module is available with 2 x 2 relay outputs.

Communication gateways such as SP-CANopen, SP-DeviceNet, SP-Profibus-DP, SP-EN-MOD, Modbus/TCP, SP-EN-IP, TCP/IP and SP-EN-PN, and Profinet are available. All these communication gateways are plug and play with Samos PLAN software.

Users can connect a variety of safety sensors and Samos PRO is able to process up to 96 inputs and 48 outputs at the same time. The system enables switch-off times of less than 10 ms.

The application program is stored on the exchangeable program memory (Samos Memory), which also contains the power supply connection of the system, allowing the application program to always remain available in the control cabinet, even when memories are being exchanged.

Programming is intuitive with the Samos PLAN graphical user interface using a wide variety of safe function blocks. The system is inexpensive as there is almost no wiring work to be done and fast commissioning is possible, with simple integration in Fieldbus systems and industrial ethernet networks.

The controller is compliant with category 4 (EN 954-1), Performance Level PL e (EN ISO 13849-1) and SIL 3 (EN 62061) standards.
