MPU-M1

The MPU-M1 is the processor card for SIL3-certified safety tasks. Two redundantly operating processor cores process safety applications and monitor each other, achieving extremely high fault diagnostics. Integrated interfaces support serial Modbus RTU as standard as well as redundant Ethernet with Open Modbus TCP. Safety-related data can be exchanged between GA systems via the GA safeTCP protocol.
