Modular safety control - Wieland Electric Inc

The samosPro modular safety control processes up to 96 safety inputs and 48 safety outputs simultaneously. The control monitors safety sensors such as emergency stop pushbuttons, light curtains, and interlocking installations on guard doors. The short reaction time lets protective measures mount closer to dangerous areas of a machine. Measuring just 22.5‑mm wide, the control lets the units be used in construction widths starting from 45 mm. 

Gateways, such as Ethernet/IP, Modbus/TCP, Profibus-DP, and Profinet IO, transmit more than 50 bytes bidirectionally between a PLC or HMI and the samosPro safety control, ensuring fast and comprehensive diagnosis and visualization of control data. Using samosPlan, users program the control. Replaceable programming memory, called samosMemory, holds the relevant application program for the machine or system.
